Flotation as a stage of cavitation-flotation technology for the treatment of aqueous heterogeneous media from dispersive solids and organic compounds

Integration of physical and physical-chemical processes is a principle that is inextricably linked with the development of modern technologies. Trends in the integration of technological processes are also characteristic for branches of water treatment and preparation. The combination of processes makes it possible to significantly increase the degree of sewage treatment, reduce the duration and energy intensity of the purification process, the costs to maintain optimal reagent, temperature, hydrodynamic regimes, etc.

Investigations of Cavitation Processes in Different Types of Emitters Using Sonochemical Analysis

The application limits of optical and sonochemical methods to determine the sizes of cavitation bubbles and their derivatives have been analyzed. The effect of cavitation fields generated using an ultrasonic magnetostrictive oscillator and jet hydrodynamic emitter on the parameters of their acoustic signals has been examined. The bubbles size depending on emitter type and parameters has been determined using sonochemical analysis. The character of the dependence was estimated according to Minnaert formula.
