Optimizing protein-cell separation in submerged membrane bioreactor for clarification

Abstract
En 中文
• Fractional factorial design (FFD) reveals complex multi-parameter fouling interactions. • Yeast concentration dominates flux decline through cake layer formation. • BSA exhibits dual functionality as both foulant and flux modifier. • Optimal backwashing (BW) achieves 20–25 % flux and BSA transmission gain. • Concentration-independent BSA transmission enables high-titer bioprocessing.
