The technology of magnesium ammonium phosphate(MAP) is one of effective removal of high strength ammonia nitrogen and phosphate in wastewater.

The precipitation process via Magnesium Ammonium Phosphate(MAP) could remove and recycle the high strength phosphorus existing in sludge liquor and so decrease the loading rate of phosphorus when the sludge liquor is recycled to the front process.

By preliminary economic analysis,the method of aeration and crystallization formed magnesium ammonium phosphate(MAP)seems more economical and applicable.
