A team of scientists from the National University of Singapore (NUS) has come up with a novel approach to treat industrial wastewater using electricity as a reagent for purification. The method can remove up to 99 per cent of hard-to-treat organic compounds found in various types of industrial wastewater. The NUS-developed system operates on low electrical power and does not generate secondary waste, such as sludge, that requires further costly residual waste processing such as incineration.
