Enhanced Dissolved Air Flotation (E-DAF) System

Dissolved air flotation (DAF) is a clarification process that utilizes air to remove suspended matter from the surface of treated water. DAF works by dissolving air under pressure and then releasing millions of tiny air bubbles into the water at atmospheric pressure. This process allows the dissolved air bubbles to adhere to a suspended …

Dissolved Air Flotation Applications for DAF Flotation

Operating Principle. Dissolved air flotation is a method for separating and removing sus-pended solids from liquid based on changes in the solubility of gas as pressure varies. Air is dissolved under pressure in a clean liquid, usually recycled effluent from the DAF unit, and injected into the raw feed stream.

Dissolved-Air Flotation(DAF) Equipment For Wastewater …

The operation of a dissolved air flotation (DAF) machine typically involves the following steps: Wastewater or process stream is fed into the DAF tank. Recirculated water is pressurized and saturated with air. The pressurized water is released into the DAF tank, creating tiny air bubbles that attach to the suspended solids.

Sludge treatment − dissolved air flotation thickening

The DAF process works by dissolving air under pressure in water to achieve saturation concentrations. When the pressure is released, air is precipitated as small bubbles which rise through the vessel. The bubbles come into contact with the sludge particles, sweeping them up to the surface where they form a scum.
