Thickening of sludges is commonly utilized at water and wastewater treatment plants for solid/liquid sepa ration. Thickening is characterized by the existence of a well-defined interface between the solids and the liq uid. In batch gravity thickening, the rate of subsidence (or settling velocity) of the interface decreases if the sol
