Abstract

Un método y sistema para realizar mantenimiento en una membrana con propiedades semi-permeables y se usa en una osmosis retardada por presion PRO, teniendo la membrana un primer lado a alta presion y un segundo lado de menor presion. Una primera válvula o bomba (31, 41, 51; 61; 71; 81; 91) controlable por el tiempo está conectada entre una entrada (12) al lado a baja presion de la membrana (13') y una entrada (11) al lado a alta presion de la membrana (13'), dicha primera válvula o bomba operativa para entregar selectivamente un tapon (21) de un segundo tipo de agua (FW) al primer lado de la membrana para disminuir la concentracion de sustancia(s) disuelta(s) en agua de un primer tipo (SW) en el mismo, por lo cual creando una funcion de contracorriente de presion de PRO con el agua del segundo tipo (FW) desde el primer hacia el segundo lado de la membrana presurizada en dicho primer lado por suministro de alta presion de agua del primer tipo (SW) corriente arriba de dicho tapon (21) de agua del segundo tipo (SW).A method and system for performing maintenance on a membrane with semi-permeable properties and is used in a pressure-delayed osmosis PRO, the membrane having a first side at high pressure and a second side of lower pressure. A first time-controlled valve or pump (31, 41, 51; 61; 71; 81; 91) is connected between an inlet (12) to the low pressure side of the membrane (13 ') and an inlet (11) at the high pressure side of the membrane (13 '), said first valve or operative pump to selectively deliver a plug (21) of a second type of water (FW) to the first side of the membrane to decrease the concentration of substance (s ) dissolved (s) in water of a first type (SW) in it, thereby creating a pressure countercurrent function of PRO with the water of the second type (FW) from the first to the second side of the pressurized membrane on said first side by supplying high pressure water of the first type (SW) upstream of said water cap (21) of the second type (SW).
