초록

To obtain design and operating parameters for advanced water facilities, pilot test consisted of ozonation and GAC filtration was conducted at midstream of Nakdong River. Even though the concentrations were very low, 62 chemicals were detected above $0.005{\mu}g/L$ in raw water. In the preozonation, natural organic matters which could produce THMs and organics such as phenols and amines were effectively removed. The performance of TOC removal of GAC filtration with ozonation was better than GAC filtration alone and adsorption capacity of GAC adsorbers were ranged 3~6mg-TOC/g-carbon. And also the life of GAC adsorber for removing TOC was predicted more than 1 years if ozonation is introduced. This indicates that biological degradation of organics happened in GAC filters. Most organics detected at ppt level were removed below detection limit by GAC filtration with ozonation. These results show that ozonation and GAC filtration are the reliable and safe process for organic contaminants and chlorinated byproducts control at Nakdong River.
