Water desalination system works up to several times faster than others
August 7, 2012 Editor 0
(Phys.org) — As the world population increases and fresh water sources become scarcer, many people will likely rely on technologies that convert salt water to fresh water to meet their most basic needs. Currently, the most common method of water desalination is reverse osmosis, a process that removes water molecules from salt water, leaving salt ions (sodium and chlorine) in the leftover brine. But an alternative method called capacitive desalination (CD), also known as capacitive deionization (CDI), has the potential to operate with greater energy efficiency, lower pressures, and no membrane components compared to reverse osmosis.
