| Research Abstract |
The combination of o ozone/ultraviolet treatment and ion-exchange treatment was applied to the reduction of DOC, ammonium ion, and chlorine demand. Our results showed that this new process is an effective way to control both hydrophobic and hydrophilic organic compounds and inorganic ions by ionizing hydrophobic and neutral compounds. Also, bromate ion, an oxidation byproduct, was effectively removed by anion-exchange treatment.
