Abstract

Ammonia removal from water was studied through hydrophobic hollow fiber and flat sheet membrane contactors. These hydrophobic membrane contactors were used to separate the water stream to be treated and a receiving solution. A diluted solution of sulfuric acid was used as a receiving solution to accelerate the removal of ammonia by means of a reaction converting the ammonia into ammonium sulfate ((NH4)(2)SO4), which could be recovered as a by-product [1-3].
