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.
L'invention concerne un procédé d'optimisation du taux d'oxydation au moyen d'une combinaison d'halogène, p. ex. des donneurs de chlore, et de peroxygène, p. ex. du monopersulfate de potassium. Le composé peroxygène élève le potentiel d'oxydoréduction de la masse d'eau traitée. Simultanément, un donneur d'halogène est ajouté à la masse d'eau pour maintenir un niveau ppm d'halogène libre suffisant pour assurer le nettoyage. La quantité d'halogène libre est réduite et la plage efficace de potentiel d'oxydoréduction augmentée à 700 mV-850 mV par addition d'une quantité efficace d'un agent de coagulation. Les taux d'alimentation et les concentrations des deux oxydants sont optimisés, de façon à obtenir et maintenir les paramètres fixés. Un niveau important d'oxydation est maintenue, éliminant les produits dérivés de l'eau et de l'air environnant.
