PVA

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

Fouling resistant membranes (NF and RO membranes) were prepared by coating a neutral polyvinyl alcohol (PVA membrane). The PVA-coated membranes showed a lower surface charge and roughness. By using the NF and RO membranes, dyeing process wastewater (influent, coagulated water and effluent) was recyc

Sorption and pervaporation experiments were carried out with PVA/PAA cross-linked membranes for the separation of azeotropic methyl tert-butyl ether and methanol mixtures. The influence of the PVA/PAA ratio and liquid mixture composition were investigated. With increasing PAA content in the membrane
