Abstract The phase inversion procedure was used to prepare flat sheet membranes from PVDF. For vacuum membrane distillation (VMD) of seawater desalination, PVDF flat sheet membranes have been developed. The performance of the membrane was evaluated using an aqueous NaCl solution. To improve desalination flow, CNTs were added as a hydrophilic agent. PVDF membranes coated with carbon nanotubes are used in membrane distillation to provide superhydrophobic surfaces. The membrane covered with 4 g/lit CNTs had the maximum water flux (27 lit/m2.h) and the largest salt rejection (up to 99%). |
