ENERGY RECOVERY FROM WASTEWATER SLUDGEThe waterleau technology portfolio includes a range of anaerobic reactors to recover biogas from sludge digestion. Up to 70% of the power needs of sewage treatment plants can be produced from the available sludge. In order to limit the digested sludge volume, our solar and thermal drying or even sludge incineration technology will reduce or limit to near zero the sewage treatment by-product.

BIOLOGICAL WASTEWATER TREATMENT

BIOTIM® ACTIVATED SLUDGE WASTEWATER TREATMENTThe BIOTIM® Activated Sludge Wastewater treatment system is Waterleau’s conventional aerobic sewage treatment technology including every treatment step in an integrated and turn-key biological wastewater treatment system: from coarse screening at the water intake to tertiary treatment and reuse of the purified water.

In the BIOTIM® Activated Sludge Wastewater treatment design, the accumulation and regeneration phase of the biological treatment process take place in an activated sludge reactor tank connected to a separated sedimentation tank. In contrast, in our LUCAS® Municipal compact design, the three phases of biological treatment are alternated in a series of identical tanks, each capable of performing accumulation, regeneration and sedimentation.

BIOLOGICAL WASTEWATER TREATMENT

LUCAS® MOVING BED BIO REACTOR (MBBR)The LUCAS® Moving Bed Bioreactor (MBBR) is a biofilm variation of the activated sludge wastewater treatment process and Waterleau’s solution for the treatment of high-strength wastewater, or for situations where the available treatment plot size is limited. Implementing MMBR in existing plants is a cost-effective way to increase both capacity as well as effluent quality without additional footprint expansion.

In the LUCAS® Moving Bed Bioreactor, the biological treatment process is stimulated by introducing a more robust microbial environment to breakdown the nutrients. A moving media, typically a floating plastic substrate colonized by a community of bacteria (biofilm) is introduced in the reactor. These bio-carriers circulate with the aeration in a random motion, ensuring excellent oxygen and substrate transfer to the biomass, enhancing biological nitrogen removal, and improving effluent quality.

FEATURES

� Polyethylene carriers with biofilm circulate in reactor tank

� Type of bio-carrier depends on influent and plant design

� Oxygen and circulation by diffused or jet aeration

� Screens prevent media carriers from flowing out of tank

ADVANTAGES

� Higher specific activity allows smaller tanks

� Increase capacity of existing plants

� Multiple MBBR with different carriers for specific treatment

� Filling degree of carriers adjustable

� Biofilm reactors or hybrid reactors

� A combination with BIOTIM® and LUCAS® designs

LUCAS® Moving Bed Bio Reactor: accumulation and regeneration

efficiency increased by use of bio-carriers. Sedimentation by lamella

settles limiting footprint.

ATLANTIS® MEMBRANE BIO REACTOR (MBR)The ATLANTIS® MBR is Waterleau’s Membrane Bio Reactor technology. Since the ATLANTIS® MBR technology membrane filtration will cover biological treatment and filtration in one single step, the high-quality effluent can be used directly as service water or for irrigation. The ATLANTIS® MBR technology is well-suited for retrofitting, capacity expansion and enhanced elimination performance of existing wastewater treatment facilities.

In an ATLANTIS® MBR, submerged hollow fiber membranes seperate sludge from the biologically purified wastewater. The membranes in the bioreactor are kept clean by means of an efficient coarse bubble aeration, which ensures a good sludge management in the membrane module and guarantees turbulent conditions at the membrane surface.

FEATURES & ADVANTAGES

� Submerged membrane modules installed in bioreactor

� Transmembrane pressure filters clean water from activated sludge

� Biological cleaning and filtration in one single system

� Higher efficiency for elimination of micro pollutants

� Filtrate free of suspended solids and bacteria, ready for re-use

� Very compact installation

� Increase treatment capacity in existing plants

KROFTA® DISSOLVED AIR FLOTATION (DAF)In the municipal and industrial wastewater treatment process, Krofta® DAF technology is often integrated as a high-performance technology for solid-liquid separation in the pre-treatment step as well as for post-treatment polishing. Krofta® Sandfloat DAF technology is particularly adapted for drinking water production.

Known the world over for unparalleled liquid-solid separation solutions, Krofta® DAF systems combine innovation with time-tested separation technology. Whether you require a circular, rectangular design, or an integrated system that combines flocculation, flotation and filtration in one single unit, our Krofta® DAF liquid solid separation technology creates highly efficient separation and an effluent with low concentration of suspended solids.

ENERGY RECOVERY FROM SLUDGE

BIOTIM® SOLIDSThe organic matter of sludge contains energy that can be recovered. Up to 70% of the energy needs of a wastewater treatment plant can be provided by sludge digestion. The methane generation is a key advantage of the anaerobic digestion process of wastewater sludge. The methane can be used in co-generators for producing heat and electricity. BIOTIM® AD Anaerobic Digestion technology is Waterleau’ solution for energy recovery, the reduction of the treatment plant’s carbon footprint and greenhouse gas emissions.

ADVANTAGES

� Recovery of up to 70% of energy needs from sludge

� Reduction of carbon footprint and greenhouse gas emissions

� Reduction of sludge volume and sludge handling cost

AIR TREATMENT

BELAIR® ODOR TREATMENTUnpleasant odors may cause discomfort in the surroundings of a sewage treatment plant. Waterleau’s BELAIR® technology makes use of biological oxidation processes for the absorption of nitrogen and sulphur-based compounds.

ADVANTAGES

� Biological process

� High efficiency of odor and VOC destruction

� No chemicals required

� Low operating cost

� Proven technology

BELGAS® BIOGAS TREATMENTUntreated biogas contains high levels of sulphur, which can be damaging for combustion engines. Waterleau’s BELGAS® scrubber technology is a simple, reliable and high-capacity technology for the desulphurisation of extraction and biogas. The BELGAS® scrubber technology reduces the amount of H2S gases using the activated sludge from the wastewater treatment process as a washing liquid.

ADVANTAGES

� Biological process

� Use of available sludge

� No chemicals required
