Breakthrough in reverse osmosis may lead to most energy-efficient seawater desalination ever Making fresh water out of seawater usually requires huge amounts of energy. The most widespread process for desalination is called reverse osmosis, which works by flowing seawater over a membrane at high pressure to remove the minerals.   Now, Purdue University engineers have developed a variant of the process called “batch reverse osmosis,” which promises better energy efficiency, longer-lasting equipment and the ability to process water of much higher salinity. It co...
