The aim of this study is to improve the technological schemes of demineralized water conditioning of autonomous objects, which provide automation of processes for obtaining drinking water from distillate at the autonomous objects and meet the requirements of compactness, reliability, energy intensity, environmental friendliness, and safety of service. As a result of the study, methods and materials for the mineralization, deodorization and disinfection of demineralized water were selected, the factors influencing the efficiency of the demineralized water conditioning processes were determined, and the optimal conditions for these processes were determined.
