Abstract:
A process for removing volatile halogenated compounds including chloramines and/or bromamines from the air and treating a body of water in an indoor aquatic facility comprising:disposing an oxidation-reduction potential (ORP) sensor in fluid communication with a body of water within said facility; continuously monitoring the ORP of said body of water; comparing the monitored ORP to a set-point value calculated to be within a range effective to permit oxidation of said volatile halogenated compounds wherein the effective range of ORP is from 700 mv-850 mv; adding a halogen donor source in an amount and at a rate sufficient to realize an optimum free halogen level sufficient to sanitize said body of water; feeding a coagulating agent in an amount effective to reduce the amount of halogen donor required to maintain the ORP within said effective range; adding a peroxygen compound at a rate and in an amount sufficient to maintain the ORP within said effective range; optimizing the ratio of halogen donor source to peroxygen compound to sustain the optimum free halogen level while maintaining the effective ORP value; maintaining a sustained high rate of oxidation in said body of water sufficient to cause the volatile halogenated compounds in the air to be reabsorbed therein; and oxidizing the reabsorbed compounds.
