Membrane ultrafiltration in multipass hollow-fiber modules

, 1998
Rising fluid velocity in the fiber tubes of a hollow-fiber module has two conflicting effects. One, the decrease in resistance to permeation due to reduction in concentration polarization, is good for ultrafiltration, while the other, the decrease in ...

Enrichment and concentration of proteins by ultrafiltration [PDF]

, 1990
Disclosed are ultrafiltration processes for the enrichment and concentration of selected proteins from protein conaining fluids. Illustratively, IgG is concentrated from whey by means of multiple ultrafiltration passes , using a metallic oxide ...

[Ultrafiltration in heart failure].

, 2012
In patients with heart failure fluid overload is clinically evident as systemic and/or pulmonary congestion, and represents a key issue in the therapeutic approach to the syndrome.

Review and cost analysis of reverse osmosis and ultrafiltration [PDF]

, 2013
The aim in this study was to determine whether implementing an on farm ultrafiltration system was profitable. Ultrafiltration was researched to reduce the amount of milk hauled from producer to processor.

Characterization of Ultrafiltration Membranes [PDF]

Polymer Journal, 1991
Transport phenomena, that are relevant to ultrafiltration membranes, are discussed. Their basic characteristics are given by the pore-flow theory. In actual applications, however, their behaviors are controlled by gel layer formation, osmotic pressure of solutes, adsorption or plugging in pores and by other chemical and physical natures of membranes ...

An innovative strategy coupling cluster fraction with ultrafiltration UPLC-QTOF-MS/MS for screening α-glucosidase inhibitors from barley seedlings

Food Chemistry: X
Affinity ultrafiltration is widely used for rapid, targeted screening of bioactive natural compounds, but high-abundance components in complex matrices often mask low-abundance yet potent inhibitors, reducing sensitivity.

Ultrafiltration of water-based stains [PDF]

, 1994
V članku je opisana možnost čiščenja odpadnih vod, ki nastanejo pri luženju lesa z vodnimi lužili in sicer z ultrafiltracijo. Ultrafiltrirali smo simulirano odpadno vodo vodnega lužila in proučevali kvaliteto retentata in permeata.The article describes ...

Ultrafiltration behavior of polyelectrolyte and protein mixtures

, 1994
A number of nonchromatographic separation techniques have been developed previously in which polyelectrolytes are used as separating agents to reduce the cost or enhance the selectivity of protein purification techniques. This work examines the potential

In vitro evaluation of critical ultrafiltration fluxes and transmembrane pressure in a high flux dialyzer

Scientific Reports
In patients treated with haemodiafiltration, high convection volumes are considered beneficial. However it leads to pressure instability and membrane fouling.
