Abstract

Membrane fouling control in water treatment may be the main obstacle for wider implementation and lower cost. A novel fluorescent spectroscope sensor device for membrane fouling integrity monitoring has been developed and evaluated in this study. PSf membranes for water treatment has been fabricated with three types of organic fluorescent materials, OB, FP, KCB. The fluorescent signal from membrane surface was analyzed throughout the filtration process. It was found that the fluorescent signal due to the membrane fouling decreased and the developed device is reliable for membrane fouling monitoring.

수처리 분리막 공정에서 막 오염 제어 기술은 현장 적용 기술 및 경제성 확보에 있어 매우 중요하다. 본 연구에서는 형광 나노 입자 및 형광 분광 분석법을 도입함으로써 수처리 분리막 공정에서 막 오염 정도를 실시간으로 측정 모니터링 할 수 있는 센싱 기술을 개발하고자 하였다. 막 오염 정도를 모니터링 할 수 있는 분리막 제조를 위해 세 종류의 형광물질 OB, FP, KCB를 담지한 다공성 polysulfone (PSf) 비대칭 막을 제조하였다. 형광 분광 분석 시스템을 이용하여 분리막 표면에서의 오염 정도를 실시간으로 측정한 결과, 형광 물질을 첨가한 막은 막 오염이 진행됨에 따라 형광 신호가 크게 감소함을 보여 막 표면 오염층의 모니터링 분석이 가능함을 확인하였다.
