New Delhi:Providing safer drinking water to those in need may become a little easier as Penn State researchers have developed a new desalination technique that removes salt from water using less energy than previous methods.
The "battery electrode deionisation" method improves upon previous techniques by avoiding a regeneration step by alternating the direction of the electrical current. Thus, instead of using 1.2 volts, researchers switched between -0.6 and 0.6 volts to get the same result.
"Globally, there is reduced access to fresh water,” said one of the researchers Bruce Logan, Professor at Pennsylvania State University in the US.
