cavitation

Встановлено, що ефективно знешкодити рідкі відходи виробництва олефінів, які
містять сполуки головно аренового та дієнового рядів, можна, обробляючи їх у
кавітаційних полях. Використання як реагенту розчинів натрію гіпохлориту, які є
відходами суміжного виробництва, дає змогу інтенсифікувати окиснення органічних
сполук. Оптимальне співвідношення між рідкими відходами виробництва олефінів та
натрію гіпохлоритом було визначене залежно від зміни величини редокс-потенціалу
реакційної системи. Показано, що окиснення органічних сполук відбувається через

Push-pull vibratory electromagnetic cavitator of resonance action consists of two electromagnets, an elastic system connecting their stators and anchors, and two cavitation breakers located in the flowing liquid in the form of soundboards with holes which fluctuate in antiphase. High degree of biological disinfection of water with the productivity of approximately 3.5 m3/h at its continuous supply is provided due to the combination of magnetic and cavitation effects.

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.
