Executive Dean’sMessage

The Advanced Water Management Centre (AWMC) was established in 1996, a time when the challenge for the global water industry was focused on the protection of waterways and reduction of nutrients in the environment. The AWMC met this challenge and led the world in nutrient removal, innovative processes and process control of wastewater treatment plants. The impact of this early research is still being applied today by water authorities, both nationally and internationally, and local agro-industries.

Today the AWMC still shows great relevance to the global water industry. This is exemplified by the number of direct collaborators and partners, which include industry, Australian Government bodies (federal, state and local), associations and research institutes.

Excellence underpins all of the AWMC activities. The AWMC research program has changed the way many authorities view their treatment processes and infrastructure. Recently, the AWMC has challenged the way the industry views greenhouse gas emissions, the impact and footprint of treatment systems, nutrient recovery, by-products from waste, and the way the industry can protect and restore our water resources and critical infrastructure.

As the Chair of the AWMC Advisory Board it is my pleasure to introduce the 2010 annual report. It has been another successful and rewarding year for the AWMC team, which promises a future of exciting developments.

Professor Graham Schaffer Executive Dean Faculty of Engineering, Architecture and Information Technology

“The Advanced Water Management Centre is an internationally recognised

centre of excellence in water research and innovation.”

2 AWMC Annual Report 2010

Water does not seem to get out of the headlines – at least not in Australia. If it’s not droughts, then it’s floods, water recycling, desalination plants, water quality, water for the environment, or something else water related! It certainly keeps us busy at the AWMC and continuously poses interesting new challenges.

Looking through this latest summary of our activities, you will notice that we have been very productive across a broad range of topics in the last year. Depending on existing and emerging needs, we adapt our research activities regularly as illustrated for example by the fact that our ‘clean water’ research field has expanded from water recycling to include storm water and drinking water related topics, such as disinfection by-products. At the same time, other ‘hot topics’ such as greenhouse gas emissions, sewer odour and corrosion management, and anaerobic technologies are also performing strongly. We continue to extend our fundamental understanding in both the microbial science and environmental biotechnology areas with the aim to develop the next generation of technologies. These include novel nutrient removal and recovery concepts, biofilm control methods and bioelectrochemical processes, which are now being used in such diverse applications as sulfide reduction in sewers or ferric and phosphate recovery from water recycling sludges.

Our outstanding performance over the last few years has been strongly recognised in 2010. Within The University of Queensland, the AWMC has been recognised in the top tier in terms of our overall research performance in the ‘Institute Based Performance Framework’ assessment. The nation-wide research quality assessment, called Excellence of Research for Australia (ERA), was also very positive for the centre. In the AWMC fields of research, ‘Environmental Biotechnology’ and ‘Environmental Engineering’, UQ’s ranking was in the top category nationally, considered to be ‘well above world standard’. These rankings solidify the AWMC’s position as a world leading water management and research centre.

In November 2010 we had a formal, external review of our overall operations, which concluded that our activity and performance was ‘highly commendable’. Most pleasing was the extremely strong support provided by a range of industry representatives who were interviewed by the review panel. Given the quality of the expert panel, the outcome is particularly valuable and the set of recommendations will help in further improving our operations and overall position within UQ. The recommendations, on a revised funding model, improved accommodation situation and the possible change of the Centre category and status, help to make our long-term future look brighter than ever.

I would like to take this opportunity to thank all of our industry partners and research collaborators, in Australia and internationally, for their ongoing support of our research activities. It is this close engagement with colleagues and partners from industry and academia that help us achieve strong results, which provide direct, mutual benefits to their organisations. And last but not least, my biggest thanks and recognition go to all of our staff and students who are ultimately responsible for achieving such exceptional research outcomes, through their tireless dedication and outstanding commitment to excellence and relevance. This report highlights just some of their achievements over the last year.

I trust you will enjoy reading this report and hope that it will inspire you to get in touch with us or to further continue our valuable collaboration in the future.

Director Professor Jurg Keller

South East Water Upgrades the Mt Martha Biosolids Treatment Train

The Advanced Water Management Centre has provided South East Water (SEW) support in upgrading their Mt Martha wastewater treatment plant digesters. These digesters are now in the order of 20 years old, and have become capacity limited. Rather than replacing the digesters, SEW decided to upgrade them by implementing temperature-phased anaerobic digestion. This process has been investigated extensively at the AWMC, and was found to increase the performance substantially in exactly the application SEW is considering. Dr Damien Batstone assisted Adjunct Prof Ken Hartley in evaluating the existing SEW digesters and providing expected performance outcomes. A subsequent laboratory scale investigation provided information needed to further optimise design of the process.

“Having the AWMC in Australia provides an important research service that we can easily access, but their core research that is also highly relevant, provides us with additional process options, and reduces costs associated with process uncertainty.”, Mr Terry Anderson from SEW corporate strategy.

Personnel: A/Prof Damien Batstone, Dr Paul Jensen and Adjunct Prof Ken Hartley

CSIRO Flagship Cluster – Microbial Diversity in Engineered Systems

In 2010, CSIRO established the Energy Transformed Flagship, which included a cluster aimed at “Biotechnological solutions to Australia’s transport energy and greenhouse gas challenges”. Within this cluster, Dr Korneel Rabaey and Dr Gene Tyson coordinate a significant effort to better understand microbial communities in engineered systems. In collaboration with CSIRO, the project team will set up (bio)electrochemical systems and anaerobic digesters designed and operated to provide fuels or chemicals starting from (waste) biomass. In these reactors, the team will investigate the dynamics and succession of microbial communities, as well as the directed evolution in specific genes such as cellulases. The ultimate goals are to better understand the relationship between microbial communities and system functionality, to mine for novel cellulases or other key degradation genes, and to explore the impact of selective pressure on microbial community development.

