The ClearFox nature doesn’t only handle the sewage which occurs in single-family houses or multi-family houses with normal usage, it can also be used in situations where the wastewater volume varies.

The restriction valve against overload or underload makes the clearfox nature rather impervious – the feeding  of the bioreactor happens hydraulically completely constant

Maintenance of a ClearFox nature sewage treatment plant

This picture was made during maintence where samples were taken and the functionality of the plant was tested
the sewage treatment plant without power supply needs maintenance once a year in order to prove the effluent quality by external laboraties.


What are the advantages for clearfox nature customers?

  1. The biomaterial is forever, no need for any exchange like other “filters”, can be recycled, as it is fully made of plastic
  2. Constantly cheap operation since it doesn’t need power, if there is enough gravity
  3. The ClearFox nature almost disappears odour and soundless within the smallest area.
  4. No heavy lifting device is needed, due to the pit-tested polyethylene container with stainless steel reinforcement inside, totally weight less than 170kg.


Mit Hilfe unserer eines Mini Baggers Zulaufdrossel welche auch größere Abwassermengen (Überlast) ab puffert wird die Biologie gleichmäßig beschickt

The biology is evenly distributed with the help of our inlet throttle that can also buffer larger wastewater volumes (overload situtuation).

Nicht verrottendes Biofilm Aufwuchsträgermaterial welches nicht ausgewechselt werden muss. Selbst nach einer Ruhezeit von bis zu 6 Monaten (Unterlast) werden die Ablaufwerte der Anlage nach einer kurzen Einlaufphase wieder erreicht

Non-rotting biofilm material made in Polyethlen , that does not have to be exchange anytime.

Even after a resting period of up until 6 months (underload), the plant will reach its discharge values again after a short start-up phase.
