چکیده مقاله:
In this study, the effects of gliding arc (G Arc)plasma system on the treatment of water have beeninvestigated experimentally. An AC power supply of15 kV potential difference at 50 Hz frequency wasemployed to generate plasma. Plasma density and temperaturewere measured using spectroscopic method. Thewater was contaminated with staphylococcus aureus(Gram-positive) and salmonella bacteria (Gram-negative),and Penicillium (mold fungus) individually. pH, hydrogenperoxide, and nitride contents of treated water were measuredafter plasma treatment. Decontamination of treatedwater was determined using colony counting method.Results indicate that G Arc plasma is a powerful and greentool to decontaminate water without producing anybyproducts.