Chief Investigators: Dr Korneel Rabaey and Dr Gene Tyson; Project staff: Dr Paul Dennis, Mr Mike Imelfort and Mr Kun Guo; Collaborators: Prof Mark Morrison, CSIRO

SEWEXSeweX is a consulting business based at the AWMC, and is operated under UniQuest Pty Ltd, the commercial arm of UQ. SeweX provides consulting services on the management of sulfide related odour problems in sewer systems to industry. The SeweX (Sewer Transformation) model, which has been developed by the Centre’s strong and internationally leading research team on sewer systems in the past seven years, is primarily used for identifying the problems and investigating options for their mitigation. SeweX also offers strong expertise and tools for offline and online measurement of wastewater characteristics in sewer systems. SeweX has successfully completed a number of consulting projects for water utilities across Australia. Allconnex Water (Gold Coast), Unity Water (Moreton Bay) and South East Water (Melbourne) have all benefited from SeweX services in the past.

The SeweX model is a mathematical model describing the physical, chemical and biological processes in sewers. The model also predicts the formation and emission of methane, a potent green house gas, in sewer networks. The SeweX model won the 2008 International Water Association’s Project Innovation Award (East Asia and Pacific Region) and the 2008 Excellence Award in Research, Development and Innovation of Engineers of Australia (Queensland Division). The model is under continuous enhancement under the Sewer Corrosion and Odour Research (SCORe) project - see page 20.

AWMC Offers Methane Potential and Activity TestingTests developed at the AWMC can provide certainty for anaerobic digestion projects. Anaerobic digestion technologies are an attractive option for the treatment of organic solids, resulting in a net energy generation and production of safe, easy-to-handle residues for beneficial reuse in agriculture. However, the feasibility of such a project is highly dependent on the speed and extent of degradation, which can vary for different materials. The AWMC is a key leader and developer of anaerobic biodegradability, activity and inhibition tests, offering independent testing to enable certainty in feasibility analysis. Ongoing testing of existing projects offers benchmarks to assess process efficiency and product quality. In 2010, BMP testing was used to help Sydney Water Corporation evaluate options for upgrading a large existing wastewater treatment plant. A variation of this test allows independent testing of anaerobic seed biomass, and digester biomass health.

Clients for this testing in 2010 included:- Foster’s BreweryAllconnex WaterMelbourne WaterSydney Water CorporationTrisco FoodsVisy Pulp and PaperWSN Environmental Solutions Australia

Services at the Environmental Microbiology Laboratory (EML)The Environmental Microbiology Laboratory (EML) offers a range of services. The EML is a fully equipped modern laboratory for molecular biology and the culturing of microorganisms. These include facilities for manipulation and fingerprinting of DNA and various forms of enrichment and microbial culture techniques. Our location ensures we have ready access to a range of excellent complementary facilities that include confocal laser scanning microscopy, electron microscopy and flow cytometry. We have strong expertise and experience for molecular characterisation of environmental and industry samples particularly for determining microbial community composition. Services include;

• Microbial community profiling: Denaturing Gradient Gel Electrophoresis (DGGE) and Terminal Restriction Fragment Length Polymorphism (TRFLP) are high throughput methods that are very powerful for the comparison of microbial diversity in a number of samples, for example to examine spatial and temporal population variations.

• Community DNA sequencing and phylogenetic analysis: At the core of identifying microorganisms from environmental samples is sequencing of ribosomal genes. EML uses the latest techniques for cloning and “next-generation” DNA sequencing. Phylogenetic sequence analysis is used to determine the relationship of unknown microorganisms to known representatives.

• Microbial community structure using fluorescent probes: Fluorescently-labeled oligonucleotide probes based upon RNA sequences have achieved wide acceptance in the field of microbial ecology. This technique is widely used to visualise and identify microorganisms directly in the environmental sample, and is known as fluorescence in situ hybridisation (FISH).

Professional Development Courses Offered by the EML

FISH CourseFluorescence in situ hybridisation (FISH) is extensively used for analysis of microbial communities in a wide range of environmental samples such as sludge, seawater, rumen and biofilms. The FISH course is held annually at the AWMC and includes both the theory and practice to provide in-depth details and hands-on experience.

ARB CourseARB is a software package for analysis of DNA sequences and determining phylogenetic relationships between organisms. This is a convenient and widely used package that contains a large cumulative database – simplifying management and sequence analysis for phylogenetic comparisons, and for design and evaluation of FISH probes and primers. ARB incorporates some of the newest and most sophisticated tree-building algorithms. The most recent ARB course at EML was successfully conducted with a total of 26 participants.

The current water and energy crisis has brought about a major change in many aspects of the water industry. The shift towards a true urban water cycle, both at local and regional scale, poses numerous challenges and opportunities for the water industry as a whole.

The AWMC research portfolio consists of seven linked programs, shown below. The combined efforts of these programs are achieving sustainable outcomes for the water industry, protecting our water resources and critical infrastructure.

The following pages takes a look at the each of the programs and the outcomes for 2010.

Water Recycling

In 2010, the Water Recycling Research Program has extended its collaboration with the SEQ Urban Water Security Research Alliance, a partnership between the Queensland Government, CSIRO, The University of Queensland (UQ) and Griffith University.

• In the context of source control we investigate which fractions of the total load of pharmaceutical residues in the influent of a sewage treatment plant or advanced water treatment plant originate from hospitals using modelling and experimental evaluations,

• With regard to advanced water treatment of municipally treated wastewater, we are looking at alternatives technologies to current microfiltration and reverse osmosis processes such as biological activated carbon and ozonation for the production of recycled water;

• In relation to the production of drinking water, we investigate the occurrence of regulated and emerging disinfection by products may be of concern for SEQ.

UQ, WaterSecure and Veolia Water continue their strategic collaboration with projects on:

• Membrane fouling, chemically induced ageing of membrane in RO technologies and integrity in membrane filtration of secondary effluents.

