Description

The Coanda sieb system, also called Coanda intake screen, provides filtration using the special curved wedge wire screen. Coanda screens are mainly used to filter water using the principle of the Coanda effect. In addition, the shape of the Coanda screen helps ensure that the filtration process is accurately completed by the flow forces exerted.

Coanda Sieb systems
HOW DOES IT WORK?
Due to the Coanda effect – liquid follows a surface – in combination with the shearing effect of the profile bars, the water flows into the intake and prevents the penetration of small aquatic creatures in the water system. 
Flowing media have the property of sticking to flat or convex surfaces according to the Coanda effect. Example of flowing water on a spoon: If you hold a spoon in a stream of water, the water follows its curved surface and leaves it in a different direction than it came. You can feel the associated force that pulls the spoon into the water jet. Our Coanda screens work on the same principle.


The main applications of the Coanda Sieb screen system are:
  • hydroelectric power plants
  • Agricultural Applications
  • drainage
  • drinking water
  • sediment filtering
  • water supply

Various grades of stainless steel are the most commonly used materials for the Coanda screen. In addition, we are able to manufacture with different materials and grades as required. Special surface treatments are also available for your panel frame wedge screen application.
