Sludge dewatering

Sludge dewatering is the process of reducing the water content of the sludge after primary and secondary settling. Filter presses, centrifuges or special vacuum units are used.

Dewatering reduces the volume of sludge, making it easier to transport and dispose of. The sludge becomes denser and more suitable for composting, incineration or use in production processes. This stage is important for saving space and resources in wastewater treatment plants.
