Existing anaerobic-aerobic treatment plants have a great potential to maximize their performance and life expectancy. With the Nijhuis AecomixTM, a simple retrofit solution, more waste and wastewater will turn into valuable products.

The compact and modular design of the AecomixTM DGF units can easily be situated and integrated into existing anaerobic-aerobic treatment plants, ensuring a higher solid retention at the existing anaerobic reactors compared to original situations. This will result in a higher capacity of the reactor, more biogas and reduce the OPEX of the aerobic treatment.

In cases where wastewater is discharged to the sewer, discharge costs would be reduced. In cases where a polishing step is required, the solid and biological loading in aerobic polishing treatment steps would be significantly reduced. This results in lower energy and chemical consumptions for the aerobic process, reduced sludge production and reduced disposal costs.

The DGF is a unique flotation technology which is not sensitive to solid waste. The anaerobic treatment plant can handle larger wastewater volumes and also other, non-water related, organic waste streams. In summary, the Nijhuis AecomixTM is a robust retrofit solution to maximize the performance and lifetime of existing anaerobic-aerobic treatment plants to receive more biogas and reduce OPEX.

NIJHUIS AMMONIA RECOVERY: FROM BIOLOGICAL OXIDATION TO RESOURCE RECOVERY, MAXIMIZING THE VALUE OF DIGESTATE

4

Today’s challenges in the marketWaste treatment facilities for digestate and manure are facing multiple challenges, especially when high ammonia concentrations occur in the feedstock, resulting in a number of technical challenges:

1. Decrease in biogas production due to ammonia inhibition. Anaerobic digestion is sensitive to high N concentration and can be a major problem for a biogas plant, treating digestate, manure or sludge.

2. High discharge cost after the dewatering of digestate or manure, because of high N concentrations in the centrate water and environmental pollution.

3. High CAPEX and OPEX, when aerobic treatment is required to purify the centrate water. The reduction of the COD during anaerobic digestion often results in a COD/N ratio which is too low for further aerobic nitrogen removal. Conventionally, an additional dosing of a carbon source is used to optimize the ratio.

These challenges are faced by ‘green field’ or existing digestion plants. Customers are anxiously searching for a robust, proven, cost effective and fit for purpose solution to optimize their plant and maximize the value of their digestate.

The NAR system is a true game changing innovation with a ROI based on the ammonia concentrations in the feedstock to: lower substrate costs, heighten the TSS/COD load in the digester, enhance biogas income (reduction of N toxicity), save on additional biological treatment cost, lower the discharge cost and produce a valuable product and a biobased fertilizer (up to 120 euro / ton varies per geographical location).

Maximizing the value of digestateSeveral technologies claim effective removal of ammonia from digestate. However, all of these technologies consume a lot of energy and only oxidize the ammonia, without creating a valuable product. By removing ammonia, the treated water can be used for diluting the substrate to enable more co substrates, lowering the ammonium concentration of the substrate or improving COD/N ratio of the centrate water. The NAR is an innovative and stable process which is anticipating today’s challenges in the market and producing ammonium sulphate, to maximize the value of digestate. The market potential for this biobased fertilizer varies per geographical location, but proves to be commercially very attractive.

How is the system being applied?The NAR is a proprietary chemical process based on the stripping of ammonia. The process is designed to treat digestate, or manure, and consists of a heat exchanger, a CO

2 stripper tank, an ammonia stripper and a scrubber. In order to prevent clogging of the stripping column, pre-

treatment of the digestate such as a cloth screen, screw press or centrifuge is required. In the CO2 stripper tank the liquid is heated up and fresh

air is injected in to the liquid to strip CO2. A heat exchanger on the effluent flow reduces the heat requirement of the system.

Why Nijhuis Ammonia Recovery?The Nijhuis mission with this next level of ammonia recovery is ‘doing more with less’. The NAR has a proven ammonia removal efficiency of 80-90%, with the lowest energy consumption. Dilution of the substrate creates a higher biogas production by minimizing toxicity. Less additional co-substrates are required to mix the high ammonia substrates. Depending on the liquid digestate disposal, the NAR system will lower

the discharge cost. In the case of additional biological treatment no additional carbon source is required, therefore less energy is required, which results in huge savings on OPEX and CAPEX. Finally the stripped ammonia is recovered as ammonium sulphate which requires no oxidation of the ammonia and can be sold as a biobased fertilizer.

