cavitation

The influence of the electric-discharge treatment on changes in the physical and chemical properties of water has been investigated. It is shown that the influence of the electrical discharge nonlinear bulk cavitation changes the structure of water as well as the formation of free radicals and hydrogen peroxide. The electric-discharge treatment increases the whiteness of wool due to the changes in water properties.

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.

The process of cyanobacteria complex treatment via obtaining of inedible fat, suitable for the production of biodiesel and biogas has been investigated. The prospective application of hydrodynamic cavitation to increase the efficiency of inedible fat extraction and biogas synthesis is shown. A comprehensive strategy for the cyanobacteria use in the energy and agricultural technologies is suggested.
