Zone D – Compression Zone (Heavy Mud) At the bottom of the tank, the compacted solids form a dense, almost immobile bed. This zone represents the final stage of dewatering, where gravity alone is no longer sufficient, instead, compression forces drive out the remaining liquid as particles are squeezed closer together under the weight of the bed above.

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.
