Establishment of High Efficiency Treatment System by High-Rate Ballasted Coagulation Sedimentation Process

Abstract

High-rate ballasted coagulation sedimentation process is able to form floes which have large specific gravity by using inorganic coagulant, organic polymer coagulant and microsand. Therefore, the space is compact and is able to reduce retention time of the whole process drastically. In this study, aiming at extremely compact water purification system, we are investing validity of both flow which combine ultra high rate coagulation sedimentation process with high rate filtration or microfiltration (MF).
