Abstract
Recently to control refractory dissolved organic matter which is recognized as a problem of water quality management in public water area, it is strongly requested the strengthening of process for T-P which is the growth limitation factor. So we have researched the characteristic of filteration through composite filtering system by direct filteration system adapted floating media to treat phosphorus treatment of second sewage disposal water and particle pollutant. In this research we could confirm the increase of phosphorus removal efficiency by glowing bigger particle floc than existing filteration process through slow mixing of composite direct filteration system. And also as a result of an experiment of filteration efficiency for each coagulants, PACl was approved as the most appropriate coagulants.
Key Words
Composite direct filtration system, Floating media, Filtration velocity, Slow mixing, T-P
