"The object of this investigation was to study the use of non-wettable porous membranes for simultaneous heat transfer and mass transfer of water from a hot salt solution stream to a cold distilled water stream, the streams being in countercurrent flow separated by the membrane. This type of mass transfer was achieved in the experiments, and mass and heat transfer coefficients were measured.
The membranes studied in this work were made of fiberglas treated with Teflon dispersion and aluminum sulphate. The fiberglas membranes yielded desired results. Empirical correlations were proposed which predict values of heat and mass transfer coefficients close to the experimental values.
In this study mass transfer rate per square foot ranged from 0.175 to 0.674 lb/(hr ft2). The range of the heat transfer coefficient was from 1.45 to 11.5 Btu/(hr ft2 °F) and that of the mass transfer coefficient was from 0.061 to 0.113 lb /(hr ft2 inch of Hg). These results have demonstrated the possibility of producing pure water from a salt solution by evaporation through porous membranes with countercurrent flow"--Abstract, page ii.
