Pure water is the foundation of a clean environment.
And nature is the model for using biofilms to achieve
ecological wastewater treatment.

Discover EvU-Pearl® – the high-performance
carrier material for biofilms.

With its special form and surface,
EvU-Pearl® provides an ideal growth area for a strong biofilm.

Microorganisms fasten themselves to the carrier surface and significantly reduce contaminants and pollutants in the wastewater.

On the outside area a weaker biofilm forms itself, with microorganisms working primarily in an aerobic way.

Inside, in the protected area, a relatively strong biofilm forms, working primarily in an aerobic and anoxic way.

The structure and the material establish an especially stable form, helping to prevent carrier material from clogging the necessary drainage sieves in the water treatment facility.

The anti-clogging and flow-through geometry
facilitates particular ease of access to the biofilm
on the carrier material, offering the extremely
high cleaning performance.

EvU-Pearl® works efficiently
even in surroundings rich in
suspended matter, ensuring the highest
in effectiveness in compact water treatment systems.

For the construction of your facility this means flexible possibilities for use:

EvU-Pearl® is flexible in use and functions
as a carrier material for growth as well as a filter and fill material in environmental engineering facilities. But beyond that …

  • For the decomposition of organic contamination (carbon decomposition) and inorganic pollutant particles (nitrogen decomposition through denitrification, Bio-P, acidification)
  • Brought into motion by agitators
  • For the decomposition of organic contamination (carbon decomposition) and inorganic pollutant particles (ammonium degradation through nitrification as sub-step in nitrogen removal)
  • Brought into motion by compressed air
  • Aquaristics The material is installed in prefabricated filters. There, it cleans the water that is fed through the circulation system.
  • Coalescence separators When integrated in the separator, the material accumulates oil content in the water.
Just in case: EvU-Pearl® is convincing for five good reasons
  1. Ecological – EvU-Pearl® is modelled on nature
  2. Efficient – The simple geometric composition and finely toothed structure establish a high-potential growth surface
  3. Reliable – An optimal and strong biofilm is created
  4. Resistant – Because of the lasting flow-through form there is low susceptibility to clogging
  5. Flexible use – Aerobic or anoxic processes can be promoted by adapting the geometry
