Abstract

A laboratory study was conducted to determine the effect of bacterial augmentation with LLMO (liquid live microorganisms) on the activated sludge treatment of potato wastewaters. Completed mixed activated sludge bench scale reactors were used in this study. Parameters varied during the continuous reactor run included hydraulic detention time, LLMO addition, and powdered activated carbon addition. The hydraulic detention time lasted 1, 2, and 3 days, while the sludge age was maintained at 10 days for both reactors. The bio‐augmented reactor had a better COD removal than the non‐bio‐augmented reactor at a lower MLVSS level in the reactor. It is concluded that bacterial augmentation with LLMO improved slightly the COD removal efficiency in treating potato wastewaters with the activated sludge process. The bio‐augmentation increased the substrate removal rate, increased the oxygen utilization, and decreased the excess sludge production. Copyright © 1988 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim
