Dried sludge is discharged in the form of flakes by combining the dryer with VOLUTE TM Dewatering Press, minimizing the scatters of dried sludge making it easier to handle. In addition, it offers the advantage of dried sludge being less likely to decay than dewatered cake, consequently providing less odor during the temporary storage of the sludge.

Sludge drying | Sludge Processing

Sludge drying properties. Sludges of different origins and characteristics exhibit different behaviours when drying. These are most readily observed by correlating the mass water flux – the mass of water evaporated per unit surface area of solids per unit time (kg m-2 s-1) – against the moisture content of the sludge.This correlation normally reveals the three different drying phases:

Drying beds | Sludge Processing

Drying beds. Sludge drying beds provide sludge dewatering by allowing the liquid to both drain under gravity through a permeable medium on which the sludge sits, and to evaporate under ambient conditions. The sludge is spread as a thin (up to 300 mm) layer over a porous bed made up of layers of sand and gravel. Topic.

Paddle dryers | Sludge Processing

Paddle dryers are based on externally-heated paddles (or blades) rotating in the mass of sludge solids. There are normally either two or four sets of blades which rotate together to continuously cut into and stir the sludge solid lumps into smaller particles to continuously replenish the drying surface.
