Sedimentation Sludge from Water Treatment Plants
Industry Background
During raw water treatment, water treatment plants generate sedimentation sludge through coagulation and settling processes to remove suspended solids and impurities. This sludge is mainly discharged from sedimentation tank desludging systems and is characterised by high moisture content, low solids concentration, and relatively stable composition.
As plant capacities expand and environmental management standards increase, the standardised treatment of sedimentation sludge has become an increasingly important part of water treatment plant operations.
Technical Approach
Considering the low solids concentration and high moisture content of sedimentation sludge, dewatering systems are generally required to combine continuous operation with stable performance. With appropriate process configuration and equipment selection, dewatering equipment can adapt to variations in water quality and sludge discharge conditions, supporting effective sludge volume reduction and more stable downstream handling and disposal.
In practical applications, this technical approach focuses on operational reliability, ease of maintenance, and compatibility with existing water treatment processes.
On-site Photos
The photos below show a Haibar dewatering system installed in 2022 at a municipal water treatment plant in Suzhou, China, treating sedimentation sludge generated from sedimentation tank desludging processes. The equipment forms a key part of the plant’s sludge volume reduction system, supporting continuous and stable operation.
On-site operation demonstrates reliable performance under varying water quality and sludge discharge conditions. The system operates smoothly with a high level of automation, helping to reduce routine operational and maintenance workloads and supporting long-term operational requirements.
