Abstract: 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.

Abstract: 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.

Abstract: The invention relates to a separator device for separating a first liquid substance from a second substance, the two substances forming a mixture. The apparatus comprises a vessel with an inlet for receiving the mixture, a first outlet for discharge of a first fraction of the mixture, a second outlet for discharge of a second fraction of the mixture and a flow element. The flow element comprises a number of parallel tubular channels defining a flow path for the mixture, the channels having an gilet end for receiving the mixture and an outlet end for discharge of the first fraction, a length direction of the channels being inclined with respect to a horizontal direction, wherein in a transverse cross section through the flow element, the channels form a two-dimensional array of closed cells, each cell defining a boundary of a flow channel, the cells being arranged in at least two rows, each cell in a first row contacting with its perimeter a cell in the second row.
