- Maximum possible energy efficiency through micro-perforation and large membrane surface area
- High degree of system efficiency through increased dwell time of oxygen owing to installation close to the floor
- High process reliability through low-wearing and clogging-free membrane and integrated non-return valve
- High operational reliability thanks to division into small aeration fields
- High flexibility in the plant control system through the air intake’s large control range
Aeration system consisting of strip diffuser and pipeline system to distribute compressed air. On-site downspout or air intake pipe can be connected directly to pipeline system.
For fine bubble aeration of various fluids such as wastewater and sewage or sludge, for the purpose of supplying oxygen and mixing.
Compressed air generators input air into the pipeline system via the air intake pipe. The pipeline system evenly distributes the supplied air to individual diffusers. Air is evenly input to the fluid free from coalescence via a sewage-resistant membrane.

The aeration system is composed of one or more aeration fields. An aeration field consists of several components.
The strip diffuser consists of a supporting strip with a strip membrane placed over it. The strip membrane is fastened to the supporting rail with two fixing caps.
An integrated non-return valve prevents fluid from entering the pipeline system when the membrane is relaxed. As a result of the membrane’s excellent resilience, its perforation remains sealed when the membrane is not loaded.
It is fixed close to the basin floor via a fastening plate made of plastic.
The energy-efficient pipeline system guarantees ideal air distribution with low levels of pressure loss. It is detachable, height-adjustable and adapted to the characteristics of the basin and other plant technology.
