불소이온을 함유한 폐수로부터 불소 이온제거는 입자상 알루미늄 충전복극전해조를 사용하여 실험적으로 검토하였다. 실험결과 불소제거효율은 전압, 전해시간, 전극간격, 충전율 등에 의존적이었다. 10V와 15V의 전압으로 30분간 전해했을 때 불소제거효율은 각각 77, 89%이였다. 전하부하 $35.0 F/m^3$에서 70%의 불소이온 제거효율은 70%이었고 55.0, $85.5 F/m^3$에서 불소제거효율은 각각 85, 92%였다.

The removal of fluoride ion from wastewater containing fluoride ion was experimentally investigated using a bipolar packed bed electrolytic cell with granular aluminium. The experimental results showed that the removal efficiency of fluoride ion depended upon the applied cell voltage, electrolysis time, distance of electrode and volume of packed bed loaded with granular aluminium. When the sample solution electrolysed during 30 min under the conditions of 10V and 15V cell voltage, removal efficiency of fluoride ion was 77% and 89%, respectively. Fluoride ion removal efficiency was 70% for a $35.0 F/m^3$ charge loading and 85% and 92% for a 55.0 and $85.5 F/m^3$ charge loading, respectively.
