Settling properties of activated sludge typically establish the performance and the cost of biological wastewater treatment plants, and they are considerably affected by the solids concentration of the sludge and the mean cell residence time of the system. In this work, effects of mean cell residence time of the system and solids concentration of sludge on the settling properties of activated sludge were studied. By statistical analysis of the laboratory data, mathematical expressions were suggested to express the relationships that existed between the above parameters.
