Aplikasi Plasma Lucutan Berpenghalang Dielektrik Pada Pengolahan Air Sumur : Pengaruh Terhadap Ph, Kesadahan, Dan Total Coliform

Abstract

Has conducted research on dielectric barrier discharge plasma applications configured with spiral – chylindrical electrodes to generate ozone free air source. Purpose of this study was to determine the effect of ozone dissolved in water quality through pH, hardness ( CaCO3 ), and total coliform in the waterin the eastern part of the village Gemah. Electrodes used in this study has a diameter of 3 cm and a length of 15cm. Plasma generation using AC voltage with a voltage of 7 kV. Air flow velocity used 5,5 L/min with a volume of water that will be treated with ozone as much as 1 liter. Dissolved ozone free air is obtained by incorporating into the DBD reactor, out of the reactor, ozone is formed, and flowed into the water. Dissolved ozone concentration were determined by varying the time and use a constant voltage. The result showed the concentration of dissolved ozone diminishing increments. pH values tend to be fixed and not affected by ozone treatment of water. Water hardness value decreased slightly and the number of total coliform as a whole are likely to remain
