Abstract

"SISTEMA E MéTODO PARA TRATAMENTO DE áGUA". Trata-se de um sistema de tratamento que proporciona água tratada ou amolecida a um ponto de uso por meio da remoção de pelo menos uma parte de qualquer espécie indesejável contida na água de uma fonte de água. O sistema de tratamento pode ser operado para reduzir a probabilidade de formação de qualquer crosta que possa ser gerada durante a operação normal de um dispositivo eletroquímico. A formação de crosta no sistema de tratamento, incluindo seus componentes molhados, pode ser inibida revertendo-se ou substituindo-se o líquido que tem espécies que causam dureza com um outro líquido tendo uma baixa tendência a produzir crosta, tal como uma água com baixo LSL. Diversos arranjos de componentes no sistema de tratamento podem ser lavados direcionando-se as válvulas e as bombas do sistema para deslocar o líquido que tem espécies que causam dureza com um líquido que tem pouca ou nenhuma tendência a formar crosta.