• Treatment and management of RO concentrate.• Strategies to control the formation of disinfection by

products during the production of PRW.

In the framework of the research program “Cities as Water Supply Catchments” ($13.5M) led by Monash University and supported by the National Water Commission, Victoria Smart Water Fund and various industry partners across Australia, AWMC researchers are looking at resolving issues related to safe harvesting of general urban stormwater for both potable and non-potable uses at household, streetscape, and neighbourhood scale.

Membrane Technologies for Advanced Water Treatment

Membrane technologies generally take an integral part in advanced water treatment schemes for the production of high quality water for recycling in a range of applications including industrial, agricultural and drinking water supply uses. Indeed, systems combining microfiltration and reverse osmosis membranes have successfully been implemented to produce purified recycled water. However, due to environmental and economical drivers, optimisation of these technologies is still necessary.

As part of the strategic collaboration between UQ, WaterSecure and Veolia Water Australia, we are actively working on membrane technologies with projects investigating:

• Impact of source water on membrane fouling in microfiltration and reverse osmosis membranes,

• Impact of fouling control chemicals on reverse osmosis membranes performance and ageing,

• Virus surrogates for the assessment of reverse osmosis membranes integrity,

• Reverse osmosis membranes rejection of DBPs and micro-pollutants.

In 2008, the Water Recycling Program was launched in a context of severe drought. This resulted in A$2.5 Billion water reclamation project to broaden sources of water supply. The implementation of the largest recycled water scheme in the southern hemisphere has provided a unique opportunity for the AWMC to develop cutting edge research on water recycling processes optimisation and alternative technologies evaluation, monitoring and management of emerging contaminants and improved strategies for sustainable purified recycled water (PRW) quality.


Stormwater and Human Health Risk

Stormwater has been seen as a viable alternative water resource for different end uses.

Stormwater contains a wide range of chemicals as well as pathogens, some of which may be harmful to public health. Major impediments to stormwater harvesting and use include a lack of public acceptance and clear regulatory guidance related to a number of chemicals and pathogens that may be present in stormwater prior to its use.

To establish stormwater as a viable alternative source water, research is required to:

• Identify potential pollutants that may be present in stormwater and

• Characterise the associated risk based on exposure.

We, along with CSIRO Land and Water and Griffith University are investigating chemical/pathogens and human health risk associated with stormwater which is a part of project Cities as a Catchment for Water Supply. Other partners involved in this research project include Monash University, University of Melbourne, and AECOM sponsored by many industry partners.

Disinfection By-products in South East Queensland

Disinfectants, such as chlorine or chloramines, are powerful oxidants that oxidize the natural organic matter and anthropogenic contaminants present in waters. During this process, disinfection by-products (DBPs) may be generated.

Since 2008 we have been investigating the formation of nitrogenous DBPs, such as nitrosamines, in recycled water.

This year, the research on DBPs has been extended to investigate regulated and emerging DBPs not only in recycled water but also in drinking water.

• First, our ongoing collaboration with WaterSecure and Veolia has been leveraged by the USA funded agency Water Reuse Research Foundation to investigate the occurrence and fate of regulated and emerging DBPs during the production of PRW.

• Second, a new project funded by the SEQ Urban Water Security Research Alliance in collaboration with Griffith University, Seqwater, Queensland Department of Environment and Resource Management, LinkWater and Queensland Health aims to understand which emerging and regulated DBPs are generated during the production and distribution of drinking water in South East Queensland.

(B)ESs use whole-cell biocatalysts to drive oxidation and reduction reactions at solid-state electrodes. Due to the separation between the oxidation and reduction reactions, a large range of applications is possible in the context of water and energy recovery. The most widespread application is presently the microbial fuel cell, which aims to generate power from wastewater. More recently microbial electrolysis cells have emerged. These have notably expanded the range of applications of (B)ESs, particularly towards bioproduction.


(Bio)Electrochemical Systems

Calcium Abatement in Wastewater Systems

While improved water efficiency decreases water usage, it also leads to increased ionic concentrations. For example in the pulp and paper industry, calcium accumulation causes expensive scaling. We are developing a bioelectrochemical system that generates caustic soda. This product is used for an up-stream calcium precipitation unit and on-site paper bleaching. This can help meet the demands of a smaller volume of process water without the economic and environmental cost of purchasing caustic soda.

Microbial Electrosynthesis

Microbial electrosynthesis is a novel process in which microorganisms are using electricity as their energy source for synthesis reactions. Indeed, electrical current can drive microbial metabolism, instead of more conventionally organic substrate derived from crops. As a result, it is possible to produce biofuels and biochemicals starting from CO2 or substrate organics, and electricity. The electricity in turn can be derived from wastewater treatment, or a different sustainable source of electrical energy.

Microbial Ecology of Engineered Environments

Engineered systems such as anaerobic digesters (ADs) and bioelectrochemical systems (BESs) perform a wide-range of functions, including wastewater clean-up, power delivery, and generation of useful products. Microbial communities are critical to the functioning of these systems but are poorly understood from a phylogenetic and a functional perspective. We are using a range of techniques including pyrotag sequencing, metagenomics and metatranscriptomics to link the genetic and taxonomic diversity to the overall community functionality.

Mediated Electron Transfer to Modify Fermentation Pathways

Fermentation is a key biotechnology process extensively used to produce a wide range of potential products from primary substrates such as sugars and amino acids via anaerobic oxidation or electron neutral catabolic reactions. Notably, fermentations can be significantly affected by the redox conditions of the surrounding environment. This research project is focused on studying how an electrode can produce a shift in fermentation pathways towards more attractive end-products by inducing modifications on the redox environment using different redox mediators.

