sludge thickener

Zone settling occurs in lime-softening, sedimentation, active sludge sedimentation and sludge thickeners.

Another style of similar equipment is the Sludge Thickener, consisting of a picket fence style stirrer with centre drive mechanism.

Types of pre-thickeners include centrifugal sludge thickeners rotary drum sludge thickeners and belt filter presses.

The rest is sent to the sludge thickener where the moisture is removed, the separated liquids sent back to the treatment system and the sludge is sent to the boiler heaters where it is burned.

The treatment of the effluent includes its passage through a pump and piping system, that is, through a primary clarifier, a mixing tank, a cooling tower, a UNOX reactor, one of two secondary clarifiers and, finally, a sludge thickener.
