After undergoing biological treatment, wastewater enters the secondary sedimentation tank (SST) for sludge-water separation. Only the clarified effluent that meets discharge standards can be released. At the same time, a certain concentration of retu...

Common types of secondary clarifiers include horizontal flow, radial flow, and inclined plate/tube sedimentation tanks. 1. Horizontal Flow Sedimentation Tank Horizontal flow tanks are typically rectangular. Water enters through an inlet zone where f...

Sedimentation tanks (including primary and secondary clarifiers) are the core solid-liquid separation units in wastewater treatment processes. Their performance directly affects water purification efficiency, the stability of subsequent processes, an...
