Abstract: “OXYGENATED CHLORINE FOR WATER TREATMENT AND ITS RESPECTIVE PROCESS OF OBTAINMENT AND APPLICATION”, more particularly it concerns a formulation of chemical compounds whose result is the obtainment of OXYGENATED CHLORINE; a highly effective compound capable of solving several problems of water treatment, mainly of swimming pools, in the process of disinfection, oxidation and combat to both organic and inorganic chloramines. The product considerably improves the process of water treatment because it reduces the time and quantity of chemical products used, as well potentiates the efficacy of sanitizing and oxidant properties of chlorine disinfectant “chlorine”, providing then advantages inherent to its applicability, making its characteristics innovative in the field.
