IMPROVEMENT OF DOC REMOVAL BY TWO-STAGE TREATMENT OF O₃ AND O₃/H₂O₂

Abstract

In order to removal of disinfection by-production THM precursor and reduction of TOC, two-stage treatment of ozonation and advance oxidation and BAC treatment were proposed. The result suggest that it was a difference on the removal of the DOC, THM precursor in ozonation and O₃/H₂O₂. And it was proven that the treatment effect raised the optimum combination. On the other hand, in the range of this study, it was proven that the O₃/H₂O₂ treatment was the optimum combination for the front stage treatment for ozonation.
