What Is A Coanda Screen?
The Coanda screen is a form of water intake that is self-cleaning and static, requiring no electricity and little maintenance.
Also, the Coanda screen employs a wedge-wire screen constructed in the form of an vee-shaped slope.
Furthermore, the ogee slope above the screen is determined by a solid acceleration plate.
The slope generates the high sweeping velocities required for self-cleaning.
Flat wedge-wire is the most basic sort of Coanda screen encompassing wedge-shaped wires welded to backer rods below the screen.
The close spacing of the wires allows fluid to pass through while preventing passage of solids.
Coanda screens will reliably operate depending on the slot opening.
Why Should You Employ Coanda Screens?
You find the following pros in employing Coanda screens:
Self-cleaning features result in a mostly maintenance-free operation, reducing time and associated expenses.
Reliable supply of screened water increases hydro plant running time, production, and efficiency.
You can adjust slot gap sizes to screen trash with diameters ranging from 0.2mm to 2mm.
Because there are no mechanical moving parts, there is no need for costly maintenance or a power source.
Highly durable screen construction resists abrasive material and corrosion.
Coanda screens have proven operational effectiveness even at low temperatures without freezing in some of the world’s harshest regions.
In fisheries conservation areas, Coanda screens are trusted not to harm fish stocks.
