This is how the Drausy® system works:

It creates an aerobic environment at the bottom of the watercourse through gentle aeration: This is possible because the tiny nanobubbles settle at the bottom and in their surroundings, resulting in a high retention time of oxygen. 

Aerobic microbacteria are attracted, metabolise the organic matter and bind pollutants to the sediment. This results in an efficient oxygen supply: special Drausy® system hoses aerate the bottom of the watercourse with nano-bubbles pressure-equalising over long distances (several kilometres).

This is what you need for your Drausy® system:

A Drausy® Professional ventilation system requires energy for operation in order to generate compressed air from ambient air.

An oil-free compressor generates the required compressed air from ambient air - this is stored in a compressed air tank and continuously delivered to the ventilation system in finely dosed quantities.
