Membrane Cascade-Based Separation
US Patent:
2005025, Nov 24, 2005
Filed:
May 20, 2005
Appl. No.:
11/134553
Inventors:
Edwin Lightfoot - Madison WI, US
International Classification:
B01D061/58
US Classification:
210641000, 210644000, 210321600, 210335000
Abstract:
The present invention provides counter flow cascade separation systems useful to separate solute/solute pairs present in a solvent. The separation systems include a series of interconnected stages with each stage comprising a combination of a diafilter preferentially permeable for one solute and an ultrafilter that accepts a permeate flow from the diafilter. The ultrafilter is permeable to solvent. Solute/solute pairs are preferentially separated by the diafilter into permeate and retentate flows and excess solvent is removed from the permeate flow by the ultrafilter and recycled back into the system. Stages are combined to form a counter flow cascade separation system capable of operation approaching an ideal counter flow cascade.

Hydrodynamic Method For Separation Of Solid Bodies Or Crystals
US Patent:
4010095, Mar 1, 1977
Filed:
Aug 1, 1974
Appl. No.:
5/493760
Inventors:
Joseph O. Hirschfelder - Madison WI
Edwin N. Lightfoot - Madison WI
David W. Howard - Aiken SC
Edwin N. Lightfoot - Madison WI
David W. Howard - Aiken SC
Assignee:
Wisconsin Alumni Research Foundation - Madison WI
International Classification:
B03B 500
US Classification:
209132
Abstract:
A method for hydrodynamic separation of enantiomorphic crystals such as mono-clinic or tri-clinic crystals as well as other bodies, at least one of which does not possess a center of hydrodynamic resistance, wherein said bodies are caused to move in one direction through a fluid in face contact with a supporting surface whereby lateral separation between crystals or bodies are effected in response to a resultant perpendicular force acting on said crystals or bodies.
