physical-chemical nitrogen removal wastewater treatment

Physical-Chemical Nitrogen Removal Wastewater Treatment

The relative costs of the physical-chemical nitrogen processes for a 10-mgd plant are • Ammonia stripping, 5 cents per 1,000 gallons • Selective ion exchange, 10-13 cents per 1,000 gallons • Breakpoint chlorination, 11 cents per 1,000 gallons These costs all are based on the removal of 25 mg/1 ammonia nitrogen.
