Thickening, dewatering & drying | Sludge Processing

Thickening, dewatering & drying. Sludge drying refers to processes where moisture is removed from sludge as water vapour. These processes often require pre-treatment ('conditioning'). With sludge thickening or dewatering, moisture is removed as a liquid. Topic.

Processes and technologies for sludge treatment ...

The main thickening processes for sludge treatment are based on the following: Gravity: The sludge enters in the central area; the thickened sludge collects in the lower part and the supernatant is left in the upper part. This system is used in primary, physicochemical and mixed sludges that decant well by gravity. Biological sludge decants slowly.
