Abstract:
The thesis concerns the study results of the water acoustic treatment influence on its physico-chemical properties. Besides, the authors present the wastewater treatment results of food industry enterprises using superadditive pulse discharge technology with the acoustic treatment. The obtained results demonstrated that the studied technology had a bactericidal effect, reduced the biochemical oxygen consumption rate and the content of fats, nitrites, nitrates, phosphates, ammonium ions in wastewater significantly. The chemical oxygen consumption did not change compared to the control sample, apparently due to the electrode system elements (iron and copper) migration into water. The superadditive pulsed discharges technology of wastewater treatment using electroacoustic and acoustic methods also has great potential for application in the food industry, but the metal erosion problem is a factor limiting the industrial technology implementation currently.
