NRW - Contec Riverscreen
nrw contec riverscreens are an economical solution when it comes to the extraction of process water in the industrial or municipal sector.
The vertical screens, as they are also called, are constantly submerged in water. They are attached vertically, like a slide plate, to the outside of a sheet pile wall.
In the case of heavier soiling, a deflector grille is recommended to protect the screen from damage by larger objects such as pieces of wood, etc.
Numerous wastewater treatment plant operators and industrial companies trust the stable, durable contec screen for River water extraction.

Numerous wastewater treatment plant operators and industrial companies trust the stable, durable contec screen for River water extraction.
Particularly high separation efficiency of screenings in the form of floating, sinking, suspended and fibrous materials.
The riverwater screen scores thanks to its optimal ratio of screen area to size.
Thanks to its robust design, a nrw contec riverscreen rarely requires maintenance. Service lives of up to 20,000 operating hours are not uncommon.
We build the screen so that it fits you. In addition, you always receive the nrw contec screen ready for use. On-site assembly is usually not required.
A nrw contec riverscreen cleans reliably even if it has not been cleaned for a long period of time.
Only the adjustable brushes come into contact with the solids to be removed.
Depending on the application and design, nrw contec screens consume only between 0.45 and 5 watts per cubic metre of treated wastewater.
Easily adjustable brushes last up to several 10,000 hours of operation. No leakage due to worn seals between frame and rotating screens or screen drums.
- No discharge and disposal of screen necessary, as only clean water is taken from the river.
- Ideally suited as a retention system for carrier material of a biology.
- Encapsulated bearings in the underwater area.
- Flood-proof drives
A nrw contec riverscreen reliably removes floating matter such as wood or leaves. It also requires very little energy and is extremely low-maintenance.
- The solids to be filtered out are retained by the perforated screen and swept back into the flow by the slowly rotating brushes.
- Meanwhile, the cleaned water flows through the screen into the inlet structure. From there it usually flows into a further stage of water treatment.
- High degree of separation of screenings
- Low space requirement
- Extremely low maintenance
- Designed for high durability
- Economical thanks to low drive power
- Low-wear
- Retention of carrier material
- Withdrawal of river water
