Abstract

Granular activated carbon(GAC) adsorption is one of the best available technology to remove synthetic organic chemicals(SOCs) from water supplies and wastewater. In order to satisfy enviromental criteria and reduce GAC treatment cost, optimal study of reverse stratified tapered adsorber(RSTA) has been conducted. The RSTA was found to provide on increase in breakthrough time when compared to a conventional cylindrical adsorber(CA). Through the RSTA optimal experiment, optimal mean bed velocity was decided 19.10cm/min and optimal angle was decided RSTA($3.0^{\circ}$). Adsorption efficiency was increased with increasing activated carbon doses and the number of activated carbon layers.

활성탄 흡착법은 유해 유기화합물질을 처리하기 위한 최적기법이다. 강화되어 가는 각종 환경 기준을 만족시키고, 활성탄처리 비용절감을 위하여 RSTA의 최적화를 연구하였다. 실린더형 흡착탑과 RSTA의 비교실험에서는 동일 조건하에서 RSTA의 파과시간이 증가하였다. RSTA의 최적화를 위한 실험에서 최척 선속도는 19.10cm/min였으며, 최적각은 압력강하 실험과 최적 각도 결정 실험을 통해서 RSTA($3.0^{\circ}$)인 것으로 나타났다. 그리고 활성탄 주입량과 충전층수가 많을수록 흡착효율은 증가하였다.
