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.

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.
