摘要： An internally fed drum filter for treating waste water, includes an inlet distribution arrangement for distributing waste water entering the drum filter via an inlet duct, characterized in that the inlet distribution arrangement includes an adjustable flow deflection member arranged near the outflow opening of the inlet duct, downstream thereof, for adjusting the flow characteristics of waste water entering the drum filter via the inlet duct.

摘要： 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.
