Ammonia-nitrogen and phosphate removal in leachate using algae and bacteria mixture
Leachate is a liquid that has been produced by the waste especially organic waste. In an engineered sanitary landfill, biological treatment is a common practice to reduce the leachate contaminants. The effluent from treated leachate needs to comply with the standard set by the Department of Environm...

Leachate is a liquid that has been produced by the waste especially organic waste. In an engineered sanitary landfill, biological treatment is a common practice to reduce the leachate contaminants. The effluent from treated leachate needs to comply with the standard set by the Department of Environment (DOE), Malaysia before it is being released into the river. The leachate contains a high number of contaminants such as ammonia-nitrogen, phosphorus, heavy metal, biochemical oxygen demand (BOD), chemical oxygen demand (COD) and suspended solids. This study focused on the possibility of treating leachate by using algae and bacteria in biological treatment in removing ammonia-nitrogen and phosphate in leachate obtained from Air Hitam Sanitary Landfill, Puchong.
