Abstract
Wastewater treatment methods and systems for removal of phosphorus (P) and nitrogen (N) from wastewater and for recovery of them as usable materials. Sufficient amount of dolomite lime and slaked dolomite lime is added into the wastewater to increase the pH of the wastewater to above 8.5 and to form P precipitates and to convert ammonium to ammonia in a precipitation-ammonia stripping reactor or a continuous flow precipitation reactor. The P precipitates are separated from the wastewater and recovered as usable solid material. The ammonia gas is absorbed and concentrated with acid solution in an ammonia absorption tower as usable liquid material.
