System for optimized control of multiple oxidizer feedstreams

A system for advanced oxidation technological control of an electrolyte containing fluid in a multiple oxidizer environment comprising:

• at least one amperometric sensor means;
• at least one amperometric sensor means isolated from said electrolyte containing fluid by a gas permeable membrane;
• and
• a means for process control in communication with each of said sensor means;
• wherein production and/or introduction of hydroxyl free radicals is controlled in said multiple oxidizer environment.

In 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 including the steps of:

• 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 750 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;
• adding a peroxygen compound at a rate and in an amount sufficient to realize a level effective 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;
• the improvement comprising
• providing at least one amperometric sensor means;
• and
• providing a means for process control in communication with each of said sensor means;
• whereby said means for process control is adapted to adjust the level of each of said halogen donor and peroxygen compound.

• the improvement comprising;
• providing at least one amperometric sensor means;
• and
• providing a means for process control in communication with each of said sensor means;
• whereby said means for process control is adapted to adjust the level of each of said halogen donor and peroxygen compound.
