Wastewater Treatment Aeration Blowers

At industrial and municipal wastewater treatment plants, aeration blowers are a critical component of the treatment process.  Aerobic biodegradation is the natural process where bacteria use oxygen to break down organic materials in the sewage.  Providing oxygen to these organisms stimulates their activity and growth, so aeration blowers are used to increase the oxygen content in the wastewater.

This project featured clamshell style, hinged aluminum enclosures that protect the equipment while still offering easy access for authorized personnel at the wastewater treatment plant. At pdblowers we offer a variety of enclosure styles whether you are looking to protect your equipment from the elements or reduce its noise output. The examples below show some of our most popular enclosure styles, but we can custom build any type of enclosure to meet your specific application needs.
