Riffat, R. (2012) - Fundamentals of Wastewater Treatment and Engineering. CRC Press

The document discusses recommended minimum approach velocities for bar screens in wastewater treatment. Several sources recommend minimum velocities between 0.45 m/s and 0.9 m/s to prevent grit deposition while maintaining solids removal. Velocities below 0.45 m/s can result in increased solids deposition in the screen channel. Screen channel lengths are typically recommended between 2 to 3 meters.
