Solar-assisted distillation is considered promising to solve the freshwater supply for off-grid communities. In this work, a passive and flexible multistage membrane (F-MSMD) device devised produce via solar with latent heat of vapor condensation being recycled enhance its energy efficiency. By designing siphon effect, source water continuously wicked into evaporation layer concentrated brine f...

uv-induced grafting technique was used as a flexible method for surface modification of polysulfone (psf) ultrafiltration (uf) membranes in order to prepare hydrophilic nanofiltration (nf) membranes. flat sheet polysulfone (psf) ultrafiltration membranes were prepared via phase inversion method. n-methylene-2-pyrrolidone (nmp) and polyethylene glycol (peg) of three different molecular weights (...
