The reaction of wastewater with biologically active sludge to remove degradable pollutants from the wastewater is a widely applied treatment technique. The microscopic organisms in the sludge metabolize the degradable constituents of the waste, utilizing the products for growth and releasing less noxious byproducts into the treated water. The activate sludge treatment process consists of two basic unit operations: (1) aeration, and (2) clarification. The efficiency of this process depends upon the satisfactory functioning of both the biological oxidation and the solids separation processes. This report concentrates on two problems that inhibit satisfactory separation of sludge solids: (1) bulking, and (2) foaming. The report also discusses their causes and presents means by which they may be controlled.
