Micro Spargers for Bioreactors

Micro spargers from Mott are engineered to significantly reduce bubble size and increase gas transfer and volumetric mass transfer coefficient (kLa), resulting in reduced gas consumption and improved upstream reactor yields. These micro spargers can increase mass transfer rates by 100% to 400% over standard drilled pipe or single-opening dip tubes, making them highly efficient for bioreactor and fermentation processes. By producing extremely fine bubbles, micro spargers enhance the gas-to-liquid contact area, facilitating a more efficient gas dissolution into the liquid phase. This efficiency is crucial in applications such as pharmaceuticals, biotechnology, and wastewater treatment, where precise control over gas transfer is essential for process optimization and yield improvement.

FAQs: Micro Spargers

Q: What are Micro Spargers?

A: Micro Spargers are precision-engineered devices designed to disperse gas into liquids through a porous metal element, creating extremely fine bubbles. This results in a significantly increased gas-to-liquid contact area, enhancing the efficiency of gas transfer processes in various applications, such as bioreactors, fermentation tanks, and environmental water treatment.

Q: How do Micro Spargers improve process efficiency?

A: Micro Spargers improve process efficiency by producing finer bubbles than traditional sparging methods, which increases the surface area for gas exchange and enhances the dissolution of gases into liquids. This leads to improved mass transfer rates, reduced gas consumption, and higher yields in processes such as fermentation, oxygenation, and aeration.

Q: Can Micro Spargers be used with any type of gas?

A: Yes, Micro Spargers are versatile and can be used with a wide range of gases, including oxygen, carbon dioxide, nitrogen, and air. Their design allows for efficient gas dispersion regardless of the gas type, making them suitable for diverse applications across pharmaceutical, biotechnological, and environmental industries.

Q: Are Micro Spargers customizable to specific process requirements?

A: Absolutely, Micro Spargers can be customized to meet specific process requirements, including the size, shape, and porosity of the sparger, as well as the material to ensure compatibility with different gases and liquids. Mott works closely with clients to design Micro Spargers that fit their exact needs, optimizing performance and efficiency.
