Membrane distillation for the purification of water was proposed. The obtained distillate was the demineralized water with the electrical conductivity in the range of 1.3 - 2.5 mS cm-1. The polypropylene membrane wettability during long-term investigations has been performed. A gradual decline of the permeate flux, from 650 to 390 dm3/m2d was observed as a consequence of the fouling phenomenon. The CaCO3 deposit formed on the membrane surface caused a decrease of the membrane permeability and a partial membrane wetting.
