Abstract

Copper One of the techniques used for the stabilization of sewage sludge is anaerobic digestion. The effluent from anaerobic digesters usually requires further treatment since they contain high concentrations of N and P as a result of volatile solids destruction. In this study, a control was developed over the nutrient ions within the anaerobic digester by using substrate with high concentration of Mg²⁺ ion. The amount of Mg²⁺ ion added was determined based on the release rate of N and composition of magnesium ammonium phosphate. The results showed 50% removal of NH₄⁺ and PO₄^3- can be achieved without compromising the performance of the reactor in COD and ySS removal and biogas formation.
