Small wastewater treatment plants
The term fully biologicalsmall wastewater treatment plants defines plants for the cleaning of domestic wastewater up to an amount of wastewater of 8 m³/d.Fully biological small wastewater treatment plants are used, where the treatment in a central wastewater treatment plant is not possible.

The advantages of our fully biological small wastewater treatment plants
Durability and low operating costs
No electrics in the waste water
We think that power and water do not get along with each other so well. That is why we installed all live parts outside the tank in the control cabinet.
No mechanics in the waste water
We do not have a lot of mechanics, however, the mechanics we have is very robust. That is why we use with all our small wastewater treatment plants only linear piston compressors with five years of warranty. Out of conviction. It could not be any better!
No electric pumps in the waste water
We swear in wear-free, compressed air driven lifter without electric pumps. What is supposed to break? Our compressed air driven lifters survive definitely every electrical pump!
Functioning of our small wastewater treatment plants
Our fully biological small wastewater treatment plants are based on the proven SBR process (Sequencing Batch Reactor).
In contrast to other methods where three cleaning stages are necessary, with this procedure two are sufficient. The mechanical preliminary cleaning takes place in phase one, the biological cleaning as well as the secondary cleaning take place combined in one chamber.
Thus, a separate secondary cleaning tank is not necessary .
1. Charging phase
In computer-controlled intervals, the wastewater gets from the primary treatment tank into the SBR reactor.
2. Treatment phase
3. Sedimentation Phase
4. Clearwater removal phase
Frequently asked questions about small wastewater treatment plants
What are fully biological small wastewater treatment plants?
What is the difference between partially biological and fully biological small wastewater treatment plants?
Partly biological is the partly removal of unsolved pollutants, e.g. conventional sceptic tanks reach by means of mechanical removal (settling) a cleaning performance of approx. 30 %. Multi chamber tanks do not longer comply with the state-of-the-art and have to be retrofitted with a fully biological kit. Fully biological goes beyond that and removes by means of microorganisms even most of the solved pollutants. The cleaning performance regarding carbon degradation should not be below 90 %.
Why fully biological small wastewater treatment plants?
Fully biological small wastewater treatment plants are used, where the treatment in a central wastewater treatment plant is not possible. They reach the same cleaning performance as central wastewater treatment plants.
Which filtration levels are there?
The performance capability of small wastewater treatment plants is divided in five different filtration levels that among other things require different maintenance frequencies. Most commonly is the standard requirement, filtration level C, thus carbon degradation. Only in certain cases, e.g. in drinking water protection zones, a higher filtration level is required. The responsible authority has more information about that.
We have the following classification:
- C (carbon degradation)
- N (nitrification)
- D (denitrification)
- +P (phosphate elimination)
- +H (hygienization)
What happens to the cleaned wastewater?
After the treatment, the cleaned wastewater has to be returned to its natural water cycle. If possible, this should happen by means of adequate running waters. If there is no suitable receiving water, it can be percolated in the underground.
