Screening Considerations – A Guide to Selection

Screen channels should be designed for approach velocities between 2fps (0.6m/s) and 3.3fps (1m/s). If velocities drop below 2fps, grit and screenings might accumulated upstream of the screen. Accumulated debris might lead to functional problems once a peak flow flushes that debris to the screens within a short time period
