We are one of the widely acclaimed manufacturers and suppliers of Dissolved Air Flotation Units. Our offered dissolved air flotation units are widely used for the purification of wastewater from oil industry, dairy industry, food industry, Etc.
Dissolved Air Flotation (DAF) is a clarification process for the separation of solids, grease and oils. It works by producing a stream of micro-fine air bubbles that attach to solids and float them to the surface where they can be removed by a surface scraping mechanism. DAF is ideally suited to particles and flocs that are slow settling, neutral density or buoyant. This is particularly relevant to food and other industries where solids are light and voluminous and so not suited to settling. DAF also takes up considerably less space than settling methods.
Our offered dissolved air flotation units are equipped with flash mixer and Flocculator. Chemical pretreatment often improves DAF solids removal efficiencies.
DAF float often contains 2 to 10 percent solids. The solids may need to be dewatered before disposal to reduce the sludge volume by reducing water content. Float dewatering is usually performed by using one of the following technologies:
- Filter press
- Belt filter press
- Centrifuge
