Industry standard for large, raw water channel screening equipment.
Our Dual Flow traveling water screens have become the industry standard design for Intake screening. This design completely eliminates debris carryover, offers nearly twice the screening area of a Thru-Flow screen and is ideal for high water volumes and heavy debris removal. Building on the legacy of Rex® and Link-Belt® products with the technologies of today, we provide Dual Flow screens with lower maintenance, greater reliability, and the know-how to meet your specific requirements.
Evoqua's Dual Flow intake traveling water screen system consists of a series of overlapping inclined self-draining screen trays. They are fastened to two steel sidebar bushed chain that operate over large head sprockets which are mounted on a structural drive.
Large volumes of raw water pass through the submerged traveling water screens when they are moving up out of the water, and when they are passing down through the water as well. Debris is screened from the raw water and washed from the screens by high-pressure, overlapping water sprays across the entire back of the screen trays. The debris (sticks, logs, leaves, etc.) is washed into a trough for disposal.
We also have the capability and expertise to retrofit our Dual Flow design to fit your Thru-Flow intake channel with no civil work modifications.
