Paper Title:
Comparative Study of Ozone Alone and Catalytic Ozonation for Transformation of Natural Organic Matter in River Water
  Abstract

Ozone alone and catalytic ozonation of natural organic matter had been carried out in semibatch model reactor. The experimental results demonstrated that ozonation alone and catalytic ozonation are equivalent with minimization of natural organic matter(NOM), with the removal rate of TOC, UV254 about 7 % and 50 % respectively. But it is a promising method for changing the molecular weight and specially for enhancement of biodegradation. The AOC in river water was 233 ug L-1, which increase up to 325 ug L-1, 677 ug L-1, 633 ug L-1 in ozonation alone, catalytic ozonation (H2O2) and catalytic ozonation (ZnO) after 30 minutes reaction respectively. Through the research, it can be conclued that catalytic ozonation-BAC may be an promising way for water treatment.
