Hindered Settling - Chapter 6
This section contains resources for hindered settling (Chapter 6) including: an online simulation of continuous thickener design using the Coe and Clevenger approach; video explanation of the modelling taking place in the simulation; a video explanation of the force balance in hindered settling and options for permeability modelling; and utilities for predicting the single particle settling velocity (free settling) from the input of particle diameter and an online calculator to convert from solids concentration by mass, to concentration by volume fraction, for a suspension.
