Abstract

Water quality has been deteriorated by the increasing amount of industrial waste water that is due to the better standard of living. In order to lessen the polluted water and substantially reutilize it at factories, a new method is needed. The plasma generator, which uses discharge current below 1,500 voltage and processes at extremely low temperature, has more strong oxidization than current method and an advantage of miniaturizing the apparatus in dealing with waster water by producing carrier gas at room temperature. This study were measured on the 3 kinds of waster water to the plasma generator for 120 minutes. As results, COD was almost decreased and removed in 15 minutes. The results suggest that the plasma generator can be used reduce COD and removal of color for various waster water, which can be reutilized as industrial water, It would be of benefit to the country like Korea in which qualified water is deficient.
