Worm screens

Worm screens are used for municipal and industrial wastewater treatment plants, where it is used to capture and discharge of solid impurities from the feed wastewater.

They are installed directly into the concrete channel, or mounted in a custom metal sump. Sealing frame screens for concrete walls channel, or the metal walls of the pit are using plastic or rubber elements. The water is filtered through a sieve, which is made of stainless steel with different sized round holes. Impurities collected on a sieve are discharged by the screw.

The advantages of worm screens are mainly:

  • The frame screens are made of stainless steel
  • Simple design and robust auger ensure trouble-free operation and long life
  • Installation of screw screens directly into the channel eliminates the need for pumping waste water, thus reducing their operational costs
  • Operation of worm screens can be automated, the operation is controlled by the valve, which allows you to set the interval running or is controlled by level sensors
