Modification of commercial ultrafiltration and nanofiltration membranes by uv-photografting technique for forward osmosis application

We introduce a novel approach to modify conventional pressure-driven membrane by ultraviolet (UV)-photografting technique for forward osmosis application. Both ultrafiltration polyethersulfone (UFPES) and nanofiltration polyethersulfone (NFPES) membranes were modified using two grafting parameters n...
