Multimedia (sand) Filtration Calculation - Lenntech

For industrial water filtration purposes vertical filter bed speeds (ideal service flows) varying between 10 m/h and 25 m/h are used depending on the quality of the to be treated water. The higher the total suspended solids (TSS indicated in mg/l) content or the more turbid the water, the slower the vertical filter bed speed.

Sand filter - Wikipedia

2019-10-17  For a pressurized rapid sand bed filter this occurs when the pressure drop is around 0.5 bar. The backwash fluid is pumped backwards through the bed until it is fluidized and has expanded by up to about 30% (the sand grains start to mix and as they rub together they drive off the particulate solids). ... Slow sand filter design
