Nanotech water desalination

We can see more examples everyday of how extensive the application on nanotechnology can be. New ways for water desalination and purification found at UCLA.

Engineers develop revolutionary nanotech water desalination membrane

Researchers at the UCLA Henry Samueli School of Engineering and Applied Science today announced they have developed a new reverse osmosis (RO) membrane that promises to reduce the cost of seawater desalination and wastewater reclamation.

"The nanoparticles are designed to attract water and are highly porous, soaking up water like a sponge, while repelling dissolved salts and other impurities," Hoek said. "The water-loving nanoparticles embedded in our membrane also repel organics and bacteria, which tend to clog up conventional membranes over time."
