Dissolved air flotationDAFis a water treatment process that clarifies wastewatersor other watersby the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin.
The flotation process in wastewater treatment plays a pivotal role in meeting environmental discharge compliances and regulations. Dissolved Air Flotation Systems for Water Treatments. Dissolved air flotation is a process utilized across a myriad of industries. In fact, water or wastewater treatment creates mineral and organic sludges from ...
Principal of Operation – Dissolved Air Flotation DAF or Dissolved Air Flotation is a simple but ingenious concept. Make tiny bubbles by dissolving gasair typicallyinto water under pressure according to Henrys Law of gas whereby the pressure applied to gas will dissolve it into liquidwater .
Flotation. Dissolved air is the most common type of flotation gas used in potable water treatment. The dissolved air flotationDAFprocess mixes a clarified stream from the outlet of the unit with air at 3–9 bar, to produce a supersaturated

Dissolved air flotationDAFis a proven and effective physical/chemical technology for treating a variety of industrial and municipal process and wastewater streams. DAF systems are commonly used for the removal of oilsandgreases and suspended solids to meet a variety of treatment goals including:
The patented poseidon* DAF uses dissolved air flotation technology to separate fine dispersed particles from process water and wastewater to reach your desired specifi ions. With the use of internal separation plates, high efficiency clarifi ion is provided in modern, compact DAF designs.
A variety of different industries need to treat wastewater and rid it of various contaminants. One of the most effective ways to do so is with Dissolved Air Flotation equipment used in a system of the same name, also known as DAF. The DAF wastewater treatment system consists of many parts and has an entire science behind it.
