20120118826 | DESALINATION SYSTEM - A desalination system based on forward osmosis, that uses a draw solution at high osmotic and gauge pressures to generate mechanical power from the expansion of the draw solution due to water extracted from feed water through a semi-permeable membrane. The extracted water is produced during the regeneration of the draw solution. The generated power may be used to desalinate additional feed water, e.g. via reverse osmosis, such that most power needed for the reverse osmosis is supplied from the expanding draw solution, e.g. via a work exchanger. After power recovery, partly dilute draw solution may be used to extract additional water from feed water via an additional forward osmosis module. | 05-17-2012 |
20120285886 | RECIPROCAL ENHANCEMENT OF REVERSE OSMOSIS AND FORWARD OSMOSIS - Periodically operating a forward osmosis (FO) semi-permeable membrane element in reverse osmosis (RO), to yield product extraction on a feed side of the membrane, to flush out a concentration polarization (salt concentration of the feed side and dilution of draw solution on the draw side) across the membrane. Utilizing treated waste water to generate the flushing solution of low osmotic pressure, and gauge pressurizing the flushing solution to the gauge pressure of the draw solution to keep a constant gauge pressure of the solutions. FO process is interrupted every 5-20 minutes for a 10-60 seconds long flushing RO process, thereby increasing the FO throughput five fold and recovering power from the increased throughput, i.e. from the osmotic pressure of the brine. | 11-15-2012 |
