Abstract: The co-generation of hydrogen 11 from water 8 produced during pressure driven water desalination/filtration processes, such as reverse osmosis, forward osmosis, pressure retarded osmosis or ultrafiltration. A small part of feed, raw saline solution and/or permeate involved in a desalination/filtration processes is subjected to electrolysis thereby splitting the water to produce hydrogen. This is achieved by the provision of novel RO type semi-permeable membranes and UF type membrane that incorporate electrodes 9, 10 within the membrane to allow splitting of the water via electrolysis.

Abstract: Disclosed herein is a system for cleaning feed water of variable quality, the system including an inlet for selectively delivering feed water to one or other of at least two feed chambers, each feed chamber having a delivery pipe for delivering feed water to a reverse osmosis or nanofiltration, a pump to deliver the feed water from one of the chambers through its associated delivery pipe to the reverse osmosis or nanofiltration to create a concentrated feed stream and a product water stream, return pipes for selectively returning the concentrated feed stream to one or another of the at least two feed chambers, a product water outlet for removal of the product water, and switching mechanisms and/or switchers for switching the delivery of the concentrated feed stream between the selectable return pipes upon detection of a predetermined reduction in efficiency within one or another of the feed chambers.
