Abstract
공급수가 원판틀형 모듈에 잘 분포될 수 있는 역삼투형 하우징(HY)을 개발하여 설계 제작하였으며 상용화된 Rochem(RC)시스템과 투과성능을 비교하였다. 자체 개발한 HY시스템은 RC시스템에 비하여 투과유속이 약간 떨어지는 반면, NaCl 배제율은 전반적으로 높았다 원판틀형 모듈인 type A, B, C에 대한 투과유속 및 배제율을 NaCl, sucrose 및 butanol 수용액으로 측정하였다. NaCl 및 sucrose의 경우, type C, A, B의 순으로 투과성능이 우수하였으나 butanol의 경우는 type B, C, A 순이었다. Type A에 대한 type C의 butanol 투과유속은 농도가 감소할수록 그리고 28 bar 범위내에서 운전압력이 증가할수록 향상되었다. The reverse osmosis membrane housing(HY) was developed for excellent distribution of a feed solution, and the separation performance was compared with the commercialized Rochem(RC) system. The permeation flux of HY system was a little lower than that of RC system. On the other hand, the NaCl rejection ra4io was generally higher. Also, the permeation flux and rejection ratio for type A, B and C modules(disc plate and frame type) were measured using NaCl, sucrose and butanol solutions. The separation performance of type C module for NaCL and sucrose solutions was the most effective, and then those of type A and B were followed, respectively. However, the separation performance for butanol solution was type B, C and A order. The flux improvement ratio of type B to A increased as butanol concentration decreased or operating pressure increased up to 28 bar.
