Abstract

In this study the basic data were settled down to establish theory of membrane module and apparatus for measuring suspended solid per particle size. The theory and technique were different with the conventional weight method and light scattering method. For this purpose silica, dextran, kaolin, and PEG (polyethylene glycol) suspended solutions were filtrated through glass fiber membranes GF/C and GF/A on membrane module for measuring TMP (Trans-membrane pressure) changes using digital pressure gages. And the related equation between modified solution concentration and TMP change slope was derived from the TMP change experiments, and then suspended solid concentration of samples could be expected by the equation.

본 연구에서는 기존의 중량법과 광산란법과는 원리와 기술이 다른 입도별 부유물질 측정용 분리막 모듈 및 장치를 개발하기 위한 원리를 수립하기 위한 기초 자료를 확립하고자 하였다. 이러한 목적을 위하여, 이산화규소 및 덱스트란(dextran), 카올린(kaolin), PEG (polyethylene glycol) 부유용액을 대상으로 유리섬유 여과지 GF/C와 GF/A를 분리막 모듈에 장착하여 여과시키면서, 디지털 압력계를 사용하여 막간압력차(TMP, Trans-membrane pressure) 변화를 측정하였다. 모사용액의 농도와 TMP 변화율 기울기의 상관관계식을 TMP 변화 실험 결과로부터 구하여, TMP 변화 기울기로부터 시료의 농도를 예측할 수 있도록 하였다.
