Rendertech Dissolved Air Flotation (DAF) plants provide the solution to many wastewater treatment problems. They are compact, efficient, simple to operate and economical to run. DAFs are used in a variety of industries as a primary method of wastewater treatment before discharge to sewer or irrigation, or for further treatment.

How DAF works. Dissolved air flotation (DAF) provides thickening of sludges (i.e. thickens the sludge) by encouraging the solids to float to the surface, rather than allowing them to sink as in gravity thickening.. DAF is applied to increase the sludge solids concentration when these solids are neutrally buoyant (i.e. neither sink nor float) …

The development of dissolved air flotation (DAF) for drinking water treatment has come a long way. After its pioneering application to water treatment in the 1920s, it was seemingly forgotten until renewed interest in the 1960s in Sweden, Finland, southern Africa and the United Kingdom brought it to attention once more.

The primary DAF effluent was treated by a Phase II system consisting of an aerobic MBBR (moving bed bioreactor) followed by a secondary DAF to clarify biological solids prior to discharge to sewer. The combined (Phases I and II) system (primary DAF + MBBR + secondary DAF) provided BOD, TSS and O&G removals of 97, 99, and 99%, respectively.

Fluence has been developing and continually improving dissolved air flotation (DAF) systems for decades, and has successfully implemented installations in a variety of applications. ...

The present review was motivated by the increasing demand of environmental regulatory agencies for the treatment of oily water generated during industrial activities. Flotation is a promising process for this purpose. Particularly, dissolved air flotation (DAF) is the most indicated technology due to its high efficiency and the …

Dissolved Air Flotation (DAF) is a widely used wastewater treatment process that separates solids, oils, and greases from wastewater, thereby improving its overall quality. This process is particularly effective in treating industrial wastewater, where it plays a crucial role in preventing harmful substances from entering the environment.

Our Dissolved Air Flotation (DAF) Plant is an affordable way to clarify water, wastewater and effluent. The DAF deals effectively with suspended solids (SS), fats, oils and greases (FOG) and Chemical Oxygen Demand (COD). It allows the formation of tiny bubbles by dissolving air into the system. These adhere to the suspended matter causing it to ...
