Energy efficient seawater desalination and food processing

Reverse osmosis is a water purification method that uses a semipermeable membrane to desalinate seawater into drinkable water. While promising, it’s a relatively expensive technology.

UB researchers are addressing the problem by developing nanostructured materials with sub-nanometer pores that could enable the membrane to catch more salts as water passes through. The improved membrane is also designed to cut in half the amount of energy required to operate it.

The project’s principal investigators are Haiqing Lin, assistant professor in the Department of Chemical and Biological Engineering, and Bing Gong, professor in the Department of Chemistry.
