In this study, in order to evaluate the water purification performance of media filter using shell recycling, specific surface area and water purification experiments were performed after fabricating a filter medium mixed with fine oyster shell powder, zeolite, cement, water, and effective microorganims (EM). A comparative experiment was performed on the amount of change in specific surface area and BOD, SS, and T-P according to the blending amount of the media filter material. When zeolite was added to the media filter using shell recycling, the specific surface area increased, which was twice that of the meida filter using shell recycling without the addition of zeolite. In terms of water purification performance, the removal efficiency of SS and T-P was very high regardless of the type of media filter, but the BOD removal efficiency was different depending on the blending amount of the media filter. The BOD removal efficiency of MF-3 (120 g of fine oyster shell powder, 40 g of zeolite, 40 g of cement, 140 g of water and 10 g of EM based on 350 g) was 86.8 % after 3 and 4 weeks. So it is suitable for use. If the media filter using shell recycling is developed using the optimal blending amount of the media filter obtained in this experiment, it is expected that it can replace the existing media filter and become a new utilization method of the neglected shells.