Ferric Sludge Recovery

Ferric chloride (FeCl3) is commonly used in many treatment plants in order to improve the precipitation of phosphate in the water. This generates a sludge that not only has no significant value at the moment, but brings with it a high disposal cost and environmental footprint problems. The formed chemical sludge is potentially the source of valuable compounds such as iron and phosphate. A novel 2-stage process approach is being developed in which first, the phosphate is released in solution after the addition of a sulphide solution and second, an electrochemical reaction with oxidation of sulphide to sulphur on the anode enables the recovery of iron.

Bioelectrochemical Transformation and Degradation of Recalcitrant Organic Pollutants from Wastewater

The removal of recalcitrant organic pollutants such as textile dyes, agro-chemicals or pharmaceuticals from wastewater is crucial for environmental and human health protection. The AWMC (B)ES group has developed an innovative and

versatile process for the treatment of such recalcitrant pollutants from wastewater using the powerful oxidation and reduction capabilities in BES. The concept is that wastewater needs to be first treated at the abiotic or biotic cathode (reduction) to improve its biodegradability, followed by biological oxidation of the remaining products at the anode of the BES. One or both of the oxidation/reduction reactions in the two chambers of the BES can be catalysed by bacteria to help reduce over-potentials and power consumption. The electrons released from the oxidation step at the bioanode can be utilised to reduce the recalcitrant organic pollutants at the cathode, hence eliminating the need for any co-substrates.

Electrochemical Sulfide Removal from Sewers

Sewer corrosion caused by hydrogen sulfide generation is a major issue in sewer management. Existing strategies are expensive, complex and often come with drawbacks such as the loss of organic matter. We propose a novel method, in which sulfide is removed electrochemically by means of in situ generated oxygen. Due to its ease of operation and lack of peripherals this electrochemical approach is expected to exhibit important advantages compared to existing technologies.

Sulfide Recovery from Wastewater

An electrochemical process has been developed to recover sulfide from wastewater through a two-phase system, in which the anode and cathode are switched over periodically to collect a concentrated sulfide or polysulfide solution. In the first phase, sulfide is anodically oxidized and precipitated as elemental sulfur, which is then cathodically reduced and collected as a concentrated stream of sulfide or polysulfide in the second phase. Investigations are underway to apply this novel process to wastewater from a gelatin processing plant, in collaboration with Gelita Australia Pty Ltd.

Treatment of Reverse Osmosis Concentrates

Electrochemical treatment appears an attractive option for the removal of trace contaminants from reverse osmosis concentrates (ROC). Key reasons for this are the high conductivity of the ROC (limiting energy requirement) and the replacement of oxidants by electrical current. We are investigating the influence of electrode material and operational strategy on the removal effectiveness, with a particular focus on decreasing the overall toxicity and increasing the biodegradability of the trace contaminants.

Greenhouse Gases


Water and wastewater systems contribute to greenhouse gas (GHG) emissions through both energy consumption (indirect emissions of CO2) and emissions of fugitive gases such as nitrous oxide (N2O) and methane (CH4) (direct emissions). Methane and N2O are two potent greenhouse gases with global warming potentials 25 and 310 times, respectively, that of CO2 on a 100-year horizon. Their contributions to total net anthropogenic radiative forcing are very significant, at 30% and 10%, respectively.

AWMC has been directly addressing issues of GHG in the water industry since 2007 and indirectly long before this. Our greenhouse gas research program focuses on the understanding and mitigation of CH4 and N2O emissions from wastewater collection and treatment systems, as well as from receiving waters and water storages. The current research includes fundamental research with ARC Discovery grants as well as applied research in collaboration with industry through ARC Linkage projects aimed at the understanding, quantification and mitigation of GHG emissions. Our industry partners in these projects are Water Corporation, Seqwater and Healthy Waterways.

Recent and on-going projects 1. Nitrous oxide and methane emissions from South

East Queensland waterways; 2. Understanding and mitigating nitrous oxide emission

from wastewater treatment plants; 3. Understanding fugitive greenhouse gas emissions

from wastewater systems for reliable accounting and effective mitigation;

4. Direct methane and nitrous oxide emissions from full-scale wastewater treatment systems;

5. Fugitive greenhouse gas emissions from wastewater systems;

Nitrous oxide (N2O) Production from Wastewater Treatment Systems

The release of fugitive nitrous oxide from wastewater handling is a problem recognised globally. N2O is not only a potent greenhouse gas but also the single most important ozone depleting substance in the 21st century. Due to the highly dynamic conditions in wastewater treatment plants (WWTPs), N2O emission profiles are highly variable and difficult to measure. The AWMC GHG group is attempting to capture online emission profiles from full-scale WWTPs. This project is in collaboration with Water Corporation with the first online infrared N2O analyser in Australia installed in the Woodman Point WWTP, WA. An intensive sampling campaign aimed at establishing nitrogen balance and identifying conditions responsible for elevated N2O levels will be carried out in early 2011. The measurement program will then be rolled out to additional WWTPs.

In parallel to field studies, comprehensive lab studies have been carried out to understand key nitrogen transformation reactions leading to N2O production. Lab scale reactors are being used to test specific process conditions such as pH, free nitrous acid, free ammonia and dissolved oxygen concentrations on enriched cultures. Key findings to date from these studies include:

• pH has been shown to have a direct effect on the magnitude and mechanism of N2O production by nitrifying cultures.

• pH indirectly affects the concentrations of free nitrous acid that has been demonstrated to be a true inhibitor of N2O reductase activity of denitrifying bacteria, eventually leading to N2O emission.

Further development of fundamental understanding combined with field data will assist development of mitigation strategies to minimize N2O production and emission in wastewater treatment systems.

Climate change caused by greenhouse gas (GHG) emissions is one of the major challenges facing mankind today. Substantial reductions in GHG emissions are inevitable and an essential shared responsibility for all sectors.

