Abstract

The neutral polymer, poly (vinyl alcohol) (PVA), was coated onto polyamide (PA) thin film composite reverse osmosis (RO) membranes. And then these membranes were investigated for the model foulants, bovine serum albumin (BSA), humic acid (HA), and sodium alginate (SA) whether there are aome improvement. As the operating pressure increased with 2, 4, 8 atm for BSA, HA and SA 100 ppm in feed solution, the fouling phenomena was worse for both none and PSSA coated membranes. The fouling occurred in the sequence of BSA > HA > SA due to the interactions between PVA snd functional groups of foulants, and on the other hand the fouling reduction was observed in the order of HA > BSA > SA. The observation of scanning electron microscopy photographs showed the same trend. As a result, there should be the improvement of fouling phenomena for the PVA coated RO membranes and the case of HA was shown distinct.

본 연구에서는 폴리아마이드 역삼투 복합막 표면에 중성 친수성 고분자인 poly (vinyl alcohol) (PVA)를 코팅한 후 모델 오염물질인 bovine serum albumin (BSA), humic acid (HA), sodium alginate (SA)에 대하여 파울링 개선 효과가 있는지를 알아보고자 하였다. 고분자의 파울링 유도를 위해 모델 오염물질인 BSA, HA, SA 등이 100 ppm으로 용해된 공급원액을 2, 4, 8 atm 조건에서 PVA 코팅된 막과 코팅되지 않은 막에 대하여 파울링 실험을 수행한 결과. 압력이 증가함에 모든 오염물질에 대해서 파울링은 심화되었다. 파울링 심화 현상은 BSA > HA > SA의 순으로 일어났으며, PVA가 코팅된 막에 대해 파울링 개선효과는 HA > BSA > SA의 순으로 나타났다. 전자현미경 사진 결과에서도 같은 경향을 보여주고 있다. 결국, PVA가 코팅된 역삼투막은 어느 경우에서나 파울링 개선효과는 뚜렷하게 있었으며 HA의 경우에서 가장 두드러졌다.
