Waste water treatment apparatus

摘要

A treating apparatus is shown for removing cloggants from the pores and surfaces of aeration diffuser elements used in an activated sludge treatment process or the like. The apparatus pumps a liquid acid solution through the aeration piping network of the system and out through the diffusers for reacting the acid with the cloggants in the pores of the diffusers. After the cleaning action has been completed, the apparatus produces an agitation throughout the diffuser system being cleansed as the liquid acid is being pumped out of the system and the air flow is being reestablished.
