Title: Ammonia capture and recovery system and method for removing ammonia from a wastewater stream

Abstract

A wastewater stream including ammonia and water is fed to at least one packed column including packing material having a surface of solid magnesium phosphate or solid magnesium ammonium phosphate or both. Each of the packed columns is capable of cycling between an ammonia absorption operation and an ammonia regeneration operation. The magnesium phosphate compound reacts with the water and ammonia to form a magnesium ammonium phosphate compound. In one embodiment, this system provides for the regeneration of the magnesium ammonium phosphate compound for further use as an ammonia sorber. In another embodiment, the magnesium ammonium phosphate compound is used as fertilizer. Additionally, the ammonia capture and recovery system may be used in conjunction with other unit operations in an overall wastewater treatment system.
