Separation & Purification
Separation and purification technologies are specialized unit operations that isolate target molecules from complex mixtures. In alternative protein production, these technologies include membrane filtration (micro, ultra, nano), centrifugal separation, chromatographic methods, and precipitation techniques. They are essential for achieving food-grade purity levels.
Process Overview
- 1Pre-filtration: Remove large particles
- 2Primary Separation: Centrifugation or coarse filtration
- 3Fine Filtration: Membrane-based separation (UF/NF)
- 4Chromatography: High-purity isolation of target molecules
- 5Polishing: Final purification and buffer exchange
Key Equipment
- Membrane filtration systems (UF, MF, NF, RO)
- Disc stack centrifuges
- FPLC/HPLC chromatography systems
- Decanter centrifuges
