Solar desalination system for arid land agriculture

Friday, May 25, 2012 - 16:30 in Earth & Climate

A solar-powered system uses nanofiltration membranes to treat the local brackish water, resulting in high-quality desalinated irrigation water. The results indicate that irrigation with desalinated water yields higher productivity from water and inorganic fertilizers compared with current practices. Crops grown with desalinated water required 25 percent less irrigation and fertilizer than brackish water irrigation.
