Self-sustained webs of polyvinylidene fluoride electrospun nanofibers at different electrospinning times: 1. Desalination by direct contact membrane distillation

Preparation and characterization of PVDF flat-sheet membranes for direct contact membrane distillation

“…It is found that the prepared flat-sheet composite membrane in this work have comparable or even better performance than commercially available flat-sheet membranes for the desalination of salt solution. The permeate flux of the PVDF nanofibrous membrane fabricated by Essalhi and Khayet [37] was higher than the flux obtained in this study. But it should be noted that the PVDF nanofibrous membrane was prepared via electrospinning, and there was no ''blind pore'' in the membrane and the porosity was also higher than that of the membrane prepared through coating and wet phase inversion process.…”

Electrospun Nanofibrous Membranes for Liquid Filtration

“…The flux rate was comparable to those of commercial MF membranes (5-28 kg/m 2 h) at temperature differences ranging from 25 ı C to 83 ı C [98]. Essalhi and Khayet demonstrated the feasibility of ENMs for desalination by using a direct contact membrane distillation system (DCMD) and analyzed the PVDF ENMs thickness effect on the DCMD performance [99]. The PVDF ENMs in DCMD had a permeation flux of 15.2 10 3 kg/m 2 s and a salt (NaCl) rejection ratio of 99.39 %, with a feed temperature of 80 ı C. After 25 h, the PVDF ENMs stayed dry and the distilled water permeate flux lost less than 5 %.…”

Electrospun Nanofiber Membranes and Their Applications in Water and Wastewater Treatment

“…Essalhi and Khayet [92] examined the effect of thickness of PVDF nanofibers on characteristics of ENMs and performance of a DCMD. The thicknesses of the fibers they produced were between 144.4 and 1,529.3 μm.…”
