Abstract

In this study, activated biochar from municipal sewage sludge was used for the treatment of sewage wastewater. The sewage physicochemical parameters were measured before and after bio filtration with biochar applying the principle of adsorption using the standard methods. Bio char with 500 m2/g surface area and particle size of 0.5-1.0 mm was used at a loading rate of 2.5 g/L and treatment time of 40 hours. The changes in the sewage physicochemical parameters which included biological oxygen demand (BOD), chemical oxygen demand (COD), total phosphates (TP), total solids (TS) and total Kjeldahl nitrogen (TKN) and were measured using standard methods. Upon subjecting the sewage water to the bio char, a reduction of 94%, 90%, 80%, 83% and 82% were observed for the BOD, COD, TP, TS and TKN respectively. The sewage pH also changed from alkaline to neutral. The observed results indicated that sewage sludge bio char can effectively treat sewage wastewater.
