A process for optimizing the rate of oxidation using halogen, e.g. chlorine donors to prevent the accumulation of undesirable chlorinated by-products. The feed rate of a chlorine donor is controlled for maintaining a desired ORP. The amount of free halogen is reduced and the ORP range expanded by addition of an effective amount of a coagulating agent. The rate of oxidation is sufficient to prevent the accumulation of the undesirable by-products. Treatment removes the by-products from the water and surrounding air by maintaining continuous breakpoint halogenation conditions.

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

1. 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 said body of water's ORP; comparing the monitored ORP to a set-point value calculated to be within an effective range 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 a monitored ORP within said range wherein said halogen donor source is selected from the group consisting of calcium hypochlorite, sodium hypochlorite, lithium hypochlorite, and mixtures thereof; regulating the rate of addition of said halogen donor source to maintain the ORP within said effective range; feeding a coagulating agent in an amount effective to reduce the amount of halogen donor required to maintain the ORP within said effective range; reabsorbing said volatile halogen compounds within said body of water; and oxidizing the reabsorbed compounds.
