Abstract

The process of demineralizing natural water involves removing heavy metal ions and other pollutants from it. Given the current environmental trends, including environmental degradation and water pollution, there is a need to improve the efficiency of water treatment methods while minimizing the environmental impact. Reagent demineralization methods are widely used in water treatment systems, but they are often accompanied by high economic and resource costs, as well as additional pollution. A promising area is the combined use of reagent treatment with other demineralization methods, in particular the ion exchange method, which has been actively developing in recent years. This method is based on the stoichiometric exchange of ions between ion exchange materials and water.

The article deals with the issue of magnetic activation of the ion exchange process in the demineralization of natural waters. The analysis of existing water treatment systems using the method of ion exchange is carried out and the parameters that need to be improved are determined. A mathematical model for evaluating the efficiency of magnetic activation of cationite KU-2x8 is proposed. The analysis confirms the relevance of research in the field of intensification of ion exchange processes to improve environmental safety and efficiency of water demineralization. The results demonstrate the influence of such parameters as the initial water hardness and magnetic field intensity on the total exchange capacity of the cationite.
