Introduction. Conducted research study is devoted to development of technological modes of desalination of natural mineral medical-table sodium chloride water for water treatment technologies in the production of beverages for athletes. Materials and methods. Samples of initial water and water that has been desalinated using the experimental installation with different modes were investigated. Measuring of temperature mode of crystallizer was carried out using temperature sensors and digital thermometer. Quality indicators of the water samples using Photometer Palintest 7500 and standard techniques were determined. Results and discussion. The influence of different factors of the process of freezing on the quality of desalinated natural mineral medical-table sodium chloride water "Kuyalnik" was investigated. The patterns of distribution of components of initial water between the frozen solid phase, and a concentrated solution in the process of freezing are identified. For the majority of the investigated factors order of traffic was such: Ca2+ > HCO-3 > (Na+ > Cl-) > (Mg2+ > SO2-4 > K+), and with a decrease in water salinity so: Ca2+ > SO2-4 > (Na+ > Cl-) > (HCO-3 > Mg2+ > K+). Summary of the study results allowed to recommend the following technological parameters of the carrying out the process of desalination of natural mineral sodium chloride water by freeze: operating temperature mode of crystallizer, which is changing in the process from -2 to -4 ° C, the concentration of carbon dioxide in the water at the beginning of the process of freezing - 3,7 g/dm³, duration of the desalination process (process without cooling) - 60 minutes, one step of freezing, melting of solid phase under ambient conditions without prior separation of the frozen solid phase. With such technological modes of the carrying out the process of freezing it is possible to obtain water with mineral composition, mainly with existing relevant recommendations to the mineral composition of beverages for athletes. Conclusion. As a result of scientific research an improved method for organizing the process of desalination by freeze was suggested.
