The mechanism of protein and amino acid removal from a digested night soil by an activated sludge was studied. The immediate removal amount of total albumin by activated sludge was 2.7 mg/Mixed Liquor Suspended Solid (MLSS)・g and that of albumin precipitated by trichloroacetic acid was 3.6 mg/MLSS・g. The removal rate of total albumin was 4.9 mg/MLSS・g/hr and that of the albumin precipitated was 6.1 mg/MLSS・g/hr. The protein precipitated and the total amino acids in the digested night soil decreased in the aeration tank by activated sludge but increased in the effluent from the night soil treatment plant. This phenomenon was explained by the autolysis of activated sludge in the sedimentation tank.
