Treatment plant for fermentation residues from a Biogas Plant
NES Natural Engineering Solutions GmbH
The Biogas Plant Geotexia in France obtains 80,700 m³ of fermentation residues per year. The fermentation residues are treated according to the MPS-method (Multi-Phase-Separation) developed by the A3 Water Solution GmbH. Additionally to the solid/liquid separation, the ultrafiltration and reverse osmosis stages process includes further reverse osmosis units to increase the concentration of the preceding stages.

GWE Biogas Ltd., UK
During the fermentation of organic waste, for instance food residues and food with expired shelf-life, about 67,000 m³ of fermentation residues are obtained in the Biogas Plant Sandhill, Great Britain, per year. These fermentation residues are prepared in the fermentation residue treatment plant using the MPS method (Multi-Phase-Separation) developed by the A3 Water Solutions GmbH in a way that they can be led to a discharge system. Additionally to the solid/liquid separation, the ultrafiltration unit and the reverse osmosis stage, a further reverse osmosis stage has been installed to increase the concentration of the preceding stage and with this, to reduce the obtained mass quantity.

Expansion of an existing membrane plant treating fermentation residue from a biogas plant in Inwil / Switzerland
The biogas plant owned by Swiss Farmer Power AG in Inwil / Switzerland is already equipped with an A3 Water Solutions GmbH effluent treating membrane plant. In order to increase the reverse osmosis (RO) effluent concentration, an additional RO stage was installed. Download PDF (132 KB)

Replacement of an existing membrane plant treating effluent from a biogas plant in Thallwitz
Ökotec Anlagenbau GmbH operates a biogas plant to utilize organic waste. The installed effluent treatment technology has not been reliable and has experienced severe glitches in past years. A3 Water Solutions GmbH received the order to replace the existing submerged ultrafiltration hollow fiber membrane modules with A3’s proven membrane technology.
|Treatment plant for process water|
Supply of a treatment plant for process water (fermentation residue) generated by the biogas plant in Inwil
CTU Conzepte Technik Umwelt AG builds a biogas plant for Swiss Farmer Power AG in Inwil, Switzerland. The plant’s input consists mostly of liquid manure and organic waste from agriculture. Since the process water from the fermentation process contains high concentrations of solids, ammonium, additional nutrients and salts, an on-site treatment process is require before the water can be discharged to the public sewer system. A3 Water Solutions GmbH provides a process water treatment plant for fermentation residue including solid/liquid separation and membrane stages. Download PDF (132 KB)

Construction of a clean water production plant for the ’Klarsee’ Bioenergy Park in Penkun
NAWARO Engineering GmbH, a project company of BioEnergie AG located in Leipzig, is erecting the „Klarsee“ Bioenergy Park in Penkun. All of the 40 individual digesters of the Bioenergy Park are scheduled to go onstream by fall 2007. This will make the installation the currently biggest biogas power plant worldwide having a total electric power output of 20 megawatts. The arising digestion products (approx. 408,000 t/a) are pelletized in an associated fertilizer plant to produce depot fertilizers. The liquid discharged from the fertilizer production process is treated in a vacuum evaporation unit where separation into a water and a concentrate stream takes place. The condensate arising from the evaporation process (approx. 280,000 t/a) contains large amounts of ammonium nitrogen, hardness-forming substances as well as other nutrient salts and is therefore treated in an A3 reverse osmosis plant to obtain clean water which is again fed to the biodigesters or to some extent disposed of via the discharge system.
