Abstract
In this study, the effects of gliding arc (G Arc) plasma system on the treatment of water have been investigated experimentally. An AC power supply of 15 kV potential difference at 50 Hz frequency was
employed to generate plasma. Plasma density and temperature
were measured using spectroscopic method. The
water was contaminated with staphylococcus aureus
(Gram-positive) and salmonella bacteria (Gram-negative),
and Penicillium (mold fungus) individually. pH, hydrogen
peroxide, and nitride contents of treated water were measured
after plasma treatment. Decontamination of treated
water was determined using colony counting method.
Results indicate that G Arc plasma is a powerful and green
tool to decontaminate water without producing any
byproducts.
