Forward osmosis (FO) membrane technology is an emerging separation process that employs the natural osmotic pressure gradient to drive water transport through semipermeable membranes. This methodology ...

A new study conducted at MIT has examined the potential of pressure-retarded osmosis (PRO), a technique that generates electricity from the difference in salinity between two pools of water separated ...

Reverse osmosis (RO) is a type of water filtration system that forces water through a thin, semipermeable membrane or filter to remove impurities. In homes with RO water systems, water is pumped ...

A study published in ACS Energy Letters reveals that researchers have developed a semipermeable membrane capable of harnessing this osmotic energy from salt gradients to generate electricity. In ...

An enormous amount of energy dwells where rivers meet the ocean. Harnessing this energy—released when fresh and salty water mix—requires expensive porous membranes that can control the flow of ions.