Methane (CH4) Production from Wastewater Collection Systems

Recent field studies carried out both in Australia and elsewhere showed that a significant amount of CH4 is formed in sewers, particularly in rising mains. Significant CH4 production and emission from wastewater collection systems can be a major source of fugitive greenhouse gas. The research is undertaken through a multi-disciplinary systematic approach by integrating process engineering, microbiology, biochemistry, and mathematical modelling. Experimental investigations comprise macro-level studies on full-scale and laboratory-scale systems, to micro-level investigations on biofilm and sediments, and further to molecular-level studies on microbial communities and their activities.

Progress to Date:

• Field study conducted by the GHG team revealed that CH4 emission from sewers contributes significantly to GHG emissions from wastewater systems;

• A mechanistic model characterising CH4 in rising main sewers has been developed by our research team;

• Laboratory and field tests have shown that several sulfide control strategies can significantly reduce methane formation as a side-effect.

The study of methane formation, emission and control in sewers is still in its early stages. In the future, the GHG team will work on the following knowledge and technology gaps:

• Identification of key sources and sinks of methane in gravity sewers, particularly in sewer sediments;

• Development of a model predicting the generation, oxidation and emissions of methane under different sewer conditions;

• Development of cost-effective methane mitigation strategies.

Fugitive Greenhouse Gas Emission from Receiving Waters

Natural waterways can be a significant source of N2O and CH4. Microorganisms in sediments and in the water column can produce or consume N2O or CH4 while converting carbon and nitrogen compounds. However, there is currently a lack of quantitative data for CH4 and N2O emissions from South East Queensland waterways. The GHG team, in collaboration with Seqwater and Healthy Waterways, is monitoring the emissions of these gases from selected South East Queensland dams, estuaries and bays.

Key findings to date from this project include:

• Elevated N2O and CH4 concentrations have been found in two bays (Bramble Bay and Deception Bay) and in the Brisbane estuary, indicating all these sites are sources of greenhouse gases. The concentrations of both N2O and CH4 varied spatially at all sites measured.

• Data obtained by this project and by a parallel investigation by Seqwater showed high CH4 concentrations in the deeper water layers of the two dams (Wivenhoe Dam and Little Nerang Dam). The mean CH4 flux from Wivenhoe Dam was at least two orders of magnitude lower than emissions from Little Nerang Dam. High spatial and temporal variability in CH4 emissions was found in both dams.

Microbial Ecology

What’s Important for Formation of Aerobic Granules?

Aerobic granular activated sludge is an innovative technology the AWMC are adapting for the treatment of domestic wastewater. Aerobic granules have much superior settling capabilities in comparison to floccular sludge. This research is optimising the operation of sequencing batch reactors for aerobic granules. In an interesting discovery we find that a slow wastewater feed rate to the reactor causes loosely structured aggregates to form, rather than the desired densely packed granules. We hypothesise this due to differences in the microorganisms kinetic affinity for the wastewater substrates. Currently we are determining differences in the microbial communities and their function by analysing the protein and gene expression of these two granule types.

Evaluating Microbial Species and Function in Anaerobic Digestion

Temperature phased anaerobic digestion (TPAD), is a microbial process that has great potential for treatment of biosolids due to its high energy recovery, lower sludge production, cost effectiveness and low environmental effect. This research, funded through the Environmental Biotechnology CRC, examines the microorganisms active in the thermal pretreatment stage of a two stage anaerobic digester, to provide key conceptual insight of this hydrolysis-fermentation step. Two functionally different laboratory scale pretreatment reactors, one thermophilic (>50°C) and one mesophilic (35°C), were evaluated using 16S rRNA based molecular methods. Results indicate temperature had a significant positive correlation with the abundance of dominant ribotypes within the Thermotogeae and Firmicutes, and with enhanced hydrolytic performance. Analysis of microbial function, determined by protein detection (metaproteomics), illustrates the thermophilic sludge has a high abundance of extracellular proteins that are likely important for the enhanced hydrolytic performance of the pretreatment stage.

Molecular Characterisation of Microbial Communities Involved in Anaerobic Methane-Driven Denitrification

Anaerobic methane-driven denitrification (MDD) is a microbial process that drives the oxidisation of methane to carbon dioxide coupled to the reduction of nitrate or nitrite to dinitrogen gas. There are many obvious industrial uses for this process, however, whilst the prevalence of MDD in the environment has not yet been fully evaluated, it has potentially important implications for both the global carbon and nitrogen cycles. To date, two key groups of microorganisms have been shown to be involved in this process, a bacterium Candidatus “Methylomirabilis oxyfera” and ANME-2D-like Archaea. While “M. oxyfera” has been extensively studied, including the recent sequencing of its genome, a detailed understanding of the ANME-like Archaea is lacking. We are currently sequencing the genome of the ANME-2D-like Archaea using a novel single cell genomic approach in order to gain greater insight into how this organism carries out MDD. Additionally, we are characterising the microbial communities in several bioreactors at the AWMC that have been operated to enrich for organisms capable of carrying out MDD to identify other important microbial players involved this process.

Enhanced Biological Phosphorus Removal (EBPR) Bioreactors as a Model System for Understanding Phage-Host Dynamics

Phage (bacterial and archaeal viruses) are ubiquitous in the environment and drive the dynamics and evolution of microbial communities through predation and horizontal gene transfer. The sheer diversity of phages in natural environments makes it difficult to study phage-host interactions at the community scale. The EBPR bioreactors dominated by Candidatus “Accumulibacter phosphatis” represent an ideal controlled engineered system to monitor phages-host interactions. Further, phage predation could be responsible for dramatic collapses in EBPR performance.

