[Abstract]Calcium silicate briquette made from fly ash and lime was studied to improve the water purification capability by adding oyster shell powder into the starting materials. Compressive strength of the briquettes was linearly reduced to 75 MPa from 115 MPa with the addition amount of the oyster shell. On the other hand, the bulk density, porosity, and water absorption, did not change significantly. The microorganisms derived from the oyster shell was applied on the surface of the briquettes for a purification test. After 72 hours, BOD value was decreased from 1000 mg/L to 115 mg/L. Since only a little difference of BOD value was observed with adding the oyster shell powder, purification performance is not considered by the capabilities of the microorganism of oyster shell, but by those of the briquette.
