Title:
AIR AND WATER PURIFICATION USING CONTINUOUS BREAKPOINT HALOGENATION AND PEROXYGENATION
Document Type and Number:
WIPO Patent Application WO2002035908
Kind Code:
A3
Abstract:
A process for optimizing the rate of oxidation in aquatic facilities using a combination of halogen, e.g. chlorine donors and peroxygen, e.g. potassium monopersulfate. The peroxygen compound elevates the oxidation-reduction potential of the body of water being treated. Simultaneously, a halogen donor is added to the body of water to maintain a ppm level of free halogen sufficient to insure sanitization. The amount of free halogen is reduced and the ORP effective range expanded to 700 mV-850 mV by addition of an effective amount of a coagulating agent. The feed rates and concentrations of both oxidizers are optimized so as to achieve and maintain the targeted parameters. A high level of oxidation is maintained which removes by-products from the water and surrounding air.
