Abstract
Advanced processes such as ozonation or activated carbon filtration (ACF) in water treatment plants have been used in Korea since 1994. At present, seventeen drinking water treatment plants are currently operating. This survey compares the treatment performance of advanced processes in eight plants which have comparable water quality data. The three parameters (DOC, $UV_{254}$, and $KMnO_4$ consumption) of water quality were selected as an indicator of treatment efficiency. The treatment efficiency of ozonation and ACF processes was found to vary with large deviations in each plant. Treatment efficiency of DOC, $UV_{254}$, and $KMnO_4$ consumption by post ozonation ranged from 3 to 11%, 6 to 33%, and 12 to 28% respectively. On the other hand, for ACF, treatment efficiency of DOC, $UV_{254}$, and $KMnO_4$ consumption ranged from 7 to 38%, 8 to 48%, and 16 to 66% respectively. These large deviations indicate the advanced processes of water treatment plants to be further optimized.