Microorganisms occur in every habitat on earth, and are responsible for many of the steps in the global water cycle. At the AWMC, the microbial ecology team is attempting to understand microorganisms at every level, from genes through to ecosystems. The research uses cutting-edge molecular tools, as well as more traditional microbiological techniques, to gain fundamental knowledge and understanding of these complex, yet fascinating processes.


To analyse the mechanisms of EBPR phage-bacteria interactions we are using metagenomics to sequence whole phage communities in a lab-scale EBPR reactor. In combination with this we are using PCR to study the activity of host defence genes against phage. We have successfully developed techniques to extract and sequence the DNA of phage communities and accurately quantify viral numbers using flow cytometry. Analysis of metagenomic data from an EBPR reactor has lead to our discovery of a novel mechanism in the phage-host arms race by which phage can potentially down-regulate essential defence genes of the host. Future work will focus on analysing, in depth, the temporal aspects of phage-host interactions in EBPR.

A New Research Partner at UQ: The Australian Centre for Ecogenomics (ACE)

The Australian Centre for Ecogenomics, or ACE for short, is a new centre recently established in the School of Chemistry and Molecular Biology as part of a strategic initiative to build capacity in microbial genomics at UQ. The AWMC is a major ACE research partner and has been centrally involved in its establishment. This collaboration is further cemented by the direct involvement of Gene Tyson as Deputy Director of the new centre and return of former AWMC postdoc, Prof Phil Hugenholtz, from the Joint Genome Institute in the US to be the ACE Director. ACE has three major research themes; environmental, host-associated and tree of life. An important component of the environmental theme is engineered systems and this is the focal point of AWMC-ACE research. A key collaboration with Prof Zhiguo Yuan and Dr Shihu Hu concerns the microbiology of anaerobic methane-driven denitrification (MDD). This collaboration has already resulted in the genome sequence of an MDD organism from an AWMC bioreactor revealing key metabolic underpinnings of this process. Further information about ACE including researchers and projects can be found at www.ecogenomic.org

Sewer Corrosion & Odour Research (SCORe)

The generation of hydrogen sulfide (H2S) has long been known to be a major cause of corrosion and odour problems in sewer systems. However odour and corrosion in sewers has often been taken as a fait accompli, with sewer vents being closed if odour problems occur and the odours being vented elsewhere in the system or at the inlet to the wastewater treatment plant.

Development of fundamental scientific knowledge of sewer processes has been limited since the publication of the “Hydrogen Sulphide Control Manual” in 1989 which is still commonly used by industry for the prediction of sulfide generation in sewers.

Basic knowledge gaps still exist in our fundamental understanding of odours and corrosion including the following:

• Corrosion Processes & Control: The estimation of the corrosion rate and the life expectancy of pipes are very difficult to predict and are almost entirely based on empirical data about the past performance of pipes under similar conditions.

• Gas Phase Technologies: It is difficult to quantify and characterise odours from sewers without relying purely on costly, problematic and time consuming human olfactometry systems. In addition, applications of odour abatement systems rely on empirical data with little fundamental understanding of the processes occurring for the removal of the odour.

• Liquid Phase Technologies: A lack of understanding of the chemical and biochemical transformations that occur in wastewater and the impact of variables such as flow velocity, sediments, changes in wastewater composition. This makes it difficult to predict the impact of chemicals commonly used to control H2S in sewers such as O2, NO3

-, Mg(OH)2, FeCl3, etc. Without closing these knowledge gaps it is not possible to optimise dosing systems for the control of odours in the liquid phase or to reliably predict the impact of dosing systems on the receiving wastewater treatment plants.

There has been heightened interest in the management of odour and corrosion in sewers in recent years for a number of reasons:

1. Sewer systems are being extended to fringe populations around the major cities with ever increasing size of the collection systems and greater dependency on the pumping of sewage and hence greater generation of sulfides in the system.

2. Water restrictions and demand management of water supplies is resulting in significantly lower flows and higher concentrations of COD, sulfates and other pollutants. This then produces longer retention times in rising mains and the quicker onset of anaerobic conditions which cause generation of more H2S and to potentially higher concentrations (due to higher sulfate and/or COD concentrations).

3. Warmer climates over the last decade which lowers the solubility of oxygen, encourages the more rapid depletion of the oxygen in the wastewater and stimulates the generation of H2S by the sulfate reducing bacteria (SRB).

4. Trade waste regulations have reduced the amount of heavy metals (and other pollutants) that are discharged to sewers, which has reduced the precipitation of metal sulfides in sewers. Precipitation of the heavy metal sulfide would reduce the H2S concentration in the sewage. In addition it is believed that the heavy metals also have a inhibitory effect on the microbes responsible for H2S production.

The size of this problem is reflected in the broad support being provided to the SCORe Project by water utilities throughout Australia. There are 11 industry partners and 11 research partners. The project started in late 2008 and will run for five years with a total budget of approximately $20 million.

Optimal management of sewer systems has been hindered by a limited understanding of several key in-sewer processes, and the lack of tools and reliable technologies to support strategic decisions and cost-effective sewer operation. The value of public assets is being significantly diminished as a result of corrosion problems, with the replacement of concrete sewer pipes costing hundreds of millions of dollars yearly in Australia. This research program is delivering highly valuable outcomes for the Australian water industry.


This project brings together the scientific knowledge of world-leading researchers and the vast amount of practical expertise available in the Australian utilities, which will ensure practical outcomes based on fundamental scientific knowledge. The skills and expertise possessed by the research providers and industry partners are very diverse yet complementary, enabling the integration of process engineering, mathematical modelling, environmental chemistry, material science and microbiology, together with operational experience, in the search for solutions.

The project comprises four themes under which ten subprojects are managed:

• Theme 1 - Understanding and predicting corrosion processes

• Theme 2 - Gas phase technologies• Theme 3 - Liquid phase technologies, and• Theme 4 - Decision support and knowledge

management

Six of the ten subprojects are being carried out by the AWMC as well as the overall project leadership, project management and organisational responsibility.

