hydrodynamic cavitation

The influence of the hydrodynamic cavitation on the absorption quality of water and water solutions of nitric acid as compared to NOx was theoretically justified and experimentally proved. The mechanism of acid formation as a result of this influence was identified. The industrial test at the Severodonetsk Azot Association PJSC was carried out by the irrigation of absorption column of activated water (after using cavitation device). This allowed to intensify the process in the absorption column and lower concentration of NOx from 0.11 to 0.08 % vol.

Disinfective action of physical-chemical effects accompanying hydrodynamic cavitation on the microorganisms sanitary indices in water has been studied. Disinfection kinetics was found to be dependent on the cavitation field characteristics and the microbes population. Based on the structural-morphological investigation of the E.coli bacteria it was found that antimicrobial effect is obtained due to the mechanical rupture of cells and chemical disinfection, which results from the hydroxyl radicals and hydrogen peroxide effect.
