Continuous Chain Raked Screen

Inlet Works and Storm Overflow Screening Equipment

The Continuous Chain Raked Screen is used on inlet works and storm overflows where large concentrations of debris are expected.

Continuous Chain Raked Screen is a front raked bar screen which is best suited to pumped flow systems. Grid depths are selected to suit the water levels that the screen will see in operation. The gap between the top of the grid and discharge point is bridged by a continuous series of solid debris plates. The rakes pull trapped screenings up the bars and debris plates, to the discharge point.
