Sludge Thickening - an overview ScienceDirect Topics

3.12.7.2 Gravity Thickening. Gravity thickening works on the simple principle of the force of gravity being greater on denser materials. Sludge from the clarifiers is fed from a center well to the tank, and gravity then separates the solids, which settle downward and compact at the bottom of the tank.

Sludge Thickening - an overview ScienceDirect Topics

The thickeners must be preceded by flow balancing tanks to contain and mix intermittent sludge discharges and feed the thickeners at a consistent concentration and uniform rate (Fig. 13.1). In applications where used washwater (without settlement) is mixed with clarifier sludge, the sizing of the flow balancing tanks becomes critical because of ...

Alfa Laval - AS-H Belt Thickener

How does the gra vity belt thickener work?. The sl udge thickener works on the principle of separating liquid from solids by gravity drainage through a slowly rolling belt cloth. It uses a sludge polymer mixing valve with an adjustable lever arm to ensure sufficient turbulent sludge/polymer mixing.. After this, the ramp feeding section delivers a consistent load across the filtration area to ...
