Sewage Sludge Treatment

Sustainable sewage and waste concept for urban regions in China – semi-centralised supply and disposal systems

The project participants develop a sustainable concept for supply and disposal in urban regions. Greywater is collected separately and treated and the effluent sludges from blackwater treatment are used for power generation. Fermentation of biological waste produces lactic acid, thus reducing the waste destined for landfill.
