New reverse-osmosis membrane to improve desalination

Increasing numbers of countries turning to desalination plants to bolster dwindling water supplies with most new facilities making use of reverse osmosis technology. Unfortunately these systems are susceptible to clogging and membrane damage, which places higher energy demands on the pumping system and necessitates costly cleanup and membrane replacement. Now researchers have unveiled a new class of reverse-osmosis membrane that resists the clogging that typically occurs when seawater, brackish water and waste-water are purified.
