Abstract

The effect of humic acid on the simultaneous removal of nitrate and phosphate was investigated in a micellar-enhanced ultrafiltration (MEUF). At the low molar ratio of cetylpyridinium chloride (CPC) to contaminants, the removal of nitrate was lower to 50％ by 100 ppm of humic acid due to the competition for binding on micelles. At the molar ratio higher than 3, however, the removal of nitrate was over 80％. Phosphate was removed over 80% at the molar ratio higher than 1. The CPC and humic acid were rejected over 99 ％ by UF membrane. The flux did not decrease by 100 ppm of humic acid but rather slightly increased since the humic acid adsorbed on the membrane made the membrane more hydrophilic. As a result, humic acid did not diminish the performance of MEUF in the simultaneous removal of nitrate and phosphate.

본 연구에서는 미셀 한외여과(Micellar-enhanced ultrafiltration, MEUF)공정으로 질산성 질소와 인산을 동시에 제거할 때 휴믹산이 공정에 미치는 영향을 살펴보았다. 계면활성제/오염물의 몰 비가 1인 경우, 질산성 질소는 미셀 표면에 휴믹산과 경쟁적으로 결합을 하기 때문에 그 제거율이 50%로 감소하지만, 몰 비 3 이상의 계면활성제를 첨가하였을 때에는 80% 이상의 제거율을 유지하였다. 반면 인산의 경우에는, 몰 비 1 이상의 CPC 농도에서 질산성 질소와는 달리 휴믹산이 존재하지 않는 경우와 비슷한 수준인 80％ 이상의 제거율을 보였으며, 이때 CPC와 휴믹산의 제거율은 거의 99％ 이상 이었다. 또한 100 ppm농도의 휴믹산은 MEUF공정에서 플럭스 감소에 영향을 미치지 않고 오히려 조금 증가시켰으며, 이는 막에 흡착한 휴믹산이 막의 친수성을 증가시켜 투과율을 높이기 때문인 것으로 판단된다. 이를 통해 휴믹산은 질산성 질소 및 인산을 동시 제거하는 MEUF 공정에서 제거효율을 저하시키지 않음을 확인하였다.
