Wastewater Characterization for Evaluation of
Biological Phosphorus Removal

Summary

A simple COD fractionation method was developed to characterize the wastewater specifically aimed at biological phosphorus removal design. Simple methods were also proposed to determine Y, k_d, _max, and K_s. These kinetic parameters and the detailed fractionation results of raw wastewater COD, nitrogen, and phosphorus can be used in biological nutrient removal process design computer programs to obtain optimum design information for wastewater treatment plants. The models are useful in determining the process volume and evaluating the effect of COD loading, biomass concentration, and sludge age on the phosphorus and nitrogen removal efficiencies. The methods provided for parameter determination will allow smaller wastewater treatment plants or industries to evaluate the feasibility of biological phosphorus removal of their wastewater with minimum cost.
