Recently, PFASs (Per- and Polyfluorinated Substances), which are forever chemicals, were
designated as water quality monitoring items and started to manage in Korea. In this study, an
integrated model for PFASs removal prediction was developed and verified in the drinking water
treatment system. The integrated model was composed of the case of the post-ozone-GAC process,
which is most applied to water treatment plants in Korea. A total of 10 types of PFASs, including 3
perfluorinated sulfonate (PFSA) and 7 types of perfluorinated carboxylic acid (PFCA), were selected
for removal model development and evaluation. To verify the removal model, the spiking test was
performed in a pilot plant with a daily capacity of 30 m3, which combined the standard water
treatment process with post-ozone and GAC (Granular Activated Carbon) as the advanced water
treatment. According to the results, it was verified that the integrated model can predict the removal
efficiency of the pilot plant. However, the experimental results showed that the removal prediction
model was reliable under limited operating conditions.
