Permeate flux hysteresis with transmembrane pressure in the gel controlling membrane filtration

The formation of the gel layer occurs during the clarification of any plant extract in membrane filtration processes. This study was aimed at investigate the impact of the increasing and decreasing transmembrane pressure cycle on the permeate flux of ultrafiltration (UF) and nanofiltration (NF) membranes when a clarified extract of olive mill solid wastes (OMSWs) is used as feed mixture. A hysteresis effect was observed for the selected...
