Title:
MODEL FOR MICROFILTRATION OF POLY-DISPERSE SUSPENSIONS
Document Type and Number:
WIPO Patent Application WO2004016334
Kind Code:
A3
Abstract:
The present invention relates to a method for predicting pressure independent permeation flux and target molecule yield in a permeate resulting from crossflow filtration of particles in a poly-disperse suspension, a method for determining packing density of particles at the membrane wall of a poly-disperse suspension, a method for designing a filtration system for a poly-disperse suspension, a method of selecting operating conditions of a crossflow filtration system for poly-disperse suspensions, and a method of modeling a process for filtration of a poly-disperse suspension using a computer generated program for predicting pressure independent permeation flux and target molecule yield.