THE NIJHUIS

AMMONIA

RECOVERY

The Nijhuis Ammonia Recovery system has been delivered to Bernard Matthews in Holton, one of the leading turkey processing companies in the United Kingdom to address their digestate treatment requirements and to turn their (waste)water facility into a resource recovery solution. The customer has been facing high nitrogen concentrations in the feedstock entering the anaerobic treatment system. After having installed a Nijhuis pre-treatment and biological treatment system for the wastewater the customer wanted to generate energy with their digestate. Soon after the anaerobic treatment installation was up and running, Nijhuis has been challenged to deal with the high N in the feedstock.

System configuration and solutionThe decanter centrifuge is dewatering the digestate coming out of the digester into a liquid and cake fraction. As the cake will be discharged, the liquid fraction (centrate water) will enter a heat exchanger, resulting in stripping the ammonia under high temperature. The ammonia gas is treated by the Nijhuis Ammonia Recovery system which ensures a biobased fertilizer. The improved COD/N ratio of the centrate water out of the NAR results in OPEX savings on the additional biological treatment of the water.

Results After installing the system, the NAR has been optimized in order to meet the optimal process settings, process stability and the removal efficiency for NH

4-N, removing more than 80% of total nitrogen. The ammonia removal and recovery system would not only prevent this inhibition and

increase biogas production but also recover the valuable nutrient nitrogen. Results have shown that ammonium sulphate can be produced at any desirable concentration between 25-40%, turning the Nijhuis Ammonia Recovery system into a true waste to value solution.

NIJHUIS AROUND THE WORLD

Last year, Nijhuis won the contract for a large turnkey project for the delivery of a new wastewater treatment plant. Azomures is the largest fertilizer producer in Romania, and one of the largest fertilizer producers in Europe. Nijhuis Industries has been appointed as EPC contractor for the turnkey delivery and is currently executing the civil works on site. The basic engineering has been executed together with Dutch based Engineering Consultant Witteveen+Bos.

Besides their Dutch partner a number of first class Romanian partners are involved in detailed engineering, permitting, civil works and the mechanical and electrical installation. As main contractor, Nijhuis Industries is responsible the full turnkey installation on site, including all permits and supporting documentation until the final acceptance test.

This acceptance test will confirm the stringent effluent characteristics are being met. The new WWTP will treat all wastewater from Azomures, with an average volumetric capacity of 22,500 m3 wastewater per day. One of the drivers behind this large investment is the ever demanding effluent parameters to be met by Azomures in 2016. The total project, consisting of the modernization of the urea and ammonia installation as well as the wastewater treatment, will be one of the largest and most advanced plants ever built in Romania. Last May, the senior management team at Azomures, and local Romanian press representatives, visited both the Nijhuis Industries headquarters in Doetinchem and one of the advanced wastewater treatment plants delivered by Nijhuis in Poland.

Nijhuis is part of a consortium that has been successfully awarded the contract to deliver a fully integrated wastewater and sanitation solution for three municipalities in the Accra region of Ghana. The project will be realized together with several NGO’s and private companies in both the Netherlands and Ghana. Also public toilets will be constructed and a collection infrastructure put in place to deliver faecal sludge to three different treatment locations in the municipalities of Nsawam, GA West and GA Central. In total they will have the capacity to process the faecal sludge of 300,000 people including the population of 8,000 people of the Nsawam’s Security Prison.

The consortium successfully managed to obtain a grant from the Dutch Government through the WASH Window program. The grant is obtained by presenting a highly esteemed business plan to the evaluation commission of RVO. The business plan is the result of a year of hard work and close cooperation between Gieling Consultancy, MDF in Holland and Ghana, Nijhuis and local contractors along with the Dutch Embassy and the three local mayors of the municipalities. The business plan was awarded as the best Dutch business plan out of a total of 22 initial plans submitted.

Nijhuis will design, build, operate and maintain the three wastewater treatment plants in the period between 2015 to the end of 2019. The water will be used for agricultural applications and the sludges will be

used for biogas production in locally built digesters. The digested sludge will be composted and sold as fertilizer. The treated water will be applied for agricultural and industrial use.

