摘要： A method of cleaning a fouled RO membrane in a module for RO separation, the membrane having feed side and permeate side, the foulant accumulating at the feed side. The cleaning method comprises: feeding concentrated saline solution to the feed side of the RO membrane under the high gauge pressure of the normal RO separation process; feeding dilute saline solution to the permeate side of the RO membrane under higher pressure than the permeate pressure of the normal RO process, so that a net driving differential ΔPN is directed to the feed side, whereby the solvent is being sucked from the permeate side to the feed side, penetrates into the interface between the membrane and the accumulated foulant, and separates the foulant from the membrane surface; and withdrawing the concentrated saline solution together with the separated foulant and the penetrated solvent from the feed side of the RO membrane.

摘要： A vertical desalination element comprising a vertical pressure vessel (PV), membrane elements, and a loading mechanism for loading the membrane elements into the vertical PV. The vertical arrangement of the membrane elements and the vertical PV enhances air bubble percolation, increases construction efficiency and allow handling heavy membrane elements. The membrane elements may be loaded singly or groupwise, from either the upper or the lower end of the vertical PV. The loading mechanism may comprise various appliances and devices for supporting and securing the membrane elements, and may apply various ways of loading and releasing the membrane elements.
