Abstract

A plasma process was used to treat natural organic matter in water which can produce the disinfection by products. Response surface methodology (RSM) is used to get a set of designed experiments to obtain optimal multi factor operating conditions for the lime stablization process. Response Surface Methodology explores the relationships between several explanatory variables and one or more response variables. It is a collection of mathematical and statistical techniques for empirical model building. The main objective is to optimize a response (operating watts of plasma process and reaction time) which is influenced by independent variables(UV254, DOC, THMFP). Operating watts of plasma process were 50 ∼ 140 W and reaction times were 2 ∼ 14 min, respectively. To obtain the efficiency of uv254 above 25.6 % and DOC above 60 %, THMFP above 50 %, the operation conditions of plasma process was 110 W and reaction time was 13.5 min, respectively.
