Effect of Bore Liquid Flow Rate on the Structure and Performance of Poly(vinyl chloride) Hollow Fiber Membrane

Abstract:

Poly (vinyl chloride) (PVC) hollow fiber membranes were prepared via non-solvent induced phase separation (NIPS), the effect of bore liquid flow rate (BLFR) on the structure and properties of the membrane were investigated. The results show that the prepared PVC hollow fiber membrane has a finger-sponge-finger-like structure, the thickness of the sponge-like intermediate layer decreases with the increase of BLFR. Both the inside diameter and outside diameter increase, while the wall thickness of the PVC hollow fiber membrane decreases with the increase of BLFR. The tensile strength and elongation decrease, the permeate flux increases, while the rejection of the particles decreases little with the increase of BLFR.
