Most engineers use Hazen’s law as design approach for the settling efficiency.

Hazen’s law links the sett ling velocity [VS] of the target particle with the fl ow rate [Q] and the installed vertical projected surface [AP].

The Hazen-velocity ( VH = Q/AP ) is the most important design parameter.

Particles with a settling velocity that is equal or faster than the Hazen-velocity will be removed
