Abstract

PROCEDIMIENTO E INSTALACION PARA PROTEGER LAS CANALIZACIONES DE AGUA CONTRA LA CORROSION; EN ESTE PROCEDIMIENTO SE AÑADE AL AGUA TRANSPORTADA LA CANTIDAD DE CAL APROPIADA PARA CONFERIRLE PROPIEDADES INCRUSTANTES. ANTES DE SER INTRODUCIDA EN EL SATURADOR (S), EL AGUA TOMADA DE LA CANALIZACION SE MEZCLA EN UN DESCARBONATADOR (D) CON UNA SOLUCION DESPROVISTA DE CO2 TOTAL Y CARGADA DE CAL PROVENIENTE DEL SATURADOR (S), A FIN DE PERMITIR LA ELIMINACION CASI COMPLETA DEL CO2 TOTAL EN EL DESCARBONATADOR (D) POR PRECIPITACION DE CACO3. UTILIZACION ESPECIAL PARA PROTEGER CONTRA LA CORROSION LAS PAREDES INTERIORES DE METALES FERREOS O A BASE DE CEMENTO DE LAS CANALIZACIONES DE AGUA.
