Abstract
An energy-efficient disinfection or sterilisation of contaminated liquid, such as water contaminated with viruses or microbes includes an asymmetric configuration of a cavitation nozzle made from dielectric material that enables the formation of a single, stable cavitation bubble of a large volume. A low-pressure gaseous plasma is continuously formed inside the cavitation bubble by electrodes to prevent contact of the metallic electrode with liquid water and Ohmic heating of the contaminated water. The electrodes are connected to a high voltage power supply. The power supply enables formation of a continuous stable gaseous discharge inside the cavitation bubble and radicals and radiation useful for destruction of viruses to the levels below the current US EPA standard in few minutes, while the temperature of liquid water remains practically unchanged. Use is not only for hospitals and pharmaceutical companies but the food industry and agriculture as well.
