Dissolved Air Floatation (DAF) involves a process of separating oils and solid particles from water by attaching the oils and solids to micro air bubbles to decrease the density of the particles causing them to float. Flotation is the ideal process for separation of lesser dense/ lighter impurities which includes Oil, Grease, Fats that have tendency to float to the water surface. Such solids would either sediment very slowly or would remain suspended. The process of rising solids is known as. The froth is skimmed off the surface and further processed in the sludge treatment.
SeVAMI® -DAF system is specially designed to maintain excellent laminar flow conditions, and especially designed for the removal/recovery of solids, fats, oil, grease from wastewater and process water & paper mill applications.
