Description:
Pilot plant aerated lagoon and laboratory completely mixed activated sludge treatment studies of corn wet milling wastes showed that either process could produce a satisfactory effluent. A full scale completely mixed activated sludge treatment plant was designed from laboratory reactor data. Soluble BOD removal performance has been about as predicted from the laboratory data. Although total BOD removal often exceeds 90%, the nature of the waste is such that the effluent BOD and suspended solids concentrations usually do not meet effluent criteria. The effluent suspended solids consist almost entirely of bacteria. The BOD is almost entirely due to the oxygen demand of these bacteria.
