Anaerobic Digestion Steady State model parameter estimation for determination of waste activated sludge characteristics by Du Toit, Johan

“…It was determined that the novel approach by Maake & Ikumi, (2021) was very reliable in determining Chemical Oxygen Demand (COD) removal, Free and Saline Ammonia (FSA), system effluent pH and total alkalinity. With respect to the Ortho-Phosphates (OP), the parent system from where the WAS is sourced, had a long SRT. …”
