Due to the presence of higher concentration of ammonia nitrogen and organics in the raw water of Feng-shan reservoir located in southern Taiwan, traditional process of drinking water treatment is unable to serve a satisfactory result on procuring potable finished water for public uses. Since chlorine is often overdosed in the raw water and disinfection facility, the formation of chlorinated disinfection by-products have substantially limited the water from potable purpose. This research was divided into two phases. The first phase was focused on the long-term operation of a pilot-scale plant fabricated with conventional treatment units plus ozoantion and BAC processes to degrade organic substances and to control the formation of DBPs. The second phase was primarily aimed on the fundamental analysis on the characteristic of organic components and the effects of ozonation on those organics separated by XAD-8 resin into hydrophobic and hydrophilic forms.
