Brackish Water Desalination by Air-Sweep Vacuum Membrane Distillation

Abstract:

An air sweep vacuum membrane distillation process was used to treat brackish water desalination. The only operating parameter of the apparatus is the sweeping air flow rate. The effect of sweeping air flow rate on desalination was observed. The produced/condensed water rate was about 2.5 g/h for the PP module. The conductivity of produced water was about 92 μs·cm^-1, the salt rejection was above 95%.
