Abstract

A waste treatment process comprised of an ammonification system to convert soluble organic nitrogen into ammonia nitrogen, followed by a physico-chemical process to remove a substantial amount of the ammonia as a recovered ammonium sulfate fertilizer or ammonium hydroxide ('aqua ammonia'), and followed by an ammonia oxidation process to oxidize the remaining ammonia from the physico-chemical process. The process reduces ammonia and carbonaceous organic matter to less than 10 mg/l and recovers ammonia in the form of either ammonium sulfate or ammonium hydroxide.
