Abstract

Leachate from sanitary landfills is a strong wastewater in terms of organic matter and ammonia. Organic matter can be reduced by anaerobic plus aerobic treatment; however, ammonia reduction by nitrification often poses problems due to inhibition. In this study, ammonia removal by physical chemical treatment from young leachate and anaerobically treated young landfill leachate was experimentally investigated. Magnesium ammonium phosphate precipitation (MAP) and ammonia stripping at pH 12 provided ammonia removals over 90 and 85% respectively. Up to 80% COD removal was obtained with MAP precipitation of raw leachate.
