What is Air Sparger?

An air sparger, sometimes also called a gas sparger, refers to an industrial device used to distribute gas needed for the reaction into a target liquid ( water, beverage, or chemical solvent ). Due to its particular function, air sparger can also use as a bubbler, carbonation tool, or diffuser.

Basically, air sparger is sintered of various materials including but not limited to stainless steel 304, 316L SS, 430 SS, titanium, Inconel, Monel, Nickel, and Hastelloy. With special sintering technology, the air sparger is featured with uniform pore distribution, a precise micron rating, and good mechanical strength to satisfy your different application needs.

Is There Any Difference Between Air Sparger and Steam Sparger?

Sure, there is.

You may think air sparger, steam sparger, and gas sparger have the same definition for they are in the same form. However, there surely is a difference between them.

The air sparger sometimes equals the gas sparger, but in some special conditions, the air sparger exactly refers to a sintered metal sparger to introduce ‘air’ to the reactor.

As for the steam sparger, it is mostly used to heat the liquid instead of simply introducing steam into the water and bringing reactions. We usually classify the steam sparger as air sparger or gas sparger.

What Types of Gas Can I Apply to An Air Sparger?

Determined by different industrial applications, there is a wide range of gas that can be applied to an air sparger including nitrogen, carbon dioxide, oxygen, ammonia, argon, chlorine, hydrogen, and ozone.

Next, I will list the main applications of these gases:

  • Nitrogen: to reduce the oxygen involved in edible oil, wine, fruit juice, and other beverages
  • Carbon dioxide: to control pH and carbonated beverages
  • Oxygen: to improve performance of reactor and provide a necessity for cells and biologies
  • Ammonia: to adjust pH in waste or process streams
  • Argon: to avoid oxidizing reactions during beer brewing
  • Chlorine: to bleach in pulp and paper industry
  • Hydrogen: to support chemical hydrogenation reactions
  • Ozone: to sanitize ultrapure water systems in pharmaceutical plants

If your application is not mentioned above, don’t worry. They are only some of the most common gases and applications. You can know more details by consulting our Filson professional engineering team.

What is the Need of Air Sparger in Bioreactor?

Oxygen is the most widely distributed element in nature. It is a necessity for almost all creatures existing on the earth. Oxygen is a colorless and odorless gas and it’s hard to be dissolved in water. Here it brings a challenge for cells in bioreactors.

At this time, an air sparger or oxygen sparger can help a lot. The sintered structure offers a precise and even more distribution on the surface of the device. The pores create thousands of paths for oxygen to pass through. Then the oxygen is introduced into the bioreactor in the form of millions of fine bubbles.

Though oxygen is not easy to dissolve in water, the small size bubbles increase the contact area between the gas and the liquid. By doing this, the cells in the bioreactor get enough oxygen for growth and productivity.

Is Air Sparger Expensive?

It depends…

It might not be that cheap for air sparger to be manufactured through a sintering process. It’s a high-end technology and a series of sintering equipment ( like the sintering furnace ) is really expensive to purchase. So there may be few factories in China to make this sintered metal-air sparger.

The price is greatly dependent on the construction material and manufacturing difficulty. For example, the food-grade SS 316L may be more expensive than other grades of stainless steel. And a multiple air sparger design may have a higher price compared to a single air sparger design.

However, Filson provides our customers quality air spargers at a competitive and reasonable price. That’s because we export the products directly from our factory which cuts a lot of your costs. Consult our specialists for an instant quote.

What Factors Should I Consider While Choosing an Air Sparger?

Choosing the right air sparger for your application helps realize the optimal sparging efficiency at a relatively low cost of production. And when selecting the air sparger, you are supposed to consider some factors below:

  • Your desired size of bubbles is determined by the pore size. So make sure that you give the right micron rating to the factory.
  • Pay attention to the properties of the gas and process liquid, eg: temperature and corrosion properties. The construction material must have the ability to tolerate the condition of your application.
  • Your air sparger has to withstand high mechanical shock and maximum process temperature and pressure of your system.
  • Be clear about the flow rate, contact time, gas exit velocity, and the actual ability of the air compressor. These will influence the performance of your air sparger.

By the way, an air sparger is able to last for several years, but it depends on the frequency of use and the material of construction. You are recommended to clean or replace your air sparger every four months for regular.
