Abstract

<PICT:1073383/C1/1> Raw sewage is supplied via crude mechanical sorting 3 and grease trap 8 to clarifier 9. The liquid passes via line 13 through biological filter 14 to a secondary clarifier 16 for discharge of purified liquid effluent at 18. Sludge from clarifier 9 is concentrated (12) digested (21) and centrifuged (27) to give a solid product at 35 and a liquid product which after treatment on beds 40, and optionally chemical treatment, is returned via line 41 to the start of the process with overflow in concentrator 12. Sludge from clarifier 16 is recycled via line 17.
