Clarifier

20 · Economy favors using small tanks; but if flow rate through the tank is too high, most particles will not have sufficient time to settle, and will be carried with the treated water. Considerable attention is focused on reducing water inlet and outlet velocities to minimize turbulence and promote effective settling throughout available tank volume.

Liquid–Solid Separation in Gold Processing

A rakeless ultra-high-rate thickener would be very similar to the high rate thickener as they generally produce similar underflow densities. The ultra-high-rate thickener is sized mainly on hydraulic loading and would therefore have a smaller diameter (and hence, smaller footprint) than the equivalent high-rate thickener.
