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 prop erties 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.
