Ultrafiltration of protein solutions on ZrO2 membranes. The influence of surface chemistry and solution chemistry on adsorption

Environmental management of the residual brine of cod desalting. Quantification of mass transfer phenomena and determination of some parameters on the residual brine important for its treatment by membrane technology

“…Torres et al (2004) observed that changes in ionic strength or dissolution pH may affect the flux in the filtration of proteins, demonstrating the importance of environment on the properties of proteins and the behavior of permeate flux of this kind of dissolutions. In this sense, the presence of negative charges at the surface of the membrane prior to the cross-flow filtration may favor a low adsorption of fines particles, what is possible in ceramic membranes due to the amphoteric character of the zirconia (Cabero et al, 1999;Dumon and Barnier, 1992).…”

Limiting flux in skimmed milk ultrafiltration: impact of electrostatic repulsion due to casein micelles

“…The study was carried out using an experimental set-up previously described in detail [8]. The unit comprised a flow circuit (total volume close to 15 L but only 5 L of fluid were used) in which suspension was pumped continuously through a crossflow filtration membrane.…”

Protein Adsorption onto Metal Oxide Materials in White Wine Model Systems

“…The possibility of carrying out this treatment in a continuous mode by using exchange resins in model wine solutions has been studied (Gump and Huang 1999;Sarmento and others 2000). In the winemaking industry, the ceramic membranes (Hsu and others 1987;Dumon and Barnier 1992) are widely used as well.…”
