The Coanda Screen represents a pinnacle of advanced fluid dynamics in water intake filtration. Specifically engineered for hydroelectric power plants and industrial water treatment, this high-efficiency screen utilizes the Coanda effect—where the flow of water adheres to a curved surface—to accurately separate debris from the stream. By leveraging exerted flow forces, it ensures a continuous, high-quality water intake while eliminating the need for complex mechanical filtration systems.
Designed for durability and sustainability, our Coanda screens are manufactured from premium-grade stainless steel to withstand the harshest environmental conditions. Whether applied in municipal water supply or marine coastal projects, these screens offer a seamless integration of high-flow wedge wire technology and an environmentally conscious design that protects aquatic life and fish stocks, making it the ideal choice for modern green infrastructure.

Frequently Asked Questions
It uses the Coanda effect to separate debris, stones, and leaves from the water stream, allowing clean water to pass through while flushing waste away automatically.
The screen is designed with a specific tilt angle and curved profile that utilizes the natural force of the water flow to shear debris off the surface and carry it downstream.
For marine and coastal environments, Stainless Steel 316 or 316L is highly recommended due to its superior resistance to chlorides and saltwater corrosion.
Yes, we offer customizable apertures ranging from 0.1mm to 2.0mm to ensure the screen captures the specific size of contaminants relevant to your site.
The unique hydraulic profile prevents fish from being impinged or trapped against the screen, allowing them to bypass the intake safely.
Absolutely. Coanda screens are widely used in hydro projects to protect turbines from debris while minimizing the need for expensive mechanical rake systems.
