Description: Flotation Without Dissolved Air! Suspended Air Flotation (SAF™) Systems Suspended Air® Flotation (SAF™) is a cutting edge wastewater treatment offered by Heron Innovators (See Wastewater Engineering Treatment and Resource Recovery, Metcalf & Eddy/AECOM, pp. 409-10.) This advanced system is the result of over 14 years of development and represents a leap forward in flotation separation technology. Suspended Air Flotation (SAF™) Systems Heron’s SAF™ Generator and ClearFloater™ Flotation Separator are engineered with features that are solution based, and offered as complete skid-mounted systems, mobile units mounted on trailers, or custom configurations ready for seamless integration. Heron’s scientific and engineering expertise was fully brought to bear to create not only a turn-key solution but to also provide DAF retrofits to SAF, allowing a broader market to benefit from SAF’s advantages.
