영문 초록

In this study, the performance of powdered activated carbon(PAC) contactor located in the Hakya water treatment plant(WTP) was evaluated. The result of tracer tests showed that the plug flow portion was more than 70 %. According to the total organic carbon(TOC) data of target WTP, there were no clear evidence that the addition of PAC contributed to the removal of organics. However, the results of jar test, conducted with the raw water taken from the Hakya WTP, proved that PAC could remove dissolved organic carbon(DOC) to some extent when the proper velocity gradient was maintained. It was estimated that the production rate of Hakya WTP, defined as the ratio of the operating flow rate to the design flow rate, was only 50 %. Because of this lower production rate, the mixing intensity in the contactor is much less than the designed value and, finally, the performance of PAC contactor was much less than what was expected.