Despite being operational for only two years, outcomes from the SCORe project are already having a major influence on industry partner practices and decisions which are providing significant financial benefits. Some examples include:

• Testing of some odour control chemicals has been postponed by industry partners based on outcomes from laboratory and field testing of the project.

• Control strategies developed by AWMC are being applied for optimising the dosing of proven chemicals for odour and corrosion control.

• The SeweX model is now being used by several industry partners to predict and manage odour and corrosion in their sewerage collection systems.

Bioproducts & Nutrient Removal

Next Generation BioplasticsPHA (polyhydroxyalkanoate) bioplastics are recognised as outstanding candidates to replace conventional plastics. Their mechanical properties are industrially relevant, they are produced from renewable resources, and they are truly biodegradable. Furthermore, our recent work shows that the PHA bioplastics synthesis has the capacity to utilise cheap and renewable carbon sources such as organic wastes, which are economically competitive with petroleum based alternatives.

We are teaming up with AnoxKaldnes Biopolymer of Sweden and UQ’s Centre for High Performance Polymers for an ARC funded project on using mixed microbial cultures to engineer commercial grade PHA. The aim is to advance mixed culture PHA technology by integrating state-of-the-art polymer characterisation and processing with mixed culture biopolymer production.

Our team has already successfully accumulated PHA in biomass harvested from wastewater treatment plants. We have extracted PHA from within the biomass, and have found that thermal properties and molecular weight are as desirable as those produced in mixed cultures. In the next phase of research we will be assessing the mechanical properties and rheology of our PHA, with the view of identifying markets for our bioplastic commodity.

Nutrient Recovery Helping to Improve the Sustainability of the Australian Agriculture SectorAustralia is one of the food bowls of the world, exporting approximately 50% of food produced nationally. We are also recognised as having some of the most sustainable and best managed agricultural sectors in the world. However, there are a number of issues over sustainability and pricing of mineral nutrients. Nitrogen is produced from fossil derived natural gas, while phosphate is mined from non-renewable resources. Supply issues have seen dramatic fluctuations in pricing over the last five years, particularly for phosphates. This is the driver for the Grains Research and Development Corporation to find new, sustainable sources of nutrients.

They have funded research at the AWMC to investigate recovery of nitrogen and phosphorous from waste streams. We have determined that up to 20% of the national phosphorous and nitrogen market could be supplied by recovering from waste streams, and that farm scale technology would both have a relatively rapid payback, as well as providing benefits such as renewable energy. This research is helping to provide new revenue streams to the agricultural sector, reduce environmental and greenhouse gas impact, and generate new sources for fertiliser.

Pandemic Concentrations of Pharmaceuticals in Wastewater: Effects on Nutrient RemovalThe recent H1N1 2009 influenza pandemic saw many people treated with antivirals and antibiotics. High proportions of both classes of drugs are excreted into wastewater and will eventually end up in treatment plants. There has been international concern that unprecedented levels of these pharmaceuticals in wastewater during a pandemic could have adverse effects on the bacteria in nutrient removal systems, causing decreased function. Additionally, downstream effects on aquatic life in receiving waters are unknown. Investigations have to date been mostly limited to modelling and pure culture studies.

We conducted the first assessment of the effects of pandemic-scale pharmaceutical doses on nutrient removal reactors. A laboratory-scale sequencing batch reactor was operated as an aerobic granular sludge for enhanced biological phosphorus removal (EBPR). There was little removal of antiviral compounds by the sludge, demonstrating the potential for antiviral compound contamination of receiving waters. We also recorded disruption to granule structure, to EBPR and nitrification, and to bacterial communities following high doses of antivirals and antibiotics. These findings indicate the risks of pandemic concentrations of pharmaceuticals to nutrient removal processes and highlight the need for further research. Our future investigations will look further at the mechanisms of the effects of these pharmaceuticals on bacteria responsible for nutrient removal, particularly focusing on biofilm disruption.

The AWMC has built a strong reputation in nutrient removal technologies over the last 14 years in the field. However, recent changes in the industry have given us new challenges including reducing costs, smaller treatment plants, and adding benefits to the treatment of wastewater, both domestic and industrial. This research program has met these challenges head-on, leading the world in the emergent technology of aerobic granulation systems and harnessing the potential bioproducts from wastewater.


Algae Derived BiofuelsThe depletion of oil reserves and a quest for independence from fossil fuels are driving the search for alternative fuel sources. Biofuels from microalgae is an exciting and viable option. The direct advantages of algae-derived biofuels over conventional biofuels are a very high yield per hectare and no competition for arable land. Still, algae production currently relies on the availability of low cost synthetic fertilisers. At the AWMC we are aiming to address this by investigating the potential for using waste streams as an economic and sustainable nutrient supply for algal biofuels.

Our research focus is two-fold. Firstly we are aiming to produce biogas by digesting algae grown on wastewater, and ultimately boost biogas yields by pre-treating algal biomass prior to processing. We have already shown that pre-treatment can lead to a 30% increase in biogas production. Secondly, we are developing knowledge on microbial communities in open algal systems, with the view to understanding the interactions between key populations. The outcomes will be significant in terms of tracking nitrogen and phosphorus utilisation in algal ponds when wastewater is used as the nutrient supply.

Anaerobic Technologies

Anaerobic Technology Group Overview

Anaerobic technology research is an established program within the AWMC, we think of anaerobic biotechnologies as resource recovery technology, rather than solely waste treatment processing. Anaerobic processes handle concentrated organic streams without the need for expensive aeration operations. Methane rich biogas produced during anaerobic stabilisation is a source of green, renewable energy. As a result, anaerobic biotechnologies can generate energy rather than consuming it. In addition anaerobic stabilisation can mobilise valuable nutrients stored in organic materials with excellent fertiliser potential. The combination of these factors ensures anaerobic biotechnology has a strong future within an environmentally sustainable Australia.

