Abstract
Applying the concept that microbes utilize the organic substances in the influent, generate metabolic products, and reutilize these products in a typical activated sludge system, a double substrate model is proposed. In this model, system dynamic equations on biomass, primary substrate, and metabolic products are developed. These equations relate the microbial kinetics and pertinent process variables. The developed model simulates the time‐dependent respones of the effluent COD, residual primary substrate, and metabolic products in the effluent under step input loadings.Keywords
