Our goal

Membrane: .Development of high rejection reverse osmosis (RO) membranes that can achieve high removal of (1) micropollutants and (2) pathogens, which ultimately helps to reduce reliance on the following advanced oxidation process (AOP).

Analysis.: Development of online analytical methods for continuously determining (3) micropollutant concentrations and (4) microbial counts that can ensure membrane integrity for their removal.
