The Application of Polypropylene Membranes for Membrane Distillation

Abstract

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 water [1-4]. The results of studies presented in the literature indicate that the MD process is not only an effective method for water desalination [1-3, 5], but also can be applied for wastewater treatment, especially when the salts concentration is high [3,6,7].
