A DAF is typically installed after a primary screen. The DAF removes the smaller particulate that pass through the screen. A DAF operates on the following principle of pressurizing the water with air to increase the air saturation into the water. The water then flows across a backpressure valve (the pressure is relieved), thereby allowing the air to come out of solution (effervesce) out of the water. This is the same reaction that happens when you open a 7-up bottle and the bubbles come out of solution causing the bubbling. The micro bubbles produced in the DAF adhere to the small particulates in the wastewater. Once the bubble and particle adhere, they quickly float to the surface of the DAF where they are scraped off as a sludge.
