    It is essential in clarifier design that the settling rate of the particle is greater than the upward velocity in the plate pack or the particle will be carried out. This is where it gets tricky. Sizing a clarifier is done on a Hydraulic Loading Ratio or HLR that is defined as ratio of GPM/FT2 of projected surface area.
