Abstract

This study evaluated and optimized the UV/ chlorine process for natural organic matters (NOMs) removal using response surface methodology (RSM). The effects of both the primary and secondary interactions of the reaction variables, including initial chlorine concentration (X1), UV radiation time (X2) and pH value (X3), were examined. A satisfactory prediction response model (R2=0.999) was obtained, indicating the reliability of the methodology. The optimum condition obtained by CCD were 4.5 mg·L-1 initial chlorine concentration, 7 min UV radiation time and pH 6.7. Under the optical condition, the maximum TOC removal was 48% and TOC concentration was only 2.6 mg·L-1. The UV/ chlorine process as a novel AOP has many advantages for drinking water treatment, in terms of less chemical consumption, shorter reaction time and simpler technology.
