| This study has investigated the capability of a creature originated calcium ceramics (CC) carrier including a scallop shell powder (SSP) with clay. The durability and adsorptivity of CC carrier in aqueous solution were strongly affected by the amount of SSP mixed with clay and the sintering temperature. The CC carrier made with higher amount of SSP had higher adsorptivity for ammonia and phosphorous, but the durability was low due to elution of a large amount of Ca2+from CC carriers in water solution. The carrier sintered at higher temperature had high durability, but the adsorptivity was extremely low. Consequently, the CC carrier mixed with 30 wt% SSP and sintered at 900 ℃ could maintain the stable water quality even after water dipping for 180 days, and could obtain high adsorptivity for ammonia and phosphorous.
