Static thickener - Degremont® - SUEZ's degremont ® water handbook

The thickener is a circular unit. The sludge suspension is introduced into the centre, inside the centre well. Matter settles according to its respective weight and forms a concentrated sludge blanket.

Sludge Thickening - Degremont®

This technology is usually known as static thickening;. dynamic thickening: concentration that applies mechanical energy. This is mainly: - flotation; - draining/filtration; - centrifugation. Depending on the different types of sludge to be thickened, it can happen unknown for these two processes to be combined in the same plant...

Sludge Dynamic thickening - Degremont®

Its main properties are the speed of the process and dynamic thickening ability to achieve good concentration performances on problematic sludge. The accelerated dynamic thickening of biological sludge is used to: eliminate the large static thickeners which, with this type of sludge, are modestly efficient and the source of...

CHAPTER 3 SLUDGE THICKENING

Thickening is a procedure used to increase the solids content of sludge by removing a portion of the liquid fraction. To illustrate, if waste activated sludge, which is typically pumped from secondary tanks with a content of 0.8% solids, can be thickened to a content of 4% solids, then a fivefold decrease in sludge volume is...

Sludge thickening and dewatering - SUEZ

SUEZ has developed a number of different sludge thickening and dewatering processes. We recommend a technique according to the characteristics of the sludge and the objectives of the treatment process. Two processes can be used to thicken sludge: Static thickening, by gravitational settling. Static thickening calls on...

SLUDGE DEWATERING

It is also very easy to concentrate this type of sludge with a static thickening step just befo- re dewatering. The drawback is that this sludge ferments very easily. 1.2.2.
