The mechanism of orthokinetic flocculation is assessed in relation to the geometric properties of laminar flow in an idealized capillary model of a granular filter. The velocity gradient (G), which controls the ultimate floc size, Is shown to have a significant effect on the removal efficiency of the filter.
