Abstract
A method of treating a landfill leachate containing ammoniacal nitrogen and phosphate by mixing with seawater to precipitate magnesium ammonium phosphate (MAP) also known as struvite. Effects of pH, temperature, stirring speed, and magnesium to ammonia molar ratio on leachate properties such as COD, ammoniacal nitrogen, phosphate content, color, turbidity, amount of magnesium, iron and zinc are disclosed. The method provides high removal efficiency for removal of ammoniacal nitrogen, phosphate, COD, color and turbidity. The method provides a cost-effective system for treatment of landfill leachate and recovery of MAP.
