OPTIMIZATION OF ACTIVATED SLUDGE REACTOR CONFIGURATION: KINETIC CONSIDERATIONS

摘要

To evaluate and design staged activated sludge systems it is necessary to determine the biomass requirement for a given configuration. This depends on both kinetics and treatment requirements. We present a procedure to determine the optimum reactor configuration for a range of influent and effluent substrate concentrations, half saturation coefficients, and number of tanks in series for both inhibitory and non-inhibitory substrates. Dimensionless plots of the results show the minimum biomass requirement of the series relative to that for a single CSTR and the optimal relative sizes of the tanks.
