Hindered systems and rheology - Chapter 6

Continuous thickener design tool and utilities

Online thickener design, where you can enter your inputs and the simulation provides tabular data for the required thickener area, and diameter. In accordance with the Coe and Clevenger approach to thickener design, the largest thickener area is recommended for the design.

In addition, there are sedimentation utilities for the calculation of the free settling velocity of a particle using the input of particle diameter, and for the conversion between solids concentration by weight (i.e. mass) and concentration by volume. The latter is used in the design models.
