Cross-flow filtration

Nanofiltration (NF) membranes retention depends on charge repulsion and size exclusion, combining the properties of ultrafiltration and reverse osmosis membranes. The molecular weight cut-off of two NF membranes was determined using cross-flow filtration of different molecular weights of non-ionized

The purpose of this study is to present a review of new ideas recently proposed in the field of supercritical fluid (SCF) and membrane coupled processes. The first item concerns CO2 recovery by membranes during a supercritical fluid extraction process. The aim is here to enhance the extraction proce
