Abstract

ESTA INVENCION ESTA DENTRO DEL AMBITO DE LAS INSTALACIONES DE FILTRACION Y DE DEPURACION DE LIQUIDOS, ESPECIALMENTE LAS AGUAS, DEL TIPO QUE COMPRENDE UN BUCLE DE CIRCULACION DE LAS AGUAS QUE HAY QUE TRATAR INCLUYENDO AL MENOS UNA MEMBRANA DE FILTRACION TANGENCIAL. LA INVENCION TIENE POR OBJETO PROVEER UNA NUEVA INSTALACION DE FILTRACION DE MEMBRANA TANGENCIAL CON INYECCION DE OZONO, QUE PERMITE LIMITAR LA COLMATACION DE SUPERFICIE, INTERNO Y QUIMICO DE LA MEMBRANA. SEGUN LA INVENCION, LA INSTALACION COMPRENDE UNOS MEDIOS (2) DE ADICION DE UN GAS OXIDANTE AL LIQUIDO QUE HAY QUE TRATAR, EN EL BUCLE MAS ARRIBA DE LA MEMBRANA DE MANERA A FORMAR UNAS MICROPOMPAS DE DICHO GAS DE UN TAMAÑO TAL QUE CREEN UNAS TURBULENCIAS EN EL LIQUIDO AL DERECHO DE LA MEMBRANA QUE, ACOPLADAS AL FENOMENO DE OXIDACION LIMITEN EL COLMATADO DE DICHA MEMBRANA (1) Y LLEVEN A LA MEJORA DEL CAUDAL Y DE LAS CUALIDADES FISICOQUIMICAS DEL FILTRADO. DADO EL CASO, COMPRENDE UNOS MEDIOS (10) DE INYECCION DE REACTIVOS QUIMICOS Y/O DE ADSORBENTES EN EL BUCLE DE FILTRACION.
