The Application of Polypropylene Membranes for Membrane Distillation-Juniper Publishers
Authored by Marek Gryta Abstract Microporous hydrophobic membranes are applied in membrane distillation. During a long-term of module exploitation, a part of the pores is filled by water, and the membrane wetting causes that the industrial implementation of this process is hindered. Several investigators achieved promising results using the polypropylene membranes formed via TIPS method for various applications of membrane distillation. Keywords: Membrane distillation; Polypropylene membrane; Hydrophobic membrane Abbrevations: MD: Membrane Distillation; PTFE: Polytetrafluoroethylene; PP: Polypropylene PE: Polyethylene; TIPS: Thermally Induced Phase Separation Introduction Membrane distillation (MD) is an evaporation process of water through non-wetted porous membranes. In this process the salts and other non-volatile compounds present in the feed water are retained and the quality of produced distillate is close to distilled w...
