Secondary Clarification
Plate Settlers for Post-Biological Treatment Clarification
High-rate secondary clarification following activated sludge, MBBR, or other biological treatment processes.
Secondary Clarification
Secondary clarifiers separate biological solids (mixed liquor suspended solids) from treated effluent following biological treatment. Conventional secondary clarifiers require large surface areas due to the need for a clear settling zone and sludge thickening zone.
Plate settlers can be applied to secondary clarification to increase the settling capacity of existing secondary clarifiers or to provide compact new-build secondary clarification. This is especially effective for applications with well-settling activated sludge or MBBR biofilm solids.
Secondary plate settler clarification is an excellent option for WWTP capacity upgrades where the secondary clarifier is the bottleneck.
Key Benefits
Capacity Boost
Increase secondary clarifier capacity by 200–300% via plate settler retrofit.
Better Effluent
Lower effluent TSS enables compliance with stringent discharge limits.
WWTP Upgrade Path
Address secondary clarifier bottlenecks without new construction.
