In this study, a MWCNT(multi-wall carbon nanotube) was added to polysulfone(PSf) support layer to improve flux of TFC(thin film composite) RO(reverse osmosis) membrane. Two different kinds of MWCNT were used. Surfaces of some MWCNTs were modified hydrophilically through acid treatment, while those o...

NIPS 방법의 장단점은? | , 2009). NIPS 방법은 분리막의 형태와 기계적 특성을 제어하는데 유용한 방법이지만, 높은 표면 다공성을 얻는 것은 어렵다 (Guilen et al., 2011). | |
역삼투 공정이란? | 지난 수십 년간 인구 증가와 수질오염으로 인하여 담수의 수요는 지속적으로 증가하고 있으며, 역삼투 공정(reverse osmosis; RO)은 기수 및 해수로부터 안전한 음용수를 제공하기 위한 효율적인 담수화 기술로 각광받고 있다 (Zarrabi et al., 2016). | |
TFC RO막의 구성은? | 일반적으로 TFC RO막은 3개의 층으로 구성되어 있다. 바닥층은 부직포 지지체, 중간층은 폴리술폰 또는 폴리 에테르 설폰의 다공성 지지체이며, 최상층은 방향족 폴리아미드 필름으로 구성되어 있다(Geise et al., 2010). |
