Sludge Dewatering

Sludge Dewatering is the process of removing water from sludge to reduce its volume and make it easier to handle, transport, and dispose of.

Key methods include:

Belt Filter Press – Uses belts to squeeze water from sludge.

Centrifugation – Spins sludge to separate water based on density.

Vacuum Filtration – Uses a vacuum to remove water through a filter.

Screw Press – Compresses sludge to expel water.

Drying Beds – Sludge naturally dries through evaporation.

Filter Press – Applies pressure to extract water from sludge.

Geotextile Bags – Fabric bags filter out water from sludge.

Benefits:

Reduces sludge volume.

Recovers water for reuse.

Lowers disposal costs.

Sludge dewatering helps improve wastewater treatment efficiency and supports sustainability.
