Dissolved Air Flotation Systems  

EnviroVac’s Dissolved Air Flotation systems “DAF” are designed to remove suspended solids, oil and grease, heavy metals, BOD, COD, and VOCs from a wide variety of industrial waste streams. This is achieved by utilizing a unique air dissolving system to produce a high level of air saturation and extremely small micro bubbles in the process water. Microbubbles are entrained by flocculating in the presence of dissolved air. This causes them to rapidly float to the surface of the DAF for removal by a sludge raking system, leaving only the clarified water behind.

EnviroVac designs and manufactures DAF systems ranging from small pilot systems to high flow industrial wastewater treatment systems with flow rates ranging from 10 to 1,000 gpm (0.04 to 3.8 m3/min).
