Fine Bubble aeration is a process where small bubbles are injected into a water or wastewater treatment tank in order to increase the dissolved oxygen (DO) level. There are two main types of diffusers used for this process: disc diffusers and tube diffusers. Both have their own advantages and disadvantages that should be considered when choosing which one is right for your treatment system. In this blog post, we will compare the two types of diffusers and discuss the pros and cons of each. After reading this, you should have a better understanding of which type of diffuser is best suited for your needs.

The difference between the two

When it comes to aeration, there are two main types of diffusers: fine bubble aeration and coarse bubble aeration. Both have their own benefits and drawbacks, so it’s important to know the difference between the two before choosing a diffuser for your application.

Fine bubble aeration is ideal for applications where dissolved oxygen (DO) levels need to be increased. This type of diffuser produces small bubbles that quickly dissolve in water, providing a large surface area for oxygen to be absorbed. Fine bubble aeration is also much quieter than coarse bubble aeration and doesn’t produce as much turbulence in the water.

The main drawback of fine bubble aeration is that it is less efficient than coarse bubble aeration when it comes to transferring oxygen into the water. This is because the small bubbles produced by fine bubble diffusers have a tendency to rise to the surface of the water instead of staying suspended in the liquid.

Coarse bubble aeration is best suited for applications where DO levels don’t need to be increased, but rather maintained. Coarse bubble diffusers produce larger bubbles that don’t dissolve as quickly in water. These larger bubbles provide less surface area for oxygen transfer, but they are more efficient at keeping oxygen suspended in the liquid and preventing it from rising to the surface.

The main drawback of coarse bubble aeration is that it can create more turbulence in the water, which can lead to sediment being stirred up

similarities between the two

There are many similarities between the two types of diffusers, including the fact that they both use bubbles to aerate the water. Both diffusers also have an inner and outer tube, with the inner tube having holes that release the bubbles. The main difference between the two lies in the shape of the bubbles. Fine bubble aeration DISC diffusers create round bubbles, while fine bubble aeration tube diffusers create long, thin tubes of bubbles.

Ming Ye Machinery can manufacture both

Ming Ye Machinery is a trusted name in the aeration industry, and we are proud to offer both DISC and Tube diffusers to our customers. Both types of diffusers have their own advantages and disadvantages, so it's important to choose the right one for your needs.

DISC diffusers are more efficient than tube diffusers, but they are also more expensive. They are less likely to become clogged, and they provide a more uniform distribution of bubbles. However, they are not as effective in shallow water applications.
