Clarifier - an overview | ScienceDirect Topics

The green liquor clarifier is a settling tank used to remove dregs by sedimentation before the green liquor is recausticized as shown in Fig. 17.13.It can also serve as a storage tank for green liquor and should provide at least 12 h supply of green liquor. Since the mid-1960s, single-compartment clarifiers have been used in place of the older multicompartment clarifiers.

How a Thickener Works

Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat-bottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle as long as required, the top liquid was decanted, the settled solids were ...

Thickeners Clarifiers - Chemical Engineering

Thickeners and clarifiers use slowly rotating rake arms to separate solid particulate. A liquid feed with suspended solids is fed into a tank with a diameter of 5 to 500 feet. As the particles settle, angled rake arms move the concentrated slurry toward the center of the tank, where it is removed.

Beginners Guide to Thickeners - Outotec

Many thickener installations operate with water recovery below design limits largely through conservative control and low prioritization of thickener optimization. The operation of the thickener must accommodate fluctuations – control for disturbances – in the process feed stream to deliver a clear overflow and thickened underflow.
