Study on Structure and Vacuum Membrane Distillation Performance of PVDF Composite Membranes: Influence of Molecular Weight and Blending
In this study, membranes were made from three polyvinylidene fluoride (PVDF) polymers individually and the blend systems of high (H) and low (L) molecular weight PVDF by phase inversion process. After investigating membrane casting solutions’ viscous and thermodynamic properties, the membranes so …

Theoretical and experimental investigation of membrane distillation
Invented in the 1960s, membrane distillation is an emerging technology for water treatment attracting more attention since 1980s. There are four configurations of membrane distillations including air gap membrane distillation (AGMD), direct contact membrane distillation (DCMD), sweep gas membrane …

Effects of Multi-walled Carbon Nanotubes (MWCNTs) and Integrated MWCNTs/SiO2 Additives on Polymeric PVDF Membrane for Membrane Distillation
… nanocomposite polyvinylidene fluoride (PVDF) membranes fabricated via phase inversion methods, and the effects of these additives on the structure and vacuum membrane distillation (VMD) performance of the membranes have been studied. With an appropriate amount of MWCNTs (2 wt.% to PVDF) …

Membrane distillation for high salinity desalination
Membrane distillation systems typically have low energy efficiency. Multistage membrane distillation (MD) systems can have significantly higher efficiencies than their single stage counterparts. However, multistage MD system design has received limited attention. In this work, the performance of a …
