| Research Abstract |
A novel pulse discharge system for water treatment was constructed, which can be easily submerged in water. It consists of a stainless screw bar used as the high voltage electrode, a stainless spiral wire used as the earth electrode, and an air disperser placed under the electrodes. The frequency of discharge was drastically decreased with increase of solution conductivity, and no discharge plasma was observed when the conductivity was1200 μS/cm. The decomposition of indigocarmine and linear alkylbenzene sulfonate (LAS) was also demonstrated with this novel discharge plasma reactor. Inactivation profiles of microorganisms by submerged style pulse discharge system in bubble water were investigated. We have confirmed the inactivation of Escherichia coli and Bacillus subtilis spore by this system.
