【 摘 要 】

The aim of this research was to develop technique to disinfect bacteria in water with chlorine. Response surface methodology (RSM) was applied for investigating the experimental design for disinfection the Klebsiella terrigena (Raoultella terrigena TISTR 1568). There were 20 experiments involving the three investigated variables of chlorine concentration, pH and disinfection time that were studied on R. terrigena TISTR 1568 to optimize the condition for disinfecting the R. terrigena TISTR 1568 to 99.9% death. Design of experiment was performed by application of 5-level-3-factors central composite design in order to study the optimum condition for disinfecting the R. terrigena TISTR 1568 to 99.9% death. The investigated results showed that the optimum condition was 1.2 ppm of chlorine concentration, at pH 7 and 5 min of disinfection time.
