Abstract

1420686 Settling tanks in series GYPSUM INDUSTRIES Ltd 13 Aug 1973 [14 Aug 1972] 38330/73 Heading B1D Sewage is aerated and delivered to a distribution chamber 5, then overflows into a first settlement tank 1, then underflows into a second tank 2 and then overflows into and out of a third tank 3 and any subsequent tanks. Settled sludge is withdrawn through bottom outlets 20 which are extended by swivellable variable level outlets (Fig. 3 not shown). The distribution chamber has a flow regulator 7, the tanks are rectangular in plan with part-cylindrical bottoms, and the bottoms may have pivoted manual or powered scrapers 23. A surface skimmer 11 with air lift pump 12 may be present in the first tank. The third tank may have a baffle 15 and overflow launders 17 which lead to discharge channels (18) (Fig. 2 not shown). Sets of settlement tanks may operate in parallel. Chlorine may be added through pipe 16.
