Abstract

"MéTODO PARA LIMPEZA E DESINFECçãO SIMULTâNEA DE UM SISTEMA DE áGUA INDUSTRIAL". Métodos em linha e fora de linha para limpeza e desinfecção simultânea de um sistema de água industrial são descritos e reivindicados. Os métodos envolvem a adição à água do sistema de água industrial de um composto selecionado do grupo que consiste dos sais alcalinos de clorito e clorato e misturas dos mesmos; e um ácido, seguido por deixar a água no sistema de água industrial circular durante diversas horas. A reação dos sais alcalinos de clorito e clorato e ácido produz dióxido de cloro in-situ na água do sistema de água industrial. O dióxido de cloro mata microrganismos e o ácido atua para remover depósitos mediante as superfícies de contato de água do equipamento. Um método alternativo envolve o uso de um agente de quelação e um biocida. Outros reagentes possíveis de limpeza e desinfecção podem ser adicionados quando necessário que incluem inibidores de corrosão, agentes de quelação, biocidas, tensoativos e agentes redutores. Esses métodos de limpeza e desinfecção funcionam em uma variedade de sistemas de água industrial que incluem os sistemas de água de resfriamento e água de caldeira."METHOD FOR SIMULTANEOUS CLEANING AND DISINFECTION OF AN INDUSTRIAL WATER SYSTEM". Inline and offline methods for simultaneous cleaning and disinfection of an industrial water system are described and claimed. The methods involve adding to the water of the industrial water system a compound selected from the group consisting of chlorite and chlorate alkaline salts and mixtures thereof; and an acid, followed by letting the water in the industrial water system circulate for several hours. The reaction of alkali salts of chlorite and chlorate and acid produces chlorine dioxide in situ in the water of the industrial water system. Chlorine dioxide kills microorganisms and the acid acts to remove deposits through the water contact surfaces of the equipment. An alternative method involves the use of a chelating agent and a biocide. Other possible cleaning and disinfecting reagents may be added as needed which include corrosion inhibitors, chelating agents, biocides, surfactants and reducing agents. These cleaning and disinfecting methods work in a variety of industrial water systems including cooling water and boiler water systems.
