A model plant having 50 pairs of cation and anion exchange membrane of 0.7m<SUP>2</SUP> effective area was operated throughout the year for the concentration of sea water. The change in the temperature of raw brine (9-30°) affected the rate of electro-phoretic water transport, and it caused a change in the concentration of produced brine. Power consumption per unit weight of concentrated NaCl was also affected by temperature, but as far as the brine of identical concentration is produced, it does not vary so much because current density should be raised in summer and lowered in winter to keep the concentration steady.
