| Abstract |
| Filter media have been used for various purposes such as water treatment facilities and methods. The purpose of this study is to evaluate and analyze the filter media chosen by their compositions. The subjects of the filtration experiments were zeolite, volcanic rock, foam glass and polyethylene. Zeolite and volcanic rock are sort of minerals that have specific characteristics. Foam glass contains void volume because it is made by foaming processes. Polyethylene is high molecular compounds. The results of experiments, the removal efficiency of SS is highest for foam glass showing 78.1%. COD and T-N removal efficiency is highest for zeolites showing 53.8% and 64.0%. The removal efficiency of T-P is highest for volcanic rocks showing 22%. In conclusion, selecting appropriate filter media based on the consideration of their characteristics is requested when applying water purification technology and water treatment facility with filter media. |
