Coanda Screen

Coanda Screen

Coanda Screens (Coanda intake screen,Coanda screen system ) are water treatment Coanda screens, exploit the Coanda effect in combination with the proven separation technology of wedge wire, using the special curved wedge wire screen.

Coanda Screens is a self-cleaning screen with no moving parts that have been successfully used for debris and fish exclusion in a wide range of applications across the world including hydropower plant intakes, water conservation schemes, and irrigation programs. In addition, the shape of the Coanda screen helps ensure that the filtration process is accurately completed by the flow forces exerted.

Our team can advise and assist with：

• Screen selection and bespoke design
• Retrofit and replacement screen solutions
• Benefits of Coanda Screens
  • A reliable supply of screened water which increases hydro plant operating time, output and efficiency.
  • Self-cleaning properties result in a largely maintenance-free operation saving time and associated costs.
  • Slot gap sizes can be specified to screen debris.
  • No mechanical moving parts eliminates the need for costly maintenance and a power supply
  • Coanda screens modular construction ensures ease of assembly
  • Highly resilient screen construction is resistant to abrasive material and corrosion
  • Proven operational performance even at low temperatures
  • Trusted in fisheries conservation areas not to cause harm to fish stocks
  Application

  The main applications of the Coanda screen system are:

  1. Hydroelectric power plants

  Coanda screen prevents harmful materials, and deposits in the suction process and ensures clean water. In this way, turbine blades in hydroelectric power stations can run longer without being damaged.

  2. Agricultural Applications

  Coanda screen is preferred for agricultural applications, for example, to provide plants with clean water. Coanda Screen prevents sediment, sticks, and soil from the water channel. This provides significant solutions for agricultural applications where clean water is required. In agriculture, the Coanda screen system is also used for mobile filtration.

  3. Wastewater treatment

  Coanda filter screens can provide clean water for municipal applications such as wastewater treatment. Efficient filtration of liquid-liquid separation aids in zero-power wastewater treatment applications.

  4. Drinking water
  Because of its superior filtration and self-cleaning ability, the Coanda screen is widely used in the industry. The perfect filtering of the water ensures that it is safe for human consumption.
