This study was performed to develop ceramic material to be able to eliminate phosphorus and nitrogen in water. Olivine was found to remove phosphorus in aqueous phase, which was demonstrated by Lee and Choi.1) The nitrogen removal using zeolite has been demonstrated by many researchers.2,3) Hence, utilization of mixed-typed material of Olivine and Zeolite is expected to achieve simultaneous elimination of phosphorus and nitrogen in water. In this study, the removal efficiencies of T-P(Total phosphorus) and T-N(Total nitrogen) were investigated using ceramic material in batch reactor system, which was produced by incinerating after mixing Olivine and Zeolite with different ratio. The highest removal efficiency of phosphorus was achieved under the condition of 1: 2 mixing volume ratio of Olivine to Zeolite. The phosphorus of 93.6% and 97.4% (as T-P) was removed for 0.5hr and 4hr, respectively. For the nitrogen, the nitrogen removal efficiencies of 93.6% and 97.4% (as T-N) were obtained under the condition of 1:6 mixing volume ratio of Olivine and Zeolite.
