Membrane separation optimization for fermentation broth processing

Overview

Membrane separation optimization offers an advanced solution for processing fermentation broths, addressing the challenges of high viscosity and complex compositions. By integrating chemical separation with bioengineering, this technology enhances flux, reduces fouling, and improves product purity. The solution utilizes pretreatment methods such as pH and temperature adjustments, along with anti-fouling membranes and real-time monitoring, to ensure optimal performance. It features modular, standardized, automated systems using ceramic or high-temperature polymer membranes, allowing for 24-hour continuous operation, easy replacement, and broad tolerance to pH and solvents.

Technical specifications

Key features:

• Crossflow filtration: Utilizes controlled transmembrane pressure (TMP), flow, molecular weight cut-off (MWCO), temperature, and CIP cleaning for high efficiency.
• Membrane materials: Includes ceramic and high-temperature polymer options, resistant to fouling and suitable for harsh conditions.
• Operational efficiency: Reduces energy use to approximately 1/5 of thermal methods while maintaining stable yields.
• Modular design: Facilitates easy replacement and maintenance, extending membrane life and reducing labor.

Technology readiness level

The technology is currently at TRL 5, with future validation planned in five phases. Initial feasibility has been confirmed using real fermentation broth in pilot trials. Ongoing efforts focus on optimizing system parameters through pilot operations and detailed engineering design. Final stages aim for industrial readiness and long-term deployment with digital monitoring.
