This work focuses on sweeping gas membrane distillation process using flat sheet hydrophobic
PTFE membrane in a plate and frame module for desalination of sodium chloride solution. The
solution with 10, 25 and 50g/L concentrations used in the experiments. The effects of operating
parameters consist of feed temperature (45, 55 and 65oC), feed flow rate (200, 400 and
600mL/min), sweeping gas flow rate (4, 10 and 16SCFH) and feed concentration on the permeate
flux studied. The results show that the feed temperature has major effect on the permeate flux.
Increase of the feed concentration caused to reduce the permeate flux due to increase of
concentration polarization effect and reduction of vapor pressure difference. Moreover, sweeping
gas flow rate can increase the permeate flux due to reduction of vapor pressure in the permeate
side.
