The above multi-media filtration calculator calculates the diameter of a round multi-media filter (MMF) based on the filter bed speed as input. 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 ...
