RESULTS OF THE INITIAL PERIOD OF DEVELOPMENT OF HYDRODYNAMIC WATER PURIFIER TYPE "CYLINDER IN CYLINDER" IN THE INDUSTRY
An overview of the initial period of development of hydrodynamic water purifiers from mechanical impurities is given. The main problems that the developers and designers of these purifiers had to face are considered. Possible solutions to these problems are described. Prospects for further directions of improving water purification systems, based on hydrodynamic purifiers, are analyzed.
