Abstract:
RO membrane technologies have made great progress in last 50 years. In seawater and brackish water desalination field, both energy saving and water quality improvement have been two major subjects. Advanced membranes are still demanded to achieve lower cost, lower energy consumption and higher water quality. In order to obtain further excellent performance, Toray has been executing fundamental research for RO membranes on investigating physical and chemical properties through PALS(Positron annihilation lifetime spectroscopy) study, Computer chemistry and TEM (Transmission electron microscopy) analysis, which has resulted in the advanced RO membranes with high flux, high rejection, excellent chemical durability.
