Coanda Intake Screen, also called Coanda Hydro Screen, provide self-cleaning with the special geometry based on the Coanda Effect phenomenon. The Coanda screen is capable to enable liquid-solid separation with high filtration performance. The hydro screen prevents the sediment, sticks, rock, and dirt with the small-sized openings with no-moving parts and no power requirement.

How Does It Technically Work?

The curved screen of the Coanda Screen consists of V-shaped wedge wires that are placed in exact locations that will create a Coanda effect for the filtration. These wedge wires have a specific gap and tilt angle relative to each other.

Water flows through this gap between the V-shaped wedge wires by preventing other particles. Thus, this gap and the tilt angle defines both capacity and filtration performance. Also, the curved shape of the Coanda screen helps the filtration process complete accurately by the exerted forces of flow. Unwanted particles such as sediment, rock and stick follow the curved shape with this exerted force. As a consequence, it provides self-cleaning.

In the design of the Coanda Screen, important parameters such as tilt angle, open gap, acceleration plate and curved screen must be taken into account. Because more gaps and high tilt angle cause poor filtration performance but high capacity. Thus, an undesirable situation occurs with ineffective filtration performance.

To avoid this poor filtration performance, important parameters such as gap, tilt angle and curve of the Coanda Screen must be calculated, designed and manufactured accurately for the best utilization of the Coanda Intake Screen. ADENCO is capable to provide accurate and customized design and manufacturing for your applications and requirements with our Coanda Screen Engineers.
