Separation
Dissolved Air Flotation
A dissolved air flotation (DAF) unit for separating suspended material from wastewater. Fine bubbles carry floatable solids to the surface for collection.
Share the wastewater flow, suspended solids and oil or grease levels. If DAF sludge also needs dewatering, include its expected volume and solids concentration.
Separate Suspended Solids and Grease
How It Works
Air is dissolved in a pressurized water stream. As pressure is released in the flotation tank, fine bubbles attach to suspended solids and grease. The float rises for surface skimming, while clarified water is collected separately.
Configuration and Applications
Typical evaluation points include industrial wastewater pretreatment, water reuse and pretreatment ahead of membrane or biological processes. The flotation and sludge handling equipment are sized together.
What to Send for Sizing
Share average and peak flow, suspended solids, oil and grease, pH and the required outlet water quality. Include any jar-test data and the plan for handling floated sludge.