Anaerobic technologies may be implemented at a broad range of technology levels in a range of industries. Therefore, the AWMC has assembled a diverse research team including over 15 academic staff, process engineers, molecular scientists and higher degree research students. We work across the product development cycles, from investigation of basic relationships between microbes to construction of large demonstration plants. The knowledge we develop in the laboratory feeds directly into our full-scale implementation and consulting work.

Linkages are strong with industry, and we have large research projects across most industrial sectors, including energy, agriculture, waste/wastewater treatment and industrial biotechnology. Here we showcase a number of projects that contribute to these areas.

In 2009, motivated by fluctuations in fertiliser prices, and practical agronomic advantages of natural fertilisers, the anaerobic group broadened its research program to include nutrient capture and recovery processes. Supported by the Grains Research and Development Corporation, AWMC is assessing the use of local materials for production of a high-value organically derived mineral fertiliser. This will be a direct replacement for existing fertiliser sources, with a fraction of the environmental footprint, and with a better agronomic profile.

Waste-to-Energy Program

Our waste-to-energy program has continued to develop in recent years. The small medium biosolids stabilisation project is using temperature phased anaerobic digestion (TPAD) to achieve similar environmental and financial benefits of advanced large scale anaerobic treatment technologies with much lower capital investment. Until now advanced anaerobic digestion technologies have required huge capital investments that put them beyond the reach of many small to medium producers.

TPAD combines a relatively short thermo-biological pre-treatment with conventional anaerobic stabilisation. The pre-treatment stage stimulates the early stages of digestion resulting in significant improvements in overall stabilisation rates. These improvements in rate increase the loading rates through anaerobic processes while reducing the size and capital costs of process vessels. The sanitised final biosolid produced with elevated temperature during the pre-treatment step is a higher quality than biosolid achieved from conventional digestion and can be reused as a fertiliser product which is superior to chemical fertilisers in terms of environmental impact, cost, and plant nutrition. TPAD utilises simple infrastructure and is highly flexible for application to food processing residues, domestic sludge treatment from large municipalities to smaller communities down to 10,000 persons and other solid organic wastes. Expanding on the success of the small-medium scale biosolids project, AWMC researchers are now investigating short term thermo-biological reactors as a dedicated high rate anaerobic stabilisation technique. The development of high rate processes applicable to solids digestion is an exciting prospect.

Our waste-to-energy projects are supported by the Environmental Biotechnology Cooperative Research Centre (EBCRC), the Queensland State Government (Smart State RIPP Scheme), Meat and Livestock Australia Limited (MLA), the Australian Meat Processor Corporation (AMPC), and Australian Pork Limited (APL) within the Methane to Markets Scheme.

The anaerobic technology group works across the product development cycles, from investigation of basic relationshipsbetween microbes to construction of large demonstration plants. The knowledge developed in the laboratory feeds directly into our full-scale implementation and consulting work. Linkages are strongwith industry, and we have large research projects across most industrial sectors, including energy, agriculture, waste/wastewater treatment, and industrial biotechnology.


Small-Medium Scale Demonstration Facility

With the help of our industry partners, we are putting our research to the test. The small-medium scale biosolids demonstration plant was commissioned in 2010. Located at a red meat processing facility in South East Queensland the plant is designed to treat approximately five wet tonnes of organic waste per day. The demonstration plant is capable of processing both solid waste and wastewater streams onsite at the host plant. Biogas from the plant is used to fire an industrial water heater capable of producing over 100 MJ/hr. We are now looking at gas engines to generate electricity from the biogas.

Applying Computer Game Theory to Microbe-Microbe Interactions

Classical biological process modelling is effective but unsatisfying. We represent microbes the same way we represent chemicals such as water or sugars. That is, they are a bulk property that can increase or decrease in concentration or potency. The reality is vastly different, and as we know, microbes form biofilms, interact, predate on each other, and in other ways compete for, and share food, space, and nutrients. To properly represent this in models, we need to consider not only the microbes as individuals, but other characteristics such as size, shape, and secondary filamentous growth and motility. This is being addressed by a microbe-lagrangian modelling project, or modelling microbes as individuals. This not only considers chemical characteristics of the microbes, but also uses basic physics to describe how they interact on a physical level. For concepts such as collision detection and response, concepts from computer game programming are used, and we are finding that basic structural components such as microbe elasticity and strength can have a profound impact on the appearance of a simulated biofilm. In fact, some very complex biofilm characteristic can be explained by basic physics rules. The next phase will allow us to include cell physical structures such as bound proteins, and modelling of chemical interactions between cells.

Giving Bugs a Close Shave

A new research project is looking at how microbes function in naturally forming bio-granules. Granular biomass forms naturally in high-rate industrial anaerobic treatment systems. It is highly important for treatment systems such as used at Foster’s Brewery in Yatala, and Trisco Foods in Carole Park, both of whom have strong links to the AWMC. Yang (Kenn) Lu, an EBCRC PhD student at the AWMC is looking at a primary component in these granules, the microbes which break down complex organics. He has found that they mainly exist on the surface of the granule, and is now using new techniques to progressively shear layers from the granule, and analyse these separately from the parent granule. While the immediate goal is investigation of the structure of the granules, in the future we want to enhance their capability. This will allow us to further improve existing treatment systems, while expanding their application to more difficult wastewaters such as meat processing, intensive agriculture, and even domestic sewage, offering more sustainable, and lower cost wastewater treatment. The project is funded by the Environmental Biotechnology CRC. In the initial UQ-EBCRC project, we found microbes that were much better at breaking down the organic materials in sewage sludge. Now we want to make these microbes work in advanced, high-rate applications. This is a truly new technology that offers compelling advantages against existing competitors.
