| Research Abstract |
The acceptable level of assimilable organic carbon (AOC) in drinking water for biological stability in water supply systems with minimized chlorine residual was determined as less than 11μgC/L. The AOC removals of biological activated carbon and nanofiltration varied largely depending on water temperature. The AOC removal of anion-exchange was also affected by the components of AOC. These technologies did not satisfy the acceptable AOC level, therefore the reassembling of current treatment processes for enhancement of AOC removal would be needed.
