Abstract

9989. Naylor, G. W., and Naylor, J. F. July 9. Aerating.-In a sewage purification tank of the kind in which air is forced through porous tiles provided over the whole surface of the floor, the air supply is so arranged that air is delivered through one portion of the surface at one time, and through the remaining portion when the supply to the first portion is cut off. Each of the two portions of the surface may comprise a set of alternate parallel strips or a set of segments or an inner or outer section or zone. Fig. 5 shows one construction in which each of the two portions of the surface comprises alternate rectangles c or d, one air supply being delivered through the rectangles d from longtitudinal pipes a, and the other air supply through the rectangles c from transverse pipes b. Each rectangle may be fitted with one or more tiles, a corresponding number of pipes a, b being provided. The operation'of the valves controlling the alternate air supplies may be effected by clock-work mechanism.
