Why Micro Bubble Air Stone for Bioreactor ?
More and more Sintered Metal micro-bubble air stone is commonly used in bioreactors for several important reasons
you may interested to know :
1. Oxygen Transfer Efficiency:
Bioreactors are vessels where biological processes take place, such as cell culture, fermentation, or wastewater treatment. In these processes, microorganisms or cells require oxygen to grow and metabolize. Micro-bubble air stones are designed to create very small bubbles, which increases the surface area of the gas-liquid interface, leading to highly efficient oxygen transfer into the liquid. This promotes the growth and productivity of the biological organisms within the bioreactor.
2. Uniform Dissolved Oxygen Distribution:
Micro-bubbles disperse more evenly throughout the liquid in the bioreactor compared to larger bubbles. This uniform distribution of dissolved oxygen helps maintain consistent conditions throughout the bioreactor, reducing the risk of localized oxygen depletion, which can harm cell growth and lead to uneven results.
3. Reduced Shear Stress:
When using mechanical agitation or larger bubble aeration, there can be higher shear stress on the cells or microorganisms, potentially damaging them. Micro-bubble air stones provide a gentler and more controlled aeration process, minimizing the risk of cell damage and ensuring the viability of the biological culture.
4. Enhanced Mass Transfer:
Apart from oxygen, bioreactors may require the addition of other gases or nutrients to support the biological processes. Micro-bubble air stones can be used not only for oxygenation but also for efficient mass transfer of other gases and nutrients, improving the overall performance of the bioreactor.
5. Improved Mixing:
Micro-bubbles created by the air stones contribute to mixing within the bioreactor, ensuring homogeneous distribution of cells or microorganisms and maintaining a uniform environment, which is crucial for consistent product quality in large-scale bioprocessing.
6. Contamination Prevention:
The use of micro-bubble air stones can help reduce the risk of contamination. Since the air supplied to the bioreactor is typically filtered, the introduction of clean, filtered air through micro-bubbles helps maintain a sterile environment, preventing the entry of contaminants that could negatively impact the biological culture.
In summary, the adoption of micro-bubble air stones in bioreactors offers significant advantages, including improved oxygen transfer efficiency, uniform dissolved oxygen distribution, reduced shear stress on cells, enhanced mass transfer, better mixing, and a lower risk of contamination. These factors collectively contribute to the success and productivity of the bioprocesses occurring within the bioreactor.
