Dissolved Air Flotation


The Pan America Environmental DAF (Dissolved Air Flotation) series is a family of  above grade flotation systems can be provided for many applications where solids, oils, fuels and many other products are present. Applications can include: Food processing, animal processing, FRAC water, Industrial water, manufacturing wastewaters, refineries, steel mill process water, heavy equipment washwater. The DAF is one of the most flexible and capable pieces of wastewater treatment equipment available.


  • Proven traditional design for reliability
  • 5 Different designs to choose from
  • Flow rates from 5 to 2000 + GPM
  • Construction: Coated carbon steel,  304/316 SS, polypropylene/polyethylene, concrete

Process Overview

The DAF design is most commonly used wherever crudes, oils, fuels and solids can come into contact with a wastestream.

How It Works

The DAF Dissolved Air Flotation (DAF) is the use of micro-bubble flotation as a solid/liquid or liquid/liquid (or both) separation method that is widely used in industrial and domestic wastewater treatment processes. Dissolved Air Flotation, is a well-established separation process that uses micro-bubbles as a carrier phase to remove solids, ions, macromolecules, fibers and other materials, BOD, COD reduction and for sludge thickening. Air Flotation offers process advantages over such processes as filtration, precipitation, or adsorption using natural and synthetic sorbents and medias. The advantages include better treated-water quality, rapid startup, high rate operation, and a thicker sludge, shorter sludge residence time in a secondary clarifier stage and flexibility in changing the operation parameters as the result of active sludge separation.
