Abstract: Demineralized water is necessary to obtain a quality product at the enterprises, without itit is impossible to comply with technological regulations. The article deals with the analysis of industrial water, changes in its quality due to seasonality and discharge of wastewater into water bodies and the method of bringing these indicators to standards using the method of ion exchange. Ion exchange is an effective method of desalting water, however, the ionites that are used in it must be restored (regenerated) after the complete filter cycle.In this work, the parameters of the quality of process water by ion-exchange method were determined. In this work, the parameters of the quality of process water by ion-exchange method were determined. The water parameters are determined, which can be concluded that the resin must be regenerated. These indicators include: gesture-bone, iron ions, sodium, chloride and chemically absorbed acid genus (COD). The variants of regeneration are analyzed, their advantages and disadvantages are revealed. On the basis of the conducted experiment, it was determined how long the filter with resin can work and how fully it is regenerated, as well as the advantages of transition from direct-flow regeneration to counter-flow. It was found that the resin is not completely regenerated. Despite the fact that the ionites have not fully recovered, their further use is allowed, but with a smaller filter cycle (the volume of water passed before the withdrawal of resins for regeneration).

Key words: ion-exchange method regeneration filtercycle ionites demineralized water
