Why is aeration needed in water treatment and water basins?
- Aeration brings oxygen into the water and keeps the water moving
- This keeps the bacteria that clean the water alive
- Standing water without oxygen starts to smell and produces algae, such as blue-green algae
Roots blowers, side channel blowers and turboblowers are used for this.

- Aeration brings oxygen into the water and keeps the water moving
- This keeps the bacteria that clean the water alive
- Standing water without oxygen starts to smell and produces algae, such as blue-green algae
Roots blowers, side channel blowers and turboblowers are used for this.
"
- Which technique suits which aeration application?
"
| Situation | Characteristic | Suitable technique |
|---|
| Shallow basins, low counterpressure | High flow, little pressure | Side channel blower |
| Deeper tanks, constant counterpressure | Higher pressure build-up | Roots blower |
| Continuous duty, high air volume | Energy consumption dominates | Turboblower, for example Master Blower |
"
- Why does energy consumption weigh so heavily in aeration?
"
- Aeration blowers often run 24 hours a day and therefore account for a large share of the installation's energy use
- In continuous duty a power reduction of a few kW quickly adds up to thousands of euros a year
- Frequency control and IE3 or IE4 motors make it possible to follow the actual air demand
"
- What data is needed to select an aeration blower?
"
- required air flow in m³/h
- water depth or injection depth, and therefore the counterpressure
- length and diameter of the pipe to the blower
- continuous or cyclic duty
- installation: indoors or outdoors, noise requirements and dust in the surroundings
Waste processing uses the same technology: a directed air flow or aeration by blowers.
