Molecular weight cut-off

1 - 3 of 3 results

The aim of this study was to evaluate how defects in a membrane surface can affect the molecular weight cut-off (MWCO) and the membrane permeability as they are traditionally defined. These two parameters are important criteria for th ...

Fouling characteristics of membranes with various molecular weight cut-offs (MWCO) were investigated. The effects of the molecular weights (MW) of humic acids and pre-treatment with PAC on membrane fouling were studied. It was found that the hydraulic resistance caused b ...

... (UF). The salts of lignosulphonic acid, a product of acid hydrolysis of lignin, are a major component of technical LS. In respect of molecular weight composition, LS represent a polydispersed system with a wide range of molecular weight distributions, from 200 to 150,000 Da. They have... for purification of LS. The LS present in SSL were estimated using different membranes (polysulphone, cellulose acetate, fluoropolymer) of varied cut-off sizes (1 K, 5 K, 10 K, 20 K, 25 K, 50 K and 100 K). Sharp cut-off membranes in between 20 K and 100 K Da show close rejections (80–84%). Th ...
