Abstract

<p> Bench&hyphen;scale laboratory studies were conducted to examine the bacterial populations in the activated sludge process under different operating conditions and to determine the effects of bioaugmentation with liquid mixed culture bacteria on the bacterial populations and the process efficiency. Results indicate that bacterial populations were not related to the mixed liquor volatile suspended solids (MLVSS) concentrations. The organic removal rates were related to the logarithm of the bacterial concentrations in the mixed liquor. A very reliable kinetic model for organic removal was developed based on heterotrophic bacterial concentrations. Bioaugmentation improved organic removal rate coefficients, but resulted in higher organic residual in the effluent. Copyright © 1990 WILEY&hyphen;VCH Verlag GmbH & Co. KGaA, Weinheim</p>
