Abstract
This paper presents a design for an electrodialyzer with upgraded spacer gaskets. Unlike similar designs incorporating cation- and anion-exchange membranes with resin granules and mesh gaskets, as well as a prototype with cooling tubes, the proposed design ensures more complete utilization of the chamber volume by reducing the number of guide holders. This eliminates stagnant zones and increases free space within the spacer gaskets. A staggered arrangement of the cooling tubes also facilitates more efficient heat exchange and changes in the solution flow direction. A process flow diagram for purifying industrial solutions using the developed electrodialyzer is presented. An analysis of operating costs, the economic efficiency of implementation, and the payback period for this technological process are provided. The proposed design solutions, implemented in the upgraded spacer gaskets, enable higher productivity, improved cooling, and, consequently, improved quality of the separated solutions.
