Optimization of the regeneration of the sodium-cation ion-exchange filter

Abstract

A new methodology has been developed for determining the volumetric coefficients of internal mass transfer according to the results of an experimental study. The values of volumetric coefficients of internal mass transfer were calculated and their dependence on the technical characteristics of the regeneration process of the sodium-cation exchange filter under dynamic conditions was established. A computer model of the process of regeneration of the sodium-cation exchange filter in nonequilibrium and non-stationary conditions in the form of a computer software package (“Regeneration-1”, “Regeneration-2”), recommended for scientific, design, commissioning and operating organizations, relevant industries. For the first time, the task of optimizing the ion-exchange nonequilibrium regeneration of the sodium-cation exchange filter as a separate stage of the filter cycle was posed and solved. The analytical dependence of optimizing the specific consumption of NaCl salt for nonequilibrium regeneration of the sodium-cation exchange filter as a separate stage of the filter cycle is obtained.
