Abstract

MéTODO APERFEIçOADO DE TRATAR áGUA. A presente invenção e um método de tratar um sistema de água parada que compreende a administração ao sistema de água parada de uma mistura que compreende hipoclorito de cálcio e sais borato. O método de tratar um sistema de água parada proporciona cloro livre para o sistema de modo mais eficaz do que os métodos da técnica anterior, estabiliza o pH do sistema de água parada e reduz os efeitos colaterais indesejados da adição de hipoclorito de cálcio sozinho.IMPROVED METHOD OF TREATING WATER. The present invention is a method of treating a standing water system which comprises administering to the standing water system a mixture comprising calcium hypochlorite and borate salts. The method of treating a standing water system provides free chlorine to the system more effectively than the prior art methods, stabilizes the pH of the standing water system and reduces the unwanted side effects of adding calcium hypochlorite alone.
