| ABSTRACT |
|
This study investigated the removal characteristics of various micro organic compounds by low-pressure nanofiltration membranes comprised of
disinfection by products and pharmaceutically active compounds. The experimental removal of micro organic compounds by low-pressure nanofiltration
membranes was compared with the transport model calculations, which consist of diffusion and convection terms including steric hindrance
factor. The selected molecule from the disinfection byproducts and pharmaceutical active compounds showed a much lower removal than polysaccharides
with a similar molecular size. However, the difference between model calculation and experimental removal of disinfection by-products
and pharmaceutically active compounds could be corrected. The correlation of Ks with solute radius was further considered to clarify transport phenomena
of micro organic solutes through nanofiltration membranes. |
