| The pervaporation characteristics during the desalination of seawater were evaluated with pervaporative NaCl solutions (all experiments with NaCl concentration of 3.5 wt %) using a lab-designed and lab-assembled PV test apparatus. The pervaporation temperature was maintained at 25ºC, 40ºC, 60ºC, and 90ºC, and the feed pressure was maintained at less than 0.1 MPa depending on the PV temperature. For the pervaporation process during the desalination of seawater, the disc-shaped NaA zeolite membranes (diameter = 40 mm, thickness < 10 mm) were sealed in membrane modules. The circulating feeds were usually on the top surface of the self-supporting zeolite side such that the concentration polarization would be minimized. The water vapor was condensed and collected by liquid nitrogen trap. The concentrations of Na ions in the collected permeated solutions were analyzed using ICP to obtain the ion % rejection. |
