This study of the electrolysis reaction fillers and electrolytic treatment sludge generated by checking the status and properties of the sludge before and after electrolysis filler caused by a reaction to examine the water-soluble cutting oil sludge and organic matter removal mechanism of filling in the packed bed bipolar electrolytic reactor was to identify the characteristics. Delivery was analyzed using a SEM (scanning electron microscope) recording method for the filling material in the GAC surface characterization of the packed bed bipolar electrolytic reactor to look at the reaction of the waste water generated by the electrolytic removal reaction. Sludge generated in order to analyze the properties of XRD(x-ray diffraction) was analyzed using the device. The video of the GAC surface before and after the reaction was taken by SEM, it can be known indirectly the change between the voids in the GAC in figure before and after. Prior to the electrolytic treatment can be seen that there is some contamination between the pores, but it can be seen that after the treatment, rather than clean the pores of the GAC. This photograph of the surface after the electrolytic treatment, GAC is decomposed organic material adsorbed on the surface by dissolution of ions at the anode acting on bipolar electrolytic, it is corroded, it is possible to observe what happens. It was found to form iron oxide when analyzing the electrolytic sludge using XRD. Properties of the sludge generated after electrolysis, was composed primarily of oxygen and iron. These results wastewater treatment by filling in the electrolytic cell is that it indirectly proves to occur by electrolysis removal, it is considered to be able to demonstrate the deletion mechanism indirectly.

This study, changes in raw water quality is to indicate on the efficiency of ozone treatment of each pollutant as compared to derive the appropriate operating measures. The appropriate selection for injection rate of pre-ozone and did not inject pre-ozone assess changes in the water. When good water quality, you not injected of pre-ozone to evaluate the economic efficiency of electricity and put the most cost-effective ozone concentration were evaluated. Evaluation remove organic matter and chlorophyll-a concentration level in experiments with each factor of the water DOC> 2.5 ㎎ / L, THMFP> 70 ㎍ / L, Chl-a> 30 ㎎/ ㎥or less constant process, if you do not need to put pre-ozone showed little impact. It also does not put you in pre-ozone appropriate produce enough power rate savings was calculated as approximately 90 million won. Ability to remove organic materials and the ability to produce disinfection byproducts, and cost-effective decisions by considering the concentration of injection if pre-ozone 1 mg/L was investigated by the appropriate concentration of ozone injection.
