| Abstract |
| In this study, direct-coupled water treatment facilities with the capacity of 500 ㎥/day were installed and operated in Indonesia and Cambodia, respectively. In Indonesia, raw water was taken from the reservoir, and the water treatment plant for the process consisting of UF-AOP-GAC-Chlorination was installed horizontally. In Cambodia, groundwater was used as raw water, and the water treatment plant for the process consisting of UF-GAC-Chlorination was installed vertically. All water treatment plants were operated stably, and the produced water was suitable for drinking in terms of water quality standards. In the detailed evaluation of the unit process, the TMP of the UF process was stable at 0.35 ~ 0.4 kgf/㎠ when the raw water was groundwater with low turbidity, and chemical cleaning was unnecessary during the operation period of about 10 months; Meanwhile, in Indonesia where the turbidity of raw water is relatively high, the TMP was varying between 0.4 ~ 1.0 kgf/㎠ and chemical cleaning was required once a month. In addition, the differential pressure of GAC adsorber was maintained at a low level of 0.1 kgf/㎠ or less. Also, the electricity consumption was evaluated to be in the range from 0.23 to 0.26 kWh/㎥ for the operation of the Indonesian plant and 0.176 kWh/㎥ in Cambodia. The electricity consumption was significantly affected by the increase of TMP due to the turbidity of raw water, and the operating pressure needed to be minimized. |