The Special Treat Project is offering a three step integrated wastewater value chain consisting of a filtration step, physical / chemical treatment and biological treatment by double SBR. The prison and public toilet blocks will provide the faecal sludge and will mix with faecal sludge from households, hotels and enclosed compounds and be collected by trucks. The aim of the project is to divert the sludge, which is currently discharged into the sea at Lavender Hill, to three different treatment locations securing a healthier and safer environment.

Nijhuis Industries Central Europe (NICE) successfully delivered an innovative and compact system for Biovast, a leading producer of animal by-products. The company is part of ARVI, a Lithuanian Group which specializes in the production of fertilizers, animal food, sugar, meat processing and various by-products, with production plants located in Central and Eastern Europe.

Biovast has upgraded the animal by-product processing plant to process 40 - 50.000 tons of animal by-products per year, increasing their annual capacity over 10 times. The customer wanted to build a new, modern wastewater treatment plant to meet the environmental requirements that allows treated wastewater to be discharged to the river. The system had to meet discharge quality and minimize the environmental impact and footprint, while ensuring fast execution on site.

The installation was designed to treat 40 m3/day of highly polluted rendering wastewater.

The system consists of a filter, flocculation, flotation, a continuous biology, a dewatering step and two modular containers. The Nijhuis added value services covered installation, commissioning, start-up and service visits. To meet their requirements Biovast opted for a concrete biological tank and two containerized systems which simplified the transportation and minimized the installation works on site.

The containers were designed and executed to fit to the system requirements and provide an innovative ‘plug-and-play’ solution. The process equipment (filtration, flotation and sludge dewatering) was installed in one container. The remaining equipment including Nijhuis control panel and chemical dosing stations were mounted in the second unit.

After completion and commissioning in Q4 2014, the system has proven to be reliable, effective and easy to maintain, meeting all of Biovast’s requirements.

AUTOMATIC TUBE CLEANING: MAXIMIZE HEAT EXCHANGER PERFORMANCES AND EXTEND LIFETIME

WITH LOW OPERATIONAL COSTS

Air conditioning systems and industrial processes use heat exchangers for cooling purposes of their process water or gas. Water based cooling systems suffer from fouling of the tubes of the heat exchangers leading to a reduction in efficiency and increased power consumption, and consequently higher operating cost. Heat exchangers are considered to be one of the largest power consumers in power, food & beverage, chemical, oil & gas and pulp & paper plants. In cases where surface water is used as cooling medium the Nijhuis Automatic Tube Cleaning system is the ultimate solution to keep the installation in optimal condition and at the lowest possible costs.

The intake water will significantly reduce the efficiency of the heat exchanger because of the fouling and scaling in the water. Research indicates that a fouling layer of only 0.6 mm on heat exchanger tubes reduces the heat transfer efficiency by 34% and increases the power consumption by 21%. Conventional methods like the dosing of chemicals fail to fulfill sustainability and economical goals. Regular manual cleaning requires shut down of the process for some days and biofouling will start to build up with immediate effect. The Automatic Tube Cleaning works continuously without interrupting the processes.

Why Nijhuis Automatic Tube Cleaning?The Nijhuis Tube Cleaning system is a unique technology to help customers meet increasingly demanding sustainability requirements. This technology is a simple, robust, chemical free and environment friendly solution to keep heat exchangers working at full capacity, maximizing effective lifetime with the lowest operational costs.

Application and working of the system The Nijhuis Automatic Tube Cleaning system comprises a unique Nijhuis 4 way flow diverter and a Nijhuis cleaning set of one brush and two baskets for each tube of the heat exchanger. The flow diverter is positioned in the piping to and from the heat exchanger. It is custom designed for various piping configurations for ease of installation and a pressure drop lower than 0.2 bar. This unique flow diverter allows for periodic flow reversal through the heat exchanger at pre-set times, without reducing or stopping the flow through the heat exchanger and without taking the heat exchanger out of service or interrupting its operation.

The Nijhuis Automatic Tube Cleaning system is designed to comply with the specific local aspects such as water flow, water quality, diameter connection of the heat exchanger and the number of tubes. The system is installed as an integral part of the heat exchanger. The Nijhuis Automatic Tube Cleaning system provides a permanent solution to combat scaling and fouling problems by reducing power consumption, minimizing shut downs and maintenance costs.
