Abstract
1409088 Aerobic sewage treatment AMES CROSTA Ltd 27 Feb 1974 [19 Dec 1972] 58656/72 Heading C1C [Also in Division B1] An aerating plant for sewage or waste water comprises a ring of tanks 13 each of which has a rotatable surface aerator 14, and a central distribution chamber 10. There are controllable gates 21 between the chamber 10 and tanks 13 and controllable gates 24 in the walls 12 between the tanks, each of which has an adjustable overflow outlet in the form of a weir 26. As shown there are four tanks 13 but there may be a greater number, having a circular or polygonal perimeter wall and a polygonal distribution chamber. The plant may perform the activated sludge process in several ways (see Figs 3-7, not shown): the influents and recycled sludge may be mixed in the chamber 10 and supplied separately to each tank 13 (Fig. 3); or be passed through them all in succession (Fig. 4); or fed in different amounts to all except the last (Fig. 5); sludge may be pre-aerated in the first tank (Fig. 6), or in all except the last (Fig. 7).
