Static Screen for Solid/Liquid Separation

The
Hydrasieve® is a highly efficient screen, designed for solid/liquid separation.
The simple design and robust construction of the Hydrasieve give trouble-free operation. Frames and screen plates are made in stainless steel.

Additional options are available in order to improve the operation of the screen: rotating or motorised spray system or protective cover.

The Hydrasieve® is a simple, highly efficient screen, designed for solid/liquid separation. Thousands of worldwide installations on all types of applications prove its efficiency. Its operation is based on the Coanda effect. This means that the liquid to be screened forms a hydraulic attachment to the bars of the screen plate. These bars, with triangular section, have rounded angles and have a wave configuration, as opposed to being straight. Thus, the liquid passes through the slots while the separated solids stay on the front face of the screen plate.

Principle of Operation

The screen plate has three distinct angles. This arrangement ensures:

  • elimination of the majority of the liquid
  • deceleration of the screenings
  • drainage

The screen plate is supported by a frame which initially ensures quietness and even distribution of the effluent on the whole width of the unit and then accelerates the liquid down the screen plate. The filtered liquid is then collected in the screen base.The screen plate and the frame constitute the Hydrasieve®.

The simple design and robust construction of the Hydrasieve® give trouble-free operation with the following advantages:

  • No moving parts, no motor
  • Very low installation costs; no maintenance
  • Only requires periodic cleaning
  • Quiet operation

Wave shape of the bars give the Hydrasieve® its self-cleaning effect.
