Suspended Air® Flotation (SAF®) from Heron Innovators replaces conventional water treatment systems, DAF & high-rate clarifiers.
For over a century, various forms of dissolved air flotation (DAF) systems have been employed for the removal of suspended solids, and fats, oils, and grease from wastewater. The amount of air that can be dissolved in DAF systems is limited by the laws of physics and is usually less than 2 – 4% air by volume. Instead of dissolving air, SAF® generates whitewater (froth) at atmospheric pressure that is 40% air by volume.
Case studies are available for DAF to SAF® conversions which show increased removal performance, reduced power consumption, reduced maintenance, chemistry cost savings, increased hydraulic throughput and solids loading, reduced operator attention, and capital cost avoidance.
