Removal of Ammonium (NH4) and Organic Matter (COD) In Landfill Leachate Under Anaerobic and Aerobic Algae Culture In Continuous Systems

Abstract

Final Disposal (Landfill) generally produce pollutants such as leachate and can have a negative impact on the environment. In general, landfill leachate containing high of organic matter and high of nitrogen, as well as Ngronggo landfill leachate in Salatiga, far exceeded the applicable waste water. To reduce the organic matter and ammonium contens, Ngronggo landfill leachate was processed under anaerobic-aerobic process (algae-culture) in continuous system, with residence time of 24-hour for one week. The results showed that anaerobic-aerobic (algae culture) in continuous system were conducted in a laboratory scale give a significant results to removing over 90% of COD and ammonium, and produce water quality that meets with the quality standards of waste water.
