Vortex Powered Aeration
The Problem
Aeration currently accounts for between 50% and 75% of a wastewater treatment plants energy use. This equates to 1.5% – 2.25% (average 1.9%) of a developed country’s electricity equating to about 279 TWh requiring approximately 24 million tonnes of oil equivalent (toe) annually. This typically is due to poor oxygen transfer performance and control.
Beyond energy inefficiency, existing aeration technologies also suffer a range of pain points such as:
- KSignificant equipment and infrastructure requirements
- KSignificant time for installation
- KPoor retrofitability
- KPrecarious maintainability requirements
- KComplex control protocols
- KNoise pollution


The Solution
This simple but innovative solution provides the following benefits:
- LLow total cost of ownership
- LUp to 50-year lifespan of equipment with pump replacement every 20 years
- LRetrofit in days instead months
- LAll access at the top of tank for maintenance in minutes
- LEfficient fully automated control
- LLower noise (20dB less than diffused)
The Solution
This simple but innovative solution provides the following benefits:
- LLow total cost of ownership (pay back in 3 to 5 years)
- LUp to 50-year lifespan of equipment with pump replacement every 20 years
- LRetrofit in days instead months
- LAll access at the top of tank for maintenance in minutes
- LEfficient fully automated control
- LLower noise (20dB less than diffused)

How It Works
The air and water mixture is then jetted back into the tank where it powerfully mixes the contents of the tank, both vertically and horizontally.
During this recirculation process, up to 30 % of the pumping energy is recovered through an innovative hydropower recovery module.
