Suspended Air Flotation (SAF®) Systems
Suspended Air® Flotation (SAF®) is a cutting edge wastewater treatment process which floats suspended solids without dissolving air. Heron Innovators, Inc. is the only manufacturer of the SAF® (See Wastewater Engineering Treatment and Resource Recovery, Metcalf & Eddy/AECOM, pp. 409-10.). This advanced system is the result of over 20 years experience and represents a leap forward in flotation separation technology.
Heron Innovators’ 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 Innovators’ scientific and engineering expertise was fully brought to bear to create not only a turn-key solution but to also provides DAF retrofits, allowing a broader market to benefit from SAF®’s advantages.
