Abstract
1,235,948. Sewage treatment. ECODYNE CORP. 27 March, 1969 [29 March, 1968], No. 16099/69. Heading C1C. A sewage treatment plant comprises a tank 10 which includes a clarifier section 47 and an aeration section 30 in which an aerator 50 causes solid-bearing liquid sewage to follow a rotational flow path, inlet ports 55 in a partition 31 through which a portion of the rotating sewage flows into the clarifier section, means (e.g. a channel 65 formed by the partition and a secondary baffle 60) to direct the flow of the portion of rotating sewage downwardly in the clarifier section, and an outlet 46 through which solids descending in the clarifier section flow back into the aeration section. The tank 10 may be of sheet steel and receive the sewage through a pipe 23. The sewage passing into the clarifier section 47 is throttled by the inlet ports 55 and the secondary baffle 60 so that it flows from the channel 65 and down the partition 31 in laminar fashion. Floatable solids which rise to the surface in the clarifier section 47 and an inlet chamber 68 of the clarifier section are returned by the rotational flow of the sewage to the aeration section 30 through an assembly 80 which comprises a trough (81), Fig. 2 (not shown), which extends from the clarifier section to the aeration section. The trough (81) has an inlet (83) in the clarifier section 47, lateral inlets (85) in the inlet chamber 68, convergent inner side walls (86), and a wedgeshaped plate (90) adjacent an outlet (82) in the aeration section 30. Clarified effluent leaves the tank 10 via a weir 75. In a modification, Fig. 3 (not shown), the tank may have two aeration sections (130), (130a), each separated from a central clarifier section (147) by partitions (131), (131a).
