Ring Sparger

Saifilter Ring Sparger is a device that introduces gases into liquids, commonly used in bioreactors and other fluid processing applications. As a leading Porous Sparger, it stands out in its ability to achieve efficient gas-to-liquid interactions. It's designed in the shape of a ring and contains numerous tiny holes or pores.

As gas is forced through these holes, it gets dispersed into the liquid in the form of fine bubbles. This design ensures even and efficient gas distribution, facilitating optimal oxygen transfer rates and ensuring uniform mixing in the fluid medium. Ring Spargers are often made of materials like stainless steel or sintered metals to endure rigorous operating conditions and maintain sterility in critical applications.

  • Energy Efficient: Due to their efficient gas-to-liquid transfer, ring spargers often lead to energy savings in operations.


  • Aeration: Air sparging to meet the Biological Oxygen Demand (BOD) in a waste stream.
  • Agitation: Air injection to mix liquids in a vessel.
  • Chlorine Bleaching: Chlorine sparging is used for bleaching pulp in the pulp and paper industry. 
  • Column Flotation: Air sparging is used in solid separation processes, such as coal flotation, where bubbles attach to solid particles, aiding their removal. 
  • Dewatering: Nitrogen sparging is used to remove entrapped water in engine oil. 
  • Fermentation: Oxygen or air sparging promotes cell growth during fermentation processes.
  • Gas/Liquid Reactions: Injecting air or oxygen into a reactor can enhance the performance of chemical reactions. 
  • Hydrogenation: Hydrogen sparging is used in various chemical hydrogenation reactions. 
  • Oil Flotation: Air or natural gas sparging is applied to separate oil from produced water in oil well operations. 
  • Oxygen Stripping: Nitrogen sparging can remove oxygen from substances like edible oils, wines, and juices, preventing oxidation. 
  • Oxygenation: Oxygen sparging significantly promotes fish growth in aquaculture. 
  • Ozonation: Ozone sparging is used for disinfection in ultrapure water systems in pharmaceutical factories. 
  • PH Control: CO2 or NH3 injection can regulate the pH of wastewater or process fluids. 
  • Steam Injection: Direct steam sparging achieves efficient heating and eliminates the "steam hammer."
  • Volatile Stripping: Air sparging removes volatile organic compounds (VOC) from waste liquids, contributing to environmental protection and pollution control.

A Ring Sparger is a device designed for introducing gases into liquids, commonly used in applications like bioreactors or fluid processing systems. It's shaped like a ring and is equipped with numerous tiny holes or pores. When gas is forced through these holes, it disperses into the liquid in the form of fine bubbles. This design ensures even and efficient distribution of the gas throughout the liquid, enhancing gas-to-liquid contact and transfer rates. Ring Spargers are often crafted from durable materials, such as stainless steel or sintered metals, to withstand demanding operating conditions.

A sparger's primary function is to introduce gases into liquids, ensuring efficient gas-to-liquid contact. This process results in the dispersion of the gas in the form of fine bubbles throughout the liquid medium, facilitating processes like aeration, oxygenation, carbonation, or other gas-related reactions in various industrial applications.

The design and construction of Ring Spargers reduce the chances of clogging. However, selecting the appropriate pore size and regular cleaning can further mitigate clogging risks.

The design of the Ring Sparger ensures the production of fine, consistent bubbles, which is crucial for efficient gas-liquid contact and mass transfer.
