Secondary Clarifier

Description

Gravity sedimentation is one of the most frequently used processes in wastewater treatment. Many wastewaters contain settlable suspended solids that can be removed under quiescent conditions. Particles, solid, liquid, or gaseous that have a different density from that of the suspension medium (water), will settle downward because of gravity or rise to the top because of buoyancy. In other cases where suspended materials do not settle readily, upstream unit processes are used to convert colloidal (nonsettlable suspended solids) and soluble pollutants into settlable suspended solids for gravity sedimentation removal. Suspended solids removal is important because of the pollutants associated with the removed solids, such as organics, nutrients (nitrogen, phosphorus), and heavy metals.

Gravity sedimentation occurs in basins frequently called clarifiers.
Secondary clarifiers are used to remove the settlable suspended solids created in biological treatment processes such as the activated sludge and trickling filter process.
Aquatec Maxcon is able to offer various types of Primary and Secondary clarifiers.
