Membrane distillation (MD) is a promising desalination technology for water recovery from high-salinity solutions such as RO brine. Despite its great potential, MD has not been industrially realized because this technique generates a lower flux than reverse osmosis processes and exhibits a lower ther

Membrane wetting and fouling were studied using hollow-fiber polyvinylidene fluoride (PVDF) membranes to concentrate reverse osmosis (RO) brine in a direct contact membrane distillation (DCMD) process. The effect of the operating conditions, such as the feed temperature, the flow velocity and the feed

In this paper we present a new method to prepare organic–inorganic hybrid PVDF/Si membranes by adding tetraethyl orthosilicate (TEOS) into the polyvinylidene fluoride (PVDF) casting solution. During the membrane coagulation in acid bath (pH = 1), the TEOS was hydrolyzed and polymerized, and silicon–

Poly (vinyl alcohol) (PVA) is an excellent membrane material for preparation of hydrophilic ultrafiltration (UF) and nanofiltration membranes. But its chemical constitution and water solubility infer the disadvantage of easier degradation and elimination after use. This study focuses on the modifica
