Dissolved Air Flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater …
The pulp and paper industry consumes a huge amount of water and releases more polluted and colored wastewater every year. Many conventional techniques are used in the treatment of paper industry wastewater. However, for color removal from paper mill effluent, there is no proven method so far, on an …
Dissolved Air Flotation is a proven and effective physical/chemical technology for treating a variety of wastewater streams. DAF systems are designed to remove total suspended solids (TSS), biochemical oxygen demand (BOD), and oils …
Its wastewater contains approximately 580 mg/L of fats. With local infrastructure straining to treat its wastewater, the company's bills soon became too high. Ekolat chose Fluence to install a DAF system that helped remove virtually all fats from its wastewater, realizing significant savings on municipal treatment with no break in production.
This study aims to review the efficiency of the dissolved air flotation (DAF) technique in a wide variety of applications in the agricultural, industrial, domestic, and municipal sectors, which ...

What Is Dissolved Air Flotation Water Treatment? Dissolved air flotation (DAF) is a water treatment process designed to remove oils, solids, and greases. In fact, the process helps clarify wastewaters – and other waters – by eliminating different types of suspended matter. The DAF process dissolves air in the water under pressure – then ...
Since 2000, more than 50 drinking water treatment plants (WTP) in North America have used DAF, with capacities ranging from 0.5 MGD to 290 MGD. DAF is an alternative clarification process that uses micro air bubbles to attach and float flocculated particles and suspended solids to the water surface for removal (see Fig. 1).

De Pinho et al. (2000) compared the efficiency of (1) ultrafiltration and (2) ultrafiltration plus dissolved air flotation. The results showed 54%, 88%, removal of TOC, color, and SS, respectively by ultrafiltration alone. Ultrafiltration plus dissolved air flotation resulted in 65%, 90% and removal of TOC, color, and SS, respectively.
Dairy Wastewater can be treated in the best way possible by using biological methods such as Active Sludge Process. (Lateef et al., 2013). This method primarily depends upon the characteristics of waste water and kinetic coefficient and knowledge of the microorganisms responsible for the treatment process.
