Abstract

This study was conducted to improve struvite precipitation for NH₄-N removal purpose in landfill leachate. For this purpose, we evaluated the effect of the feeding sequence of precipitating reagents (magnesium, orthophosphate, and buffering reagent) on NH₄-N removal by forming struvite deposits. Struvite precipitation effectively proceeded by an addition of excess magnesium and phosphate sources followed by an addition of the buffering reagent, in which condition the local formation of inappropriate deposits or the contamination of the desired struvite was minimized. We also tested the effect of struvite addition as the seeding materials on NH₄-N removal. Seed addition would increase the potential for the struvite crystal growth, which enhanced NH₄-N removal performance in landfill leachate treatment.
