Optimum Design of Residual Treatment Process Based on Characteristics of Raw Water

Analysis of design parameters of residual treatment process at eight model water treatment plants, which were located in the four major watersheds, showed that there were large differences between those design parameters and the actual conditions. In this background, a new procedure was proposed and applied to the Chungju water treatment plant as an example of the optimum design of residual treatment process based on the characteristics of raw water. In this design example, a filter backwash recycle system consisting of a surging tank and sedimentation basin was newly proposed for more safe recycle of spent backwash water. It is expected that the design procedure proposed in this study would be estimated as a meaningful attempt to develope new design procedure for the domestic water industry.
