Abstract

The study was carried out to survey the removal characteristics of BPA using coagulation process by PAC and PAHCS. BPA removal for PAC and PAHCS chemical was similarly shown 20.9% and 22.9% with 5.8 Al mg/L and 10.2 Al mg/L, respectively. BPA removal efficacy was the highest at pH 6. The most removal by mixing time was 40 min in PAC and 20~30 min in PAHCS. When the powdered activated carbon 50 mg/L was added in coagulation process, more BPA was removed by 61%. These results will be appliable in the conventional water treatment plants for improvement of water treatment system.
