Physicochemical Removal of Nitrogen - Wastewater Treatment
Physicochemical Removal of Nitrogen - Wastewater Treatment

Breakpoint, chlorination, is a process that involves the addition of chlorine to wastewater to oxidize the ammonia in the wastewater to nitrogen gas and other possible stable compounds. It can, with proper control, theoretically remove all ammonia in wastewater and therefore it is used to polish the effluents from other nitrogen removal processes.
