Abstract

Способ и система для осуществления технического обслуживания мембраны, имеющей свойства полупроницаемости и использующейся в методе ограниченного давлением осмоса. Мембрана имеет первую сторону высокого давления и вторую сторону низкого давления. Регулируемый по времени первый клапан или насос (31; 41; 51; 61; 71; 81; 91) подключен между входным каналом (12), ведущим на сторону низкого давления мембраны (13'), и входным каналом (11), ведущим на сторону высокого давления мембраны (13'). Указанный первый клапан или насос избирательно доставляет пробку (21) из воды второго типа на первую сторону мембраны для снижения концентрации растворенных веществ (вещества) в воде первого типа, таким образом обеспечивая обратную промывку на основе ограниченного давлением осмоса водой второго типа от первой ко второй стороне мембраны, находящейся на указанной первой стороне под высоким давлением подачи воды первого типа выше по потоку от пробки (21) из воды второго типа.
