Thin-Film Composite Forward-Osmosis Membranes Reinforced on Woven Mesh and Nonwoven Backing Fabric Supports

摘要

Thin-film composite(TFC)forward-osmosis(FO)membranes were developed on different woven and nonwoven backing fabrics as support.Embedded backing fabrics have a significant effect on the membrane film sublayer by imparting porosity,membrane mechanical strength,and thickness.Woven and nonwoven backing fabric supports have been used for FO membranes cast on the commercial scale.There are also a few studies on the laboratory scale,but repeating them seems to be a challenge.The results herein show that TFC membranes with nonwoven incorporated substrates gain a higher water flux while keeping the specific reverse salt flux low.
