| Abstract |
This study was carried out comparing with ozone oxidation and photocatalytic degradation for removal of geosmin. In the change of pH, Ozonation, UV-Germicidal lamp and Halogen lamp irradiation and Halogen lamp/TiO₂ Powder was very slowly changing, but UV-Germicidal lamp/TiO₂ Powder was rapidly changed from 7.0 to 7.7 until 300min of irradiation time, and varied a little after. Geosmin degradation ratio was as following, UV-Germicidal lamp/TiO₂ Powder_((200㎎/L)) ≥ O₃$gt; UV-Germicidal lamp/TiO₂ Pw_((100㎎/L)) $gt; UV-Germicidal lamp $gt; Halogen lamp. The result of investigation of generated by-products were 3-Heptanone, two sort of aldehydcs and three sort of alcohols by ozonation. But It was not generated by photocatalytic degradation. |
