Скачать или смотреть A Cleaner Method for Turning Seawater into Drinking Water

Desalination plants are crucial for providing clean freshwater in dry regions. However, current filters used in reverse osmosis methods for converting sea water into drinking water are unable to handle high concentrations of brine waste produced by the filtering process. The leftover brine has to be dumped into waste ponds, or back into the ocean, which can be a pollution problem.

Assistant Professor of Chemical Engineering, Jovan Kamcev, and his lab have developed an electrodialysis device that uses ion selective membranes to separate salt from water. The membrane allows them to recover more clean water from the brine, and at the same time crystallize the salt from the water, eliminating excessive brine waste.
