Objectives
This project aims to develop a high-performance and highly-selective nanofiltration (NF) membrane for the precise separation of minerals and micropollutants in drinking water treatment. Existing NF membranes are mainly designed and optimized for monovalent/divalent ions separation, which results in their relatively high rejection of minerals (e.g., > 80% for Ca2+ and/or Mg2+). In contrast, they often show insufficient rejection of toxic micropollutants at trace concentrations (e.g., 20 Lm-2h-1bar-1, together with low rejection of minerals (e.g., 90%). This project will open a door for the development of asymmetrically selective NF membrane for drinking water treatment.
