Abstract

824,376. Aerating sewage. DISTILLERS CO. Ltd., and ACTIVATED SLUDGE Ltd. Nov. 8, 1957 [Dec. 19, 1956], No. 38638 /56. Class 111. [Also in Group VI] A disperser for dispersing oxygencontaining gases through liquid sewage comprises a gas supply pipe 1, one or more members 4 connected thereto and on each member a diaphragm 10 of flexible elastic material, e.g. rubber, having perforations 7 formed by puncturing means without removal of material, the diaphragm having a flange formed by downwardly or downwardly and inwardly turning the periphery of the diaphragm, the flange fitting over or around and beneath the rim of the member. In Fig. 1, air passes along the pipe 1 (shown in cross-section) through orifice 2 in bolt 3 and into the chamber formed between the member 4 and a rigid diaphragm supporting sheet 5. From this air passes through a central hole 6 in sheet 5 and escapes through perforations 7 in the diaphragm into the liquid sewage in which the device is immersed. The rigid supporting sheet supports the diaphragm against external liquid pressure when air flow ceases, thus preventing inward distension of the diaphragm with resulting passage of liquid through the perforations into the supply pipe. In Fig. 3, the member 4 is so shaped that its upper surface supports the diaphragm when air flow ceases. In Fig. 8, the downwardly turned periphery of the diaphragm forms a flange 17 which is held against rim 16 of the member 4 by means of a clip 18. The diaphragm may be square, oblong, or oval in shape but is preferably circular ; it can be provided with a thickened periphery, as in Figs. 1 and 3, to increase its grip around the rim of the member 4. Specification 605,046 and 660,666 are referred to.
