The effects of electrochemical, acoustic and superadditive pulsed discharge technologies on quality characteristics of various types of water

Abstract

This study aimed to evaluate the effect of three different techniques, namely electrochemical treatment, acoustic treatment and superadditive pulsed discharge technology, on three types of water. Electrochemical treatment technique was applied to the tap water, and its characteristics were compared against sanitary and hygienic requirements of the Russian Federation and the European Union. The results were comparable with both standards. Acoustic technology was used to treat water intended for industrial use, and its physical and chemical properties were analyzed in terms of industrial applicability. Additionally, food enterprise wastewater was treated by super additive pulsed discharges technology combined with the use of acoustic treatment. The results showed that the applied technique had a bactericidal effect, significantly reducing the rate of biochemical oxygen consumption and the content of fats, nitrites, nitrates, phosphates and ammonium ions in wastewater.
