Abstract

Water purification using a pulsed power discharge in water and ozone generated by dielectric barrier discharge (DBD) have been investigated experimentaly. Solutions contained Acid Red 1 and Acid Blue 64 were used as a specimen. A stacked Blumlein line pulsed power generator and wire-to-plane electrode was employed to generate the discharge in the water. The ozone of 1500 ppm cocentration was generated using pulse modulator driven coaxial cylinder DBD reactor and was injected to the solution. The electric powers consumed in reactors were 3 W and 8 W for water discharge and DBD, respectively. Acid Red 1 was successfully decolorized with 30 min of the ozonation process. The peak of the absorbance spectra shifted to higher value through the discharge in the water. The decoloration efficency of Acid Blue 64 by the ozonation process was about 1.1 times higher than that using the discharge in the water. The total organic carbone (TOC) removal was achieved to about 20% by the ozonation process.
