Physico-mathematical modeling of crossflow filtration

Computational Fluid Dynamics of Crossflow Filtration in Suspension-Feeding Fishes Keywords: Crossflow filtration, Suspension feeding

Suspension-feeding fishes such as herring and anchovies engulf particle-concentrated water through their mouths and release the water through the posterior oral cavity. Food particles are separated from the water at the gill rakers that act like modern crossflow filters. This paper uses Computational Fluid Dynamic (CFD) techniques to study the feeding mechanism of these suspension feeders. By u...

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...

Vapor-Particle Separation Using Microporous Metallic Membrane in Crossflow Filtration

Simultaneous separation of vapor and particles in industrial processes could be a key step toward manufacturing of high-quality goods. The separation is critical for successful measurement of volatile or semi-volatile aerosol particles, which no reliable technique exists. We have developed a technique for separation of vapor and particles simultaneously using a specialty microporous metallic me...

Crossflow Filtration of Sodium Chloride Solution by A Polymeric Nanofilter: Minimization of Concentration Polarization by a Novel Backpulsing Method

In the present study, the production of low-salt water from salty water by nanofiltration as well as membrane fouling was investigated. Furthermore, a new method was proposed and tested experimentally for creating the backpulse in order to minimization of fouling and increase of the filtration efficiency. In the proposed method, the permeate was used instead of gas for creating the...
