Screenmat Step Screens

The Screenmat is a step screen suited primarily for screening of sewage. The Screenmat is typically installed in a channel at an inclination of 30 degrees to 40 degrees.

The Screenmat step screen consists of a series of stationary and mobile steps alternating with each other. As the effluent flows through the Screenmat, a screening mat develops along the surface of the screen. The mobile steps progressively lift the mat of solids along the inclination of the screen. On reaching the top of the Screenmat, the solids are discharged by gravity into a screw conveyor or similar device. The low-inclination angle ensures that a screening mat is retained continuously during the entire operation and prevents the roll down encountered in steeper screens.

A consistent screening mat contributes to a uniform and high-solids capture rate.
The Screenmat step screen is capable of handling flows of up to 23,775 gpm / 5,400 m³/hr through a single unit.
