Latest Patents
Lightfoot's latest patents include advancements in membrane cascade-based separation systems. The first patent presents counter flow cascade separation systems designed to separate solute/solute pairs present in a solvent. This invention features a series of interconnected stages, each equipped with a diafilter that is preferentially permeable for one solute. The system effectively separates solute/solute pairs into permeate and retentate flows, approaching an ideal cascade operation.
The second patent also revolves around membrane cascade-based separation. It introduces a counter flow cascade separation system that combines a diafilter and an ultrafilter. The diafilter preferentially separates solute/solute pairs, while the ultrafilter removes excess solvent from the permeate flow and recycles it back into the system. This innovative approach enhances the efficiency of the separation process.
