Dielectric barrier discharge(DBD) reactor and TiO2 were applied to disinfect the fresh water system containing bacteria. The occurence of electric dischage in DBD generates ozone and radiate unltraviolet light. The DBD reactor consisting of a quartz cylinder and a coaxial copper rod was immersed in the contaminared water. The selected bateria for the disinfection were Steptococcosis causing severe diseases in both freshwater and marine fishes from cultured and wild populations and Edwardsiella tarda, causative agent of edwardsiella septicaemia, which shows the critical lethality in intensive culture system. The performance of ozone, UV light, TiO2 photocatalyst, and the combination of the above methods was evaluated with a contaminated water. The results show that ozonation indicates the highest performance uo to 90% disinfection. |
