Dissolved Air Flotation Systems

Dissolved Air Floatation (DAF) technology has been used with great success over the years to float contaminates from wastewater. PCS's flotation systems are well-suited for the removal of light solids such as oils, fibers, proteins, starches, blood, inks, dyes, and other substances which do not settle well by gravity. Air is dissolved into a recycled portion of the treated water flow and is mixed with the untreated water entering the flotation cell. As the air comes out of solution, it forms sub-micron bubbles which attach themselves to the suspended solids and oils. These solids float to the surface where a simple, single shaft skimmer removes them for further processing or disposal. Enhanced removal by flotation is available by using a three-stage dissolved air floatation (DAF) system with recycled water mixed individually into the flow at each of the three stages of the system. These individualized treatment cells increase significantly the quality and efficiency of the wastewater treatment as the flow passes to each stage of treatment. The net result is more thorough solids removal rates through flotation.

Typical applications for DAF's are found in the food and chemical processing facilities, pulp and paper processing, and any facility which requires the reduction of oils, fibers, and other light solids.
