Fine Bubble Air Diffuser Product Description：
In the primary and secondary treatment of wastewater, it is common to use aeration as a method of removing organic matter. Submerged bubble aeration, in particular, works effectively by diffusing small air bubbles to mix with the wastewater and facilitating the work of aerobic bacteria in breaking down organic waste. Generally, submerged bubble aeration provides a more advanced system than surface aeration, and many wastewater treatment facilities have moved in this direction. Disk diffusers consist of an EPDM rubber membrane mounted onto a plate.Juntai offers a unique PTFE coating on the rubber membrane that is highly effective at combating bacterial coating and fouling. As compressed air flows through the membrane, the rubber expands. This expansion opens the constellation of small holes and releases thousands of bubbles into the water. Though Fine Bubble Air Diffuser and tube diffusers make up two primary types of fine bubble diffusers, other types of fine bubble diffusers are available too, such as perforated tubing, or bubble tubing, Fine Bubble Air Diffuser. These consist of perforated plastic panels. Compressed air flows through and leaks out through the perforations. Standard Aeration Efficiency (SAE) is measured by the number of pounds of oxygen mixed into the wastewater per horsepower hour as produced by the blowers that power the treatment system. Fine bubble diffusers disperse more oxygen into the water column for more efficient aeration, typically producing at least twice as much oxygen mass as comparable coarse bubble diffusers. Especially during secondary treatment, when wastewater must be purified to meet the EPA standard of removing 85% of organic matter, efficient aeration is a strong asset.
Some of the disadvantages of Fine Bubble Air Diffusers include the following:
Higher maintenance needs: Tube diffusers typically require higher levels of maintenance than disc diffusers, though using membranes with a protective coating like PTFE can help reduce maintenance requirements.
Shorter lifespans: Tube diffusers tend not to last as long as disc diffusers, though using membranes with a protective coating can help tube diffusers last longer, as well.

Higher likelihood of catastrophic failure: Because tube diffusers have larger orifices than disc diffusers, the likelihood of catastrophic failure increases. If an orifice cracks, the large opening could leak enormous amounts of oxygen. However, the use of fine-bubble tube diffusers can help decrease this risk.
