NEW NANOFILTERS USE UP TO FIVE TIMES LESS ENERGY

摘要

Scientists at Nanyang Technological University (NTU Singapore, www.ntu.edu.sg) have invented a new type of nanofilter that could reduce the energy needed to treat wastewater by up to five times. Typically, for the last steps of water purification in a wastewater treatment process, an ultrafiltration (UF) membrane filters out small particles before a reverse osmosis (RO) membrane is used.
