PROBLEM TO BE SOLVED: To provide a filter press type diffusion dialysis device for increasing recovery capacity of an acid and alkali per one tank, and preventing damage of an ion exchange membrane by dilution heat, by increasing the number of recovery chamber and liquid discharge chamber in the tank.SOLUTION: A filter press type diffusion dialysis device 100 is a form for arranging a fastening frame on both ends, by normally incorporating 2-10 pieces of stacks 5 into a fastener 20. A membrane and a chamber frame of normally 20-200 pairs, and desirably 40-120 pairs are used in the respective stacks 5. A large number of pairs incorporated into a tank are divided by the stacks 5, so that many membrane groups can be arranged between a cushioning frame 1 and a cushioning frame 3, and the membrane area per one tank of the tank can be remarkably increased. Maintainability is improved by being formed in a stack structure in this way.SELECTED DRAWING: Figure 1 |
