    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 method and system for performing maintenance on a membrane having semi-permeable properties and is used in a pressure retarded osmosis PRO, the membrane having a high pressure first side and second side of lower pressure. A time controllable first valve or pump (31; 41; 51; 61; 71; 81; 91) is connected between an input (12) to the low pressure side of the membrane (13′) and an input (11) to the high pressure side of the membrane (13′), said first valve or pump operable to selectively deliver a plug (21) of a second type of water (FW) to the first side of the membrane to lower concentration of dissolved substance (s) in water of a first type (SW) thereat, thereby creating a PRO pressure backwash function with the water of the second type (FW) from the first to the second side of the membrane pressurized on said first side by high pressure supply of water of the first type (SW) upstream of said plug (21) of water of the second type (SW).

    摘要： An automatic flushing and cleaning system for membrane separation machines such as reverse osmosis machines having plural modules or membranes. Cleaning may be by way of reducing the pressure to allow the membrane to relax, by the injection of air or inert gas to provide turbulence, and/or by injection of flushing liquid which may include chemical cleaning additives. Pumps, automatic valving, and pressure controls are provided, along with a complete timer operated electrical sequencing system whereby desired purging, flushing and cleaning cycles are automatically undertaken at periodic intervals or in response to one or more preferred conditions.

    摘要： A spiral wound membrane element and a method for cleaning a spiral wound membrane sheet are provided. The spiral wound membrane element comprising a perforated central tube; one or more membrane sleeves, each sleeve comprising two membrane sheets enclosed at two edges around a feed spacer sheet and wrapped around the central tube; a permeate carrier sheet attached to the central tube at a first edge opposite a second edge; and a seal on third and fourth edges of the permeate carrier sheet. The method comprises introducing two solution with different solute concentration to two sides of the spiral wound membrane sheet; establishing a concentration gradient between the first and second sides; communicating a first solvent from the first side to the second side to remove a foulant located on the second side of the membrane sheet and collecting a waste stream that contains the foulant.
