In this study, variation of effluent of residual chlorine concentration was estimated from bench scale distribution reservoir test according to variation of flow and baffle condition. According to the bench scale test results, when the flow rate was an unsteady state, difference between the case of no-baffle in the reservoir and the case of two-baffles in the reservoir became less than the condition when the effluent flow was in a steady state. Consequently, the results are caused by the flow rate variation. Thus, the baffle is less effective than a clearwell of steady state condition.
