In order to decrease excess sludge production, the treatment of synthetic sewage was carried out under conditions of balancing microbial growth and cell decay with a high concentration of activated sludge supplemented with a ferromagnetic powder (magnetic sludge). The leakage of magnetic sludge was prevented by the combined treatment of magnetic separation and gravitational sedimentation. COD_<Cr> removal and effluent suspended solids concentrations were maintained at 85-94% and 5-24mgl^<-1>, respectively, over 30 d. Meanwhile, mixed-liquor volatile suspended solids concentration in the aeration tank remained virtually constant and excess sludge was not produced.
