Abstract

SE DESCRIBE UN PROCESO PARA LA PRODUCCION DE AGUA PURA. EL AGUA EN BRUTO O AGUA SUMINISTRADA SIMILAR SE LLEVA AL DISPOSITIVO (1) DE ACONDICIONAMIENTO CON AL MENOS UNA MEMBRANA (4) SEMIPERMEABLE. PARTE DEL AGUA EN BRUTO PASA A TRAVES DE LA MEMBRANA (4) COMO AGUA PURA, BAJO LA FUERZA DE ACCIONAMIENTO DE UNA DIFERENCIA DE PRESION, Y EL AGUA EN BRUTO RESTANTE QUE FLUYE POR MEDIO DE LA MEMBRANA ABANDONA EL DISPOSITIVO (1) DE ACONDICIONAMIENTO COMO UN CONCENTRADO. PARA TENER EN CUENTA UN ENSUCIAMIENTO EXCESIVO DE LA MEMBRANA (4) Y PARA CONSEGUIR UN TIEMPO DE FUNCIONAMIENTO TAN LARGO COMO SEA POSIBLE Y UNA VIDA DE SERVICIO DE LA MEMBRANA ADECUADA, LA DIRECCION DE FLUJO DEL AGUA EN BRUTO QUE FLUYE POR MEDIO DE LA MEMBRANA (4) ES INVERTIDO PERIODICAMENTE O CAMBIADO. UN DISPOSITIVO (1) DE ACONDICIONAMIENTO PARA LA PRODUCCION DE AGUA PURA DISPONE AL MENOS DE UNA MEMBRANA (4) SEMIPERMEABLE Y AL MENOS (2) ABERTURAS (10,11) DENTRO DE LA ZONA (5) DE AGUA SUMINISTRADA O AGUA EN BRUTO. UNA ABERTURA ESTA DISEÑADA COMO UNA ENTRADA DE AGUA PARA EL SUMINISTRO DE AGUA DE AFLUENCIA O AGUA EN BRUTO A LA MEMBRANA (4) Y LA ABERTURA EXTERIOR ESTA DISEÑADA COMO SALIDA DE AGUA PARA EL CONCENTRADO. EL DISPOSITIVO (1) DE ACONDICIONAMIENTO DISPONE AL MENOS DE UNA SALIDA DE AGUA PURA EN SU ZONA (6) DE AGUA PURA. LA CARACTERISTICA DEL DISPOSITIVO DE ACONDICIONAMIENTO ES QUE LAS ABERTURAS (10,11), DENTRO DE LA ZONA (5) DE AGUA SUMINISTRADA O AGUA EN BRUTO, ESTAN SERVIDAS DE FORMA ALTERNATIVA Y PERIODICAMENTE COMO ENTRADAS O SALIDAS DE AGUA.
