Abstract
FLUIDOS ACUOSOS COMO SOLUCIONES DE REACCIONES QUIMICAS O EFLUENTES DE PLANTAS DE PRODUCCION QUIMICA O PLANTAS DE TINCION, QUE CONTENGAN COMPUESTOS ORGANICOS Y SALES DE ACIDOS INORGANICOS POLIVALENTES, PREFERIBLEMENTE SULFATOS, SON AJUSTADOS A UN VALOR DE PH POR DEBAJO DE 4 CONCENTRADOS POR TRATAMIENTO DE MENBRANA Y SEPARADO POR UNA SOLUCION ACUOSA CONCENTRADA CON RESPECTO A LOS COMPUESTOS ORGANICOS Y UN PERMEADOR ACUOSO SUSTANCIALMENTE LIBRE DE COMPUESTOS ORGANICOS. BAJO ESTAS FUERTES CONDICIONES ACIDAS SE PUEDE ALCANZAR UNA CONCENTRACION EFECTIVA DE COMPUESTOS ORGANICOS SIN EL IMPEDIMENTO PRODUCIDO POR EL AUMENTO DE LA PRESION OSMOTICA PRODUCIDA POR LAS MENCIONADAS SALES. LOS CONCENTRADOS PUEDEN SER FACILMENTE ELIMINADOS Y LOS PERMEANTES, SUSTANCIALMENTE LIBRES DE COMPUESTOS ORGANICOS PUEDEN SER CANALIZADOS A UNA PLANTA DE DEPURACION PARA POSTERIOR TRATAMIENTO Y PURIFICACION.
