Abstract

LAS UNIDADES MODULARES DE MEMBRANA DE OSMOSIS INVERSA (2,8) SE COLOCAN EN MULTIPLES ETAPAS CON UNA BOMBA ELEVADORA DE PRESION (7) COLOCADA EN EL CANAL DE FLUJO CONCENTRADO (4) ENTRE LAS UNIDADES MODULARES DE MEMBRANA DE OSMOSIS INVERSA (2,8), Y EL AREA TOTAL EFECTIVA DE MEMBRANA DE OSMOSIS INVERSA DE UNA UNIDAD MODULAR (8) ALCANZA DE UN 20 A UN 80% DEL AREA DE LA UNIDAD MODULAR PRECEDENTE (2). EL FIN DE ESTA INVENCION ES PRESENTAR UN APARATO Y UN METODO DE SEPARACION CON LOS QUE SE OBTENGA UNA SOLUCION DE BAJA CONCENTRACION A PARTIR DE UNA SOLUCION DE ALTA CONCENTRACION CON UN ALTO GRADO DE RECUPERACION, POCOS REQUISITOS DE ENERGIA Y UNA ALTA ESTABILIDAD.
