Abstract
This study shows the development of a produced water treatment system using flocculation and magnetic separation, and the improvement of the prediction formula on floc residual rate to evaluate magnetic separation performance. Previously, magnetic separation conditions were determined based on a number of experiments on various types of influent that depends on wells. Therefore it took time substantially to design specifications for each system. A simple design process diagram has been established by considering influential factors to magnetic separation conditions and conducting simple experiments using synthetic water. The developed prediction formula can realize speedy and effective proposals on the system customized for each site.
