The thesis is dedicated to find solution of actual problems of water treatment with the use of discrete-pulse input energy mechanisms. In the presented thesis the analysis of existing water treatment methods and detailed description of mechanisms which are realized during both thermo-vacuum treatment in the adiabatic boiling de-vice and high-frequency hydrodynamic oscillation superposition in rotary- pulsating devices was made. As a result of experimental researches it is established that the using of discrete-pulse energy input mechanisms is permissible for directly regula-tion of some water properties. In the theses the investigation of pressure release influence (from 98,1 to 5 kPa) upon a hydrogen indicator of water in temperature range from 293 to 373 K at experimental vacuum stand and during thermo-vacuum treatment was done. The dependence рН from temperature influence during thermo-vacuum treatment and dependence of waters рН from influence of high-frequency hydrodynamic oscilla-tions which are generated by rotary-pulsating devices with intercylinder backlashes 500 and 100 microns were established. The influence of thermo-vacuum treatment and high-frequency hydrodynamic oscillations on physical and chemical parameters of water is investigated. The most powerful changes: increase рН to 16 %, decrease of general hardness indicator to 37 % and alkalinity indicator to 27 %, amount of the solid residue to 35 %, electro-conductivity to 14,5 %, specific heat of evaporation to 3,5 %. According to the results of water treatment investigation by high-frequency hydrodynamic oscillation superposition was prepared aqueous-alcoholic mix for fur-ther use in industry on alcoholic beverage enterprise. The benefit from rotary-pulsating application is 12% in accordance with energy characteristics.
