Abstract

To evaluate the performance of a bipolar packed bed cell (BPBC) filled with granular aluminium, the experiments were carried out in two groups as batch and continuous processes. In a batch process, removal efficiency of total phosphate (T-P) was 88% in case of electrolytic treatment of phosphate solution, T-P 10 mg/L at 6 V during 3 h by BPBC filled with granular aluminium. In a continuous process, residual T-P concentration was about 2 mg/L in case of electrolytic treatment of phosphate solution, 10 mg/L at 6 V, HRT 3 h by BPBC filled with granular aluminium. Break-through point was observed after running for 120 h at hydraulic retention time (HRT) of 3 h.

입자상 알루미늄 충전복극조의 성능을 파악할 목적으로 실험은 회분식과 연속식으로 진행하였다. 입자상 알루미늄 충전복극조를 이용하여 T-P 농도 10 mg/L인 인산염 함유 용액을 6 V에서 3 h 회분식으로 전해처리 한 결과 T-P의 제거율은 88% 이었다. 입자상 알루미늄 충전복극조를 이용하여 T-P 농도 10 mg/L인 인산염 함유 용액을 6 V에서 HRT를 3 h으로 하여 연속식으로 전해처리 한 결과 T-P의 농도는 2 mg/L이었다. HRT 3 h으로 고정하여 전해처리 할 경우 120 h 처리 후 파과점을 관찰할 수 있었다.
