Performance improvement of PVDF hollow fiber-based membrane distillation process

PVDF Hollow Fiber and Nano Fiber Membranes for Fresh Water Reclamation using Membrane Distillation

Polyvinylidine fluoride (PVDF) hollow fiber and nanofibrous membranes are engineered and successfully fabricated using dry-jet wet spinning and electrospinning techniques, respectively. Fabricated membranes are characterized for their morphology, average pore size, pore size distribution, nanofiber diameter distribution, thickness and water contact angle. Direct contact membrane distillation (D...

Correlated Effect of Air Gap and PVP Concentration on the Structure and Performance of PVDF Ultrafiltration Hollow Fiber Membrane

Polyvinylidene fluoride/polyvinylpyrrolidone (PVDF/PVP) hollow fiber membranes were fabricated by dry-jet wet-spinning process. The correlated effects of the air gap length and PVP concentration ((1) the air gap length effect at the low and high PVP concentration in the dope solutions, as well as (2) the effect of the PVP concentration at the same air gap length) on the cross-section structure ...
