Scientists from the National University of Singapore have developed an electrochemical approach to treat industrial wastewater using electricity as a reagent for purification. NUS believe the method can remove up to 99 per cent of hard-to-treat organic compounds found in different types of industrial wastewater.
Furthermore, the system is claimed to operate on low electrical power and does not generate secondary waste, such as sludge, that requires further residual waste processing such as incineration.“Despite the great advances in wastewater treatment technologies, the removal of refractory organic compounds remains a costly and challenging process...
