Abstract
Many methods and technologies including atmospheric cold plasma are being developed to control and modify water components such as electrical conductivity (EC) in order to manage and use water optimally. With this approach, plasma reactors were designed to control water electrical conductivity using oxygen atmospheric pressure discharge on the water surface. The results of measuring EC changes, after plasma exerting compared to before plasma by changing the reactor's design and the plasma interaction time with the water surface at 1-10 min during 1 min intervals showed that electrical conductivity decreased on the anode side of the anodic and cathodic plasmas in the two-vessel reactor in the short time of 1 min. In the following, the process changed and EC enhanced by increasing plasma exerting. In the single-vessel reactor, from 1-10 min, EC change was increasing, which was more in the cathodic plasma than the anodic plasma. In the two-vessel reactor of anodic plasma, the increase of changes was higher on the anode side than on the cathode side to 3 min and then reversed. In the two-vessel reactor of cathodic plasma, the increase of changes was higher on the cathode side than the anode side to 7 min and then reversed.
