Abstract
Studies on the electrolytic concentratoin of sea water were carried out with homogeneous ion exchange membranes, and the following results were obtained.
1) With the rise of the current density, the concentration of the produced brine and its yield increased in an approximately linear relationship, respectively.
2) The amount of the produced salt increased in proportion to the current density.
3) The current efficiency on the electrolytic concentration was independent of the current density and remained substantially constant.
4) With the rise of the current density, the voltage of cell increased proportionally, and in this case the amount of electric power necessary to produce the concentrated brine containing 1 ton of salt also increased.
