Abstract
1511047 Sewage treatment ACTIVOX Inc 7 July 1975 28535/75 Heading C1C A continuous activated sludge sewage treatment process comprising, in continuous manner, injecting raw sewage liquid into a reservoir providing a single horizontal closed loop path, circulating the liquid around said path at speed of at least 8 feet per second, aerating the liquid in said path to promote aerobic decomposition of the sewage and formation of nitrate compounds in said liquid, circulating the aerated liquid around said path for a first distance in which said decomposition proceeds until the liquid is substantially devoid of oxygen at the point of raw sewage injection, circulating the liquid containing nitrate compounds and raw sewage around said path for a second distance in which denitrification proceeds in said liquid until it reaches the next point of aeration in said path, continuously removing treated liquid, for clarification and settling of sludge therein, at a rate approximating the rate of injection of the raw sewage liquid, discharging the resulting clarified liquid effluent and returning at least a portion of the settled sludge to the liquid in said reservoir, said second distance being at least 10% of the sum of said first and second distances.
