METHOD AND SYSTEM FOR ANAEROBIC TREATMENT OF ORGANICALLY LOADED WASTEWATER

METHOD AND SYSTEM FOR ANAEROBIC TREATMENT OF ORGANICALLY LOADED WASTEWATER

In a method of anaerobic treatment of an organic waste stream (1), a stream originating from an anaerobic reactor (5) is fed to a first separating unit (33) to be separated into a sludge fraction (7″) containing between 50% and 80% of the solids by weight and a second fraction (7). The second fracti...

Zusammenfassung:In a method of anaerobic treatment of an organic waste stream (1), a stream originating from an anaerobic reactor (5) is fed to a first separating unit (33) to be separated into a sludge fraction (7″) containing between 50% and 80% of the solids by weight and a second fraction (7). The second fraction (7) is fed from the first separating unit (33) into a Dissolved Gas Floatation (DGF) unit (16). The sludge fractions (7″) and (9) from the separator units (33) and (16) are fed back to an inlet 41 of the reactor 5.
