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. This

Sludge Thickening an overview ScienceDirect Topics

There are several thickener designs in use; most are of the settlement type developed for industrial applications, which uses heavy duty scrapers with a picket fence attachment. A design developed in the UK by the WRc ( Warden, 1983 ), for waterworks sludge thickening applications, consists of a cylindrical tank of water depth 2–3.5 m with a shallow sloping floor (1 in 20).

The gas formed will cause the flotation of the solids in the thickener. Chemicals like chlorine (CI 2) need to be added to inhibit the biological activity. A well operated thickener will have a solids recovery of about 95% [3]. Design of Thickeners The thickening process takes place in a settling tank with long-enough solids retention time. For example in secondary clarifiers of activated

How a Thickener Works 911metallurgist

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

Sludge recirculation settling tank thickener : the

For the same polymer consumption, we have found a host of consequences: floc is even denser and forms a sort of «self-ballast» that is more suited to high velocities; the concentration of sludge extracted rises. Most of the time, this concentration is twice as high and exceeds that of the static thickener.

Conventional Thickeners Solid Liquid Separation

The overflow weir that surrounds the tank ensures that the flow that leaves the thickener is distributed evenly in terms of m3/hr/m weir length. During the first year or so differential settling of the tank foundations may cause an uneven distribution so that the entire flow passes over the lower part of the weir which results in high velocities and drag of fines to the overflow launder

Sludge Thickening Sewage Treatment Reverse Osmosis

Sludge is usually pumped continuously from the settling tank to the thickener which has a low overflow rate so that the excess water overflows and the sludge solids concentrate in the bottom. A blanket of sludge is maintained by controlled removal which may be continuous at a low rate. A sludge with a solids content of 8 -10 percent or more can be produced by this method. This means that with
