Abstract

UN METODO PARA TRATAR AGUA DE ALIMENTACION CON UNA MEMBRANA DE OSMOSIS INVERSA (OI) Y REDUCIR LA TENDENCIA DE LA MEMBRANA DE OI A ENSUCIARSE DEBIDO AL ALUMINIO EN EL AGUA DE ALIMENTACION O AGREGADO COMO PARTE DE UN PRE-TRATAMIENTO, QUE COMPRENDE: MEZCLAR UN COAGULANTE DE SAL DE ALUMINIO CON EL AGUA DE ALIMENTACION PARA FORMAR EL AGUA DE ALIMENTACION Y PRECIPITAR LOS PRECIPITANTES A BASE DE HIDROXIDO DE ALUMINIO DEL AGUA DE ALIMENTACION; DIRIGIR EL AGUA DE ALIMENTACION A UNA UNIDAD DE SEPARACION POR MEMBRANA DE MICROFILTRACION O ULTRAFILTRACION Y PRODUCIR UNA CORRIENTE DE PERMEADO Y UNA CORRIENTE DE RECHAZO DONDE LA CORRIENTE DE RECHAZO INCLUYE LOS PRECIPITANTES A BASE DE HIDROXIDO DE ALUMINIO; DIRIGIR LA CORRIENTE DE PERMEADO A LA MEMBRANA DE OI Y FILTRAR LA CORRIENTE DE PERMEADO PARA PRODUCIR UNA CORRIENTE DE PERMEADO Y UNA CORRIENTE DE RECHAZO; Y CONTROLAR LA CONCENTRACION DE ALUMINIO EN EL PERMEADO HACIA LA MEMBRANA DE OI CONTROLANDO EL TIEMPO DE RESIDENCIA HIDRAULICO DEL AGUA DE ALIMENTACION COAGULADA PARA EVITAR LA RESOLUBILIZACION DEL ALUMINIO.
