No additional air tanks, controls, or compressed air is required.  \nThe following materials are available for construction of the EDUR DAF Pumps in the case of the following pH levels for the wastewater stream that you will be pumping:  \npH value less than 3   Stainless Steel  \npH value 3 to 5.9   Bronze  \npH value 6 to 10   Gray Cast Iron  \npH value 11 to 14   Gray Cast Iron (all iron)  \nApplication  \nThe EDUR dissolved air flotation (DAF) pump is a very effective way to separate suspended solids and emulsified oils from industrial waste streams. Microscopic air bubbles are produced and mixed with waste water containing the suspended contaminates. The small bubbles attach themselves to the suspended particles, which gives them a net positive buoyancy. These buoyant clusters of particles and bubbles rise smoothly to the surface forming a float which is removed by skimming. Air and recycled “clean” effluent is introduced to the pump suction. The proportion of air/water is controlled through simple valves. Under pump discharge pressure this air effluent mixture becomes supersaturated with air microbubbles. This enriched stream is then recycled back into the dirty effluent and fed to the DAF unit. Up to 35% air can be achieved with 100% saturation and microbubble size smaller than 30 micron.  \nDesign Features  \nFor DAF applications, as specified above, EDUR pumps meet the following requirements:  \n• Long service life because of low wear caused by the inevitable contamination of liquids with solid particles. Proper selection of materials of construction is critical.  \n• Steady pumping characteristics even with changing points of operation.  \n• Sufficient blending of effluent and air to obtain maximum entrainment of air microbubbles @ 30 micron size.  \nNormal standard pumps are not able to meet these requirements. The hydraulic parts of EDUR pumps have been specially designed to cope with problems which arise when pumping effluent/air mixtures. The distinctive feature of the EDUR pump is the impeller, open on both sides, and the innovative hydraulic design of the impeller blades.  \nDesign Features and Specifications  \nBuilt-in Economics and Efficiencies  \nA DAF system with use of the EDUR DAF Pump providing air enriched recycle effluent. A typical 100 GPM EDUR Recycle Pump provides 12% air with 93% saturation. Total Power: 10 HP.  \nA typical DAF system avaiable now. Note the required air tank and controls for providing air entrainment. This is all eliminated with the use of the EDUR DAF Pump.  \nTypical unit: 100 GPM recycle, 9% air at 80% entrainment.
