Electromagnetic resonance vibrocavitator is designed for cavitation processing water-based liquids. Such cavitators are effective when used for cleaning water pools of biological pollution, and for improving the structure of drinking water. The authors have designed electromagnetic resonance vibrocavitators for the first time, their constructive structure is protected by a patent on an invention. Electromagnetic resonance vibrocavitator action for disturbance of cavitation in liquids relates to cavitation equipment of chemical-engineering processes. It can be used for water treatment, including disinfection of drinking water, wastewater chemical, and food processing plants from a variety of contaminants, including biological. This equipment belongs to a group of physical and chemical methods. Cavitation initiates and activates the oxidation-reduction reactions in liquids splash of large amount of energy arising in fluid cavitation bubbles. The design of the vibrocavitator is quite universal, which creates prerequisites for successful use as conduits for small cross-sections ranging from one to three inches, and industrial water supply pipes with diameter up to 250-300 mm. In our opinion, vibrating cavitator would particularly be for the biological decontamination of drinking water. The simplicity of its design and service provides the stage for the installation of the cavitator in pipelines pumping water in swimming pools, water parks and public use reservoirs, along with the disinfection of water. Because of the gap cavitation bubbles form active chemicals, hydroxyl radicals, ozone, hydrogen peroxide and others. In fact, this technology is a combined method of refining exposure to water. The main units of cavitator is a stator with electromagnets oscillating breaker anchor with cavitation and resonance elastic system connecting the anchor of the stator. The performance of cavitation water treatment pools is 1.5-2.0 m3 / hr., the degree of effluent milk business ranges from 97 to 98 % with performance up to 100 l / h. Performance effluent from brewery yeast is 200-250 dm3 / h. To conclude, a new method of low-frequency vibration resonance cavitation phenomena (processes) in water-based liquids and equipment for its implementation are designed. A distinctive feature of the process of cavitation resonance is energy impact on liquid flow cavitation during their oscillation frequency.
