PURPOSE:To enable the execution of rapid and efficient desalting, etc., with a simple construction to concentrate and recover a concd. liquid down to the threshold concn. of an electrodialysis regardless of the concn. of an aq. soln. CONSTITUTION:The concn. processing device for the aq. soln. has an electrodialyzer which is alternately arranged with cation exchange membranes 103 and anion exchange membranes 104 via chamber frames 105 and is alternately formed with concentrating chambers 106 and desalting chambers 107 by both these ion exchange membranes 103, 104 and chamber frames 105. The device has a means 110 for circulating the concd. liquid to the concentrating chambers 106 and a means 120 for recovering the increasing volume-component of the concd. liquid by operating the electrodialyzer. |
