Algae Sparger

Saifilter Algae Sparger is a device specifically designed to introduce gases, typically air, oxygen, or carbon dioxide, into algae cultivation systems or photobioreactors. Leveraging the efficiency of a Porous Sparger can further improve gas introduction and distribution. The introduction of these gases is crucial for supporting photosynthesis, growth, and metabolic activities of the algae.

The sparger creates a consistent stream of fine bubbles, ensuring the algae receives uniform gas distribution. This facilitates efficient gas exchange, optimizes nutrient uptake, and helps in removing any unwanted gases from the system. Utilizing an appropriate sparging method can enhance algae biomass yield and ensure a healthy cultivation environment.

Stainless steel diffusion sparger stone for Microalgae Cultivation

A Stainless Steel Diffusion Sparger Stone is a specialized device for introducing gases into microalgae cultivation systems. Made from stainless steel, this sparger stone features a multitude of fine pores, allowing gases like carbon dioxide (CO₂) or air to be diffused into the cultivation medium in the form of tiny, consistent bubbles. The fine bubbles ensure optimal gas-liquid contact, promoting efficient gas exchange, which is essential for the growth and metabolism of microalgae. 

The stainless steel construction ensures durability, resistance to corrosion, and ease of sterilization, making it ideal for controlled and sanitary cultivation environments. In the context of microalgae cultivation, such spargers play a crucial role in enhancing productivity by ensuring uniform distribution of essential gases throughout the culture medium.

  • Fine Bubble Production: The micro-diffuser generates consistently small bubbles, ensuring a higher surface area for optimal gas exchange, which is crucial for photosynthesis and growth in microalgae and cyanobacteria.
  • Gentle Agitation: Given the delicate nature of microalgae and cyanobacteria cells, the micro-diffuser provides gentle agitation, preventing cell damage and ensuring uniform distribution of nutrients.
  • Efficient Gas Transfer: Enhanced gas-liquid contact ensures efficient transfer of carbon dioxide (CO2) for photosynthesis and the removal of oxygen, optimizing the growth environment.
  • Scalability: Micro-diffusers can be adapted for various scales of cultivation, from research-scale bioreactors to large-scale commercial operations.
  • Reduced Energy Consumption: The design of the micro-diffuser ensures efficient gas diffusion with minimal energy input, making the cultivation process more sustainable and cost-effective.


  • Optimal Gas Exchange: Microalgae and cyanobacteria rely on photosynthesis, requiring carbon dioxide and light to produce energy. The micro-diffuser ensures efficient delivery of CO2 for this process.
  • Consistent Bubble Size: The micro-diffuser produces uniform, tiny bubbles, providing a stable environment for the microorganisms and ensuring they are not harmed by varying bubble sizes or intense agitation.
  • Gentle Circulation: The fine bubbles gently circulate the cultivation medium, ensuring the microorganisms have consistent access to nutrients and light without being subjected to harsh mixing forces.
  • Efficiency: By producing a large number of tiny bubbles, the micro-diffuser ensures a more efficient gas-to-liquid transfer rate, which can enhance the growth rate of the microalgae or cyanobacteria.
  • Scalability: Whether in a small lab setting or large-scale commercial production, micro-diffusers can be adapted to different scales, ensuring optimal growth conditions across various volumes.
