Crossflow filtration for CHO cell separation by microfiltration using crossflow systems.
Chinese Hamster Ovary (CHO) cells are used for fermentation of high value proteins in the pharmaceutical- and biotechnology industry. During the fermentation process the cells are grown under specific conditions in a defined media. The CHO cells produce extra cellular proteins. Separation and purification of these proteins result in the final product of high value. The production steps utilized...
متن کاملSinusoidal crossflow microfiltration device--experimental and computational flowfield analysis.
We present an analysis of the flowfield inside a novel crossflow microfiltration device. The filter performance relies on shear focusing by means of a corrugated channel. The flow and shear stress characteristics inside the filter are studied by means of both micro Particle Image Velocimetry (micro-PIV) measurements and Computational Fluid Dynamics (CFD) analysis. We show that an increase of th...
متن کاملApplication of Cross-Flow Electro-Microfiltration in Chromium Wastewater Treatment
Cross-flow microfiltration (CFMF) was experimentaLLy studied for the separation of precipitates of chromium hydroxide. Although this process enables one to obtain chromium-free filtrate, a disadvantage is that the filtration flux declines rapidly due to membrane fouling. In order to avoid this fouling problem and increase the filtration flux, an electric field was applied across the membrane as...
متن کاملCrossflow microfiltration of recombinant Escherichia coli lysates after high pressure homogenization.
Crossflow membrane filtration was used to process recombinant Escherichia coli cell lysates containing protein inclusion bodies after high pressure homogenization. The number of passes through the high pressure homogenizer changed the viscosities and average particle sizes of the cell lysates. The different cell lysates were processed with a hollow fiber unit containing microfiltration membrane...
متن کاملUnderstanding Direct Flow and Crossflow Microfiltration in Food and Beverage Industry Applications
Direct flow (sometimes called “dead end”) filtration is applied when all the fluid to be filtered is driven, typically in industrial applications due to a supply pressure, in a direction perpendicular to a filtering surface; few applications are done by gravity feed. Contaminants are captured within the filtration media or build up on the surface, causing the differential pressure across the fi...
