Abstract

UN CARTUCHO PARA USAR EN LA OSMOSIS INVERTIDA, O FILTRACION, EL CUAL COMPRENDE UNA MULTITUD DE EMPAQUES (12), COMPRENDIENDO CADA UNO DOS HOJAS (14, 16) DE OSMOSIS INVERTIDA, O MATERIAL DE FILTRACION CON UN SEPARADOR (18) ALLI (JUSTO ENTRE). LOS EMPAQUES ESTAN DEVANADOS ALREDEDOR DE UNA CAÑERIA PERMEABILIZADA (10). CUANDO EL CARTUCHO ESTA EN USO NO EXISTEN SEPARADORES EN LOS PASAJES DE RETENCIÓN DE SAL, LOS CUALES SE DEFINEN ENTRE LOS EMPAQUES, PERO HAY SEPARADORES (18) EN LOS PASAJES IMPREGNADOS DE LOS EMPAQUES. EN LA FORMA PREFERIDA DE LA INVENCION EL CARTUCHO ESTA DEVANADO CON SEPARADORES (25) EN LOS PASAJES DE RETENCION, Y LOS SEPARADORES (25) SON SUBSIGUIENTEMENTE QUITADOS MEDIANTE EL RETIRO O LA DISOLUCIÓN DE ELLOS. LA MEMBRANA FORMA PARTE DE UNA INSTALACION, LA CUAL INCLUYE MEDIOS PARA IMPORTAR UN REMOLINO GIRATORIO EN EL AGUA DE ALIMENTACION, SIENDO ESTE REMOLINO SUPERIMPUESTO EN EL FLUJO AXIAL HACIA EL TERMINAL DE ENTRADA DEL CARTUCHO.A CARTRIDGE FOR USE IN THE REVERSED OSMOSIS, OR FILTRATION, WHICH INCLUDES A MULTITUDE OF PACKAGING (12), UNDERSTANDING EACH TWO SHEETS (14, 16) OF INVESTED OSMOSIS, OR FILTRATION MATERIAL WITH A SEPARATOR (18) THERE (JUSTICE BETWEEN). THE PACKAGES ARE WINDED AROUND A PERMEABILIZED PIPE (10). WHEN THE CARTRIDGE IS IN USE THERE ARE NO SEPARATORS IN THE SALT RETENTION PASSAGES, WHICH ARE DEFINED BETWEEN THE PACKAGES, BUT THERE ARE SEPARATORS (18) IN THE PASSAGED PASSAGE PASSAGES. IN THE PREFERRED FORM OF THE INVENTION THE CARTRIDGE IS WINDED WITH SEPARATORS (25) IN THE RETAINING PASSAGES, AND THE SEPARATORS (25) ARE SUBSEQUENTLY REMOVED THROUGH THE REMOVAL OR DISSOLUTION OF THEM. THE MEMBRANE IS PART OF AN INSTALLATION, WHICH INCLUDES MEANS TO IMPORT A ROTATING SWIRL IN THE FOOD WATER, BEING THIS SUPERIMPOSED SWIRL IN THE AXIAL FLOW TO THE CARTRIDGE INPUT TERMINAL.
