Fouling resistant

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

A new generation of chemically modified, FILMTEC* thin-film composite, aromatic polyamide membrane elements has been introduced that exhibits reduced rates for bacterial adhesion, longer induction periods before biofilm start developing, and extended operating times between chemical cleanings. When
