Clarifying Treatment Dissolved Air Flotation Provides

With mechanical sludge removal, the DAF sludge can be quite thick (2 to 5 percent solids), which eliminates the need for thickening before dewatering. Because of air attachment, polymer is not required for stable performance, as opposed to high rate settling processes that must use polymer to attach particles to ballast.
