Preliminary studies of advanced wastewater treatment for brewing effuluent were conducted using small scale pilot plants and actual effuluent discharged from activated sludge treatment facilities of a brewery. The pilot plant had a capacity of 50l/min and was composed of a rapid mixing tank, gentle stirring path and a horizontal sedimentation tank. Poly aluminum chloride was used as the flocculant. The floc observed was light and weak which was the same as that observed in the case with a dilute solution, so that the floc tended to break up in the gentle stirring path and to re-flocculate at the inlet zone of the sedimentation tank. Up to the outlet of the sedimentation tank, 473 COD, 97% turbidity, 90% colour in the effuluent were removed.
