Drums screen rate

Apr 23, 2020

BEAUDREY outside-to-inside drum screens arrest the small debris contained in a large flow of water in industrial or power plants and are especially recommended for very large flow rates. They resist high levels of head-loss and provide a compact civil structure. Fully automatic, safe with low maintenance requirements

    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
