Settling and Thickening Test Procedure
Place pulp in a measuring cylinder and make up to say 1000 ml mark with water. Shake thoroughly after addition of flocculant. Allow to settle quiescently and note interface depth as a function of time (seconds). Flocculation is a time function following an empirical relationship. C= k tm where C is the suspended solids concentration.

Sludge Dewatering and Thickening
Sludge can be thickened to 8-10% total solids. A pump then sends the sludge to the anaerobic digester. At the top of the basin is the scum collector and discharge. A gravity thickener uses gravitational forces to separate water from sludge and is mainly used on primary sludge at plants still using this technology.
