New Reactor Configuration for Maintaining Stable Plasma Discharge during Treatment of Water with Increased Electrical Conductivity

The setup for water treatment by plasma discharge in the cavitation field is improved. The new reactor configuration allows for treatment of water with increased electrical conductivity and mineralization (up to 5 g/l). This is achieved by increasing the cavitation area of the reactor by creating an idle area, which plays the role of additional resistance and reduces the leakage current resulting from ionic conductivity under increased mineralization. The use of the new reactor design significantly expands the scope of the potential practical application of this setup. Increased total mineralization usually characterizes water used in agriculture for watering plants and soaking seeds. During the work, the setup was also tested under the conditions of an aeroopic system for germinating Mamluk spring barley seeds. It is determined that the use of water treated with plasma discharge increases the content of vitamin C by 29% and total nitrogen and phosphorus by 25% and 13%, respectively.
