Abstract

A waste water system having an anaerobic reaction reservoir (1), a separator (4) separated by a generally vertical dividing wall (13), an influent inlet (6) through which waste water enters the anaerobic reaction cell (1), mixing means (9a), and an optional conduit (23) for removing mixed liquor. The disclosed system is capable of concentrating activated denitrified sludge, and recycling the denitrified sludge to an aerobic cell, provides a highly efficient method and apparatus for sewage disposal. The basic system is described in several embodiments which are selected on the basis of the waste water content. The improved system minimizes dilution of mixed liquor, increases hydraulic retention time at the various process points, and conserves energy.
