Molecular weight cut-off

Concentration and purification of lignosulphonates (LS) present in spent sulfite liquor (SSL) obtained from the paper industry were carried out through ultrafiltration (UF). The salts of lignosulphonic acid, a product of acid hydrolysis of lignin, are a major component of technical LS. In respect of

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 by fouling materials calculate

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 the selection of ultrafiltration membranes with regard to efficiency
