The SBR wastewater treatment technology, which comprises approximately 80% of all small wastewater treatment plants installed is the most commonly used wastewater treatment method today.

The Klärmax® AirPro small wastewater plant is based on the SBR (sequential batch reactor) technology. Hereby the sludge is enriched with oxygen to set in motion a biological process. The plant features a pre-treatment coarse catch tank which also serves as buffer tank. The plate diffuser, sludge- and clearwater disposal are driven by an air pressure system.

Depending on the number of people connected, such a plant can comprise one or more tanks

There are no moving parts within the tank. Breakdowns inside the tanks are thus reduced to a minimum. The plant control is installed outside the tank and easily accessible at all times.
