Abstract

Un sistema para producir agua de alta calidad a partir de agua salina y producir energía de dos corrientes acuosas de diferentes concentraciones en sal, cuyo sistema comprende: un elemento de membrana semipermeable (11) capaz de funcionar en el modo RO o en el modo PRO, cuyo elemento tiene una primera sub-cámara (13) y una segunda sub-cámara (15) separadas por un material de membrana semipermeable (17), y dicho elemento tiene también una entrada (19) y una salida (23) conectadas a dicha primera sub-cámara y los puertos primero y segundo (21, 25) están conectados a dicha segunda sub-cámara, un generador de energía de hidroturbina (31, 33), un primer medio de conducto (27) que conecta dicha salida de dicha primera sub-cámara de dicho elemento a dicha hidroturbina, un medio para conducir una corriente de alimentación líquida de agua de alta concentración en sal desde una fuente (53) de semejante agua salina bajo alta presión que incluye un segundo conducto (47) que conduce a la entrada de dicha primera sub-cámara, un tercer medio de conducto (41) que tiene una primera y una segunda bifurcación conectadas a dicho primer puerto de dicha segunda sub-cámara, un medio (39) para suministrar agua de baja concentración en sal a dicha segunda sub-cámara a través de dicha primera bifurcación (41a), mientras dicha segunda bifurcación (41b) sirve como un tubo de descarga para permeado acuoso, un medio (69) para extraer parte del agua de baja concentración en sal de dicho segundo puerto (25) de dicha segunda sub-cámara para conseguir arrastrar el flujo a lo largo de dicho material de membrana semipermeable, y un medio de control (65) para alternativamente hacer funcionar dicho sistema en un modo PRO productor de energía, en el cual dicha primera bifurcación (41a) operativamente se conecta a dicho medio de suministro de agua de baja concentración en sal (39) a dicho primer puerto (21) de dicha segunda cámara, o en un modo RO productor de agua de alta calidad, en el cual dicha segunda bifurcación de descarga (41b) está operativamente conectada a dicha segunda sub-cámara (15) para el flujo del permeado a través de la misma.
