Decreasing Iron (Fe) Contaminant from Ground Water for Water Treatment Processed by Dielectric Barrier Discharge Ozone Generator

Abstract

At the end of the decade, we have been entered to the bad condition for water quality. As well as we know that water is a primary demand for everyone. Ozone is a very reactive oxidant, and it can oxidize any parameters in water quality and then that parameters can be reduced. The principal of electrical discharge ozone generator can produce ozone when the compilation of electricity flow through the electrode, after that the discharge electrons will bound with free air which containing O2 so that O3 (ozone is formed). In the research, electrical discharge for ozone generator was made with high voltage variation are 12 kV, 13 kV, 14 kV. Next, ozone concentration that produced by this generator is contacted to the groundwater sample in Semarang which containing 5, 85 mg/litre iron and not yet required by World Health Organization International Standard for drinking water that is 0, 3 mg/litre. The result shows, the highest production ozone concentration by this generator is 33, 41 ppm and can decrease iron contaminant up to 23% from 5, 85 mg/litre to 4, 53 mg/litre. The lowest production ozone concentration is 2, 85 ppm, and can decrease iron contaminant up to 12% from 5, 85 mg/litre to 5, 15 mg/litre.
