Dissolved Air Flotation Process Flow Diagram

Dissolved air flotation provides alternative for treating raw water with light particles.

Dissolved air flotation process flow diagram.

The released air forms tiny bubbles which adhere to the suspended matter. H2flow daf process description drawings. Dissolved air flotation theory of operation. 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 r5 daf is a pre engineered modular and skid mounted dissolved air flotation unit with variable tank sizes flow and recycle rates. Coco daff counter current dissolved air flotation filtration is an innovative combined flotation filtration design in which air and water flow counter current as against co current in the conventional dissolved air flotation process fig. If you are unfamiliar with basic daf separator design principles a review of the dissolved air flotation theory of operation might prove helpful this basic document covers stokes law and other basic separation concepts.

Dissolved air flotation is an alternative clarification process ideal for treating raw water with light particles such as algae or color causing organics and at low temperatures when sedimentation is not as effective. It provides a flexible easy to install and affordable solution for smaller municipal and commercial water and wastewater treatment operations plant pilot testing and backup for unexpected plant equipment. Figure 7 104 presents a diagram of a daf system complete with chemical coagulation and sludge handling equipment.

Dissolved air flotation daf is a water treatment process. The dissolved air flotation process takes advantage of the principles described above. Dissolved air flotation daf is a technology used extensively for wastewater treatment in food plants oil gas mining pulp paper many major industries and municipal wastewater plants. Daf dissolved air flotation and ace air charged entrainment combined into one attached and entrained air for higher separation efficiencies.
