The article is devoted to the creation of import-substituting chemical water treatment systems using nanocomposite cation exchangers, the production of which is currently being investigated at the Institute of Nuclear Physics of the Academy of Sciences of the Republic of Uzbekistan. The experience of operating similar systems shows that in hot climates, the cation exchanger is rapidly contaminated with microorganisms, which leads to the subsequent destruction of cation resin granules and dramatical reduction of the lifetime/operation of expensive chemical water treatment systems. Unlike foreign analogues, the authors of the article use a new technology for modifying strongly acid cation exchangers with silver nanoparticles, which provides bactericidal properties, and thereby significantly increases the life of chemical water treatment systems in climatic conditions of Central Asia. Currently, the developed chemical water treatment systems with nanocomposite cation exchangers are actively being applied in Uzbekistan, in particular to mini-boiler houses built as part of the modernization program of the heating system of the republic.
