Abstract

In biological effluent treatment by the activated sludge process, the concentration of the degradable impurities in the effluent fed is maintained so high that the formation of bulking sludge is promoted. This is effected by adjusting the space loading to a value from 1 to 2. Due to the degradation properties of the microorganisms forming the bulking sludge, more organic pollution load in the effluent can be degraded. Subsequently, the activated sludge is separated from the treated effluent and at least partially recirculated.
