Abstract:
PURPOSE: To provide a method for efficiently removing phosphorus without adding excess magnesium.
CONSTITUTION: Phosphorus in a waste water is removed as a solid particle of magnesium ammonium phosphate by adding a slurry of magnesium hydroxide into the waste water containing phosphate ion and ammonium ion so that the molar ration ((Mg2+)/(PO43--P)) of magnesium ion to phosphate ion is ≥0.001 to ≤0.1.
