ANAEROBIC DIGESTION ENERGY RECOVERY FROM BIO EFFLUENT, SLUDGE AND MIXED ORGANIC WASTE ENERGY RECOVERY FROM BIO EFFLUENT, SLUDGE AND MIXED ORGANIC WASTE New Energy production is one of the four key businesses of Waterleau, next to water, air and waste treatment. Waterleau has acquired substantial know-how in the production of green energy from both organic and non-organic waste. Biogas from organic waste is obtained through anaerobic digestion, a series of processes in which micro organisms break down biodegradable material in the absence of oxygen hence producing biogas, a valuable energy source NEW ENERGY from wastewater from biomass from waste aerobic wwt anaerobic wwt anaerobic digestion drying non toxic toxic biogas biogas combustion recover & recycle biogas SOLUTIONS FOR GREEN ENERGY Waterleau offers the complete range of anaerobic digestion technology, both wet anaerobic digestion (BIOTIM® WET AD) as dry anaerobic digestion (BIOTIM® DRY AD). For wet anaerobic technology WATERLEAU offers as wel thermophilic (BIOTIM® WET AD thermophilic) as mesophilic turnkey solutions (BIOTIM® WET AD mesophilic). The Waterleau BIOTIM® and LUCAS® reactor range includes solutions for the production of green energy from every concentration of organic waste and load: Wastewater from food & beverage industry Concentrates from agro & food processing industry Sludge from municipal wastewater Bio waste Liquid and dewatered manure and chicken litter Slaughterhouse waste Energy crops; maize and grass silage Kitchen and restaurant waste (KRW) Organic fraction of municipal solid waste (OFMSW) Mixed bio waste 2 WATERLEAU ANAEROBIC REACTOR RANGE The appropriate choice of the anaerobic reactor type depends on the composition of the organic waste. Choosing the appropriate anaerobic reactor for a specific organic effluent or organic waste is a key to success. BIOTIM® UASB High volumetric loading rates can be reached in certain wastewaters. The BIOTIM® UASB (Upflow Anaerobic Sludge Blanket) reactor is the most commonly used system mainly because of its simplicity and robustness. BIOTIM® UAT The UAT (Upflow Anaerobic Tower) technology can be applied on easily and fast biodegradable wastewater flows generated by the Food & Beverage industry or the chemical industry. Applying hydraulic loading rates between 18-25 kg COD/m³ per day, the UAT solution generates a reduction of the reactor volume up to 33% compared to a conventional reactor. BIOTIM® UAC The BIOTIM® UAC (Upflow Anaerobic Contact) reactor is a hybrid reactor (combination of an UASB reactor with an AC process) for wastewater or concentrates that show no granule formation and/or require a longer hydraulic retention time than a UASB. BIOTIM® CSTR The BIOTIM® CSTR is Waterleau’s Continuous Stirred Tank Reactor. This type of reactor is typically used for very concentrated waters or for waters rich in solids. BIOTIM® Solids Waterleau’s BIOTIM® solids reactor is specially designed to treat sludge from municipal wastewater treatment plants. Sludge from both primary and secondary treatment is mixed and heated to accelerate biological conversion. BIOTIM® WET AD Waterleau has designed a BIOTIM® wet AD reactor with appropriate pre-treatment for the treatment of organic waste with a high moisture content such as kitchen and restaurant waste, manure or energy crop. BIOTIM® DRY AD The organic content of dry solids in mixed organic household waste is approximately 50% The BIOTIM® dry AD technology is specially designed to handle this type of waste successfully. SETTING STANDARDS IN DIGESTER TECHNOLOGY KITCHEN WASTE & MANURE 3-9 % DM 20-100 kg COD/m³ BIOTIM® UASB BIOTIM® UAT WATERLEAU UASB +/- 1% DM 3-6 % DM 3 ANAEROBIC DIGESTION OF EFFLUENTS FROM THE INDUSTRY The BIOTIM® and LUCAS® anaerobic wastewater treatment technologies are Waterleau’s flag-ship solutions for the production of biogas from bio-effluent. In combination with aerobic treatment, up to 99% from the effluent’s organic load can be removed, allowing the final effluent stream to be discharged safely or to be further treated for reuse purposes. Waterleau offers turn-key solutions for anaerobic digestion in different industries: Brewery industry Food & beverages Dairy industry Potato processing Sugar industry Bakery and yeast Agro-industry Chemical industry BEET/SUGAR CANE VINASSES CHEMICAL INDUSTRY Waterleau has designed and built an anaerobic treatment Waterleau’s daugther company KARY-PLANAQUA has plant for one of the largest producers of yeast and bakery designed and built the high rate anaerobic treatment plant at ingredients, capable of treating vinasses containing high levels Bitterfeld with a capacity of 40.000 kg COD/day. The Upflow of BOC, COD & TSS but also containing high concentrations of Anaerobic Tower (UAT) produces 1,2 MWe from high-loaded potassium, sulphates, nitrogen and bivalent ions. wastewater coming from the chemical industry. The anaerobic effluent is further treated in the municipal waste water The key to success of anaerobic treatment in this particular case treatment plant. is the spilt up between the biomass retention time and the hydraulic retention time: a BIOTIM® UAC reactor is followed by an external sludge separation system (SEPAFLOC®) with biomass recirculation. This solution combines the advantages of CSTR and UASB technology and excludes their potential drawbacks. Other advantages are the small footprint (up to 70% less space) and the lower anaerobic effluent TSS values, facilitating the aerobic post-treatment.

Next to sludge drying and incineration, Anaerobic Digestion is used for the degradation of the organic matter thereby reducing the sludge volume. The methane generation is a key advantage of the anaerobic process. The methane can be used in co-generators for producing heat and electricity.
