✦ Synopsis

In order to determine the quantitative characteristics of the temperature effect upon physical and chemical properties of solutions and ion-exchange membrane8 at low ealt concentration8 in the influent water, experimental studies were carried out using laboratory and full-scale equipment. The relationships of the temperature effect8 on the diffusion layer depth, on the value of critical current density and on the parameters of flow hydrodynamics in the experimental cell were obtained. These relationships are taken as a basis for the economic-mathematical model for the optimization of operating parameters and technological scheme8 of high temperature electrodialysis apparatus. Using this model computer-aided technical and economic eetimates were carried out along with the comparison of alternative8 under variable initial conditions.
