Aeration controls in wastewater


Howden’s history with centrifugal technology within the wastewater treatment segment dates back to the 1930’s. Through the years there have been numerous advancements in wastewater treatment technology not only in aeration equipment, but also in advanced process controls.

Using Howden's Roots® technology it is possible to reduce the major source of process inefficiency in wastewater plants, namely excess aeration.

Utilising Direct Flow Control with Most-Open-Valve logic can help lower the required system pressure which in turn will reduce power consumption of the aeration blowers.

Howden also specializes in designing and providing aeration Control systems that provide valuable process performance while maximizing energy efficiency. There is no plant too small or too big that we can’t help improve your control scheme while being conscious of short term payback to maximize energy savings that will justify the capital improvements.
