US researchers develop lean energy membrane-based system
Researchers at Humboldt State University, USA are developing a portable prototype pressure retarded osmosis (PRO) seawater desalination (SWRO) system that exploits the osmotic pressure differential between brine waste from SWRO and wastewater. In turn the system deploys the PRO energy in the SWRO.

Scaling-up and piloting of pressure-retarded osmosis
When Statkraft abandoned its pilot pressure retarded osmosis project it took much of the momentum out of the industry s then accelerating progress. This was despite the reported successes of Japan s giant Mega-ton project. The authors here outline the chief challenges and the prevalent views of the future among leading figures in the industry.…
