Heron Innovators, Inc., established 1998
The innovation behind Suspended Air® Flotation (SAF®) was invented by the late Dr. Felix Sebba in 1975. Since then, the engineering and science team at Heron Innovators has advanced this technology establishing flotation without dissolved air as the next level in liquid/solid separation for water and wastewater treatment and solids thickening.
Since Heron Innovators is located in California's agricultural Central Valley, Suspended Air® Flotation (SAF®)'s first installations were in the food processing industry. Installations have expanded to other industries across the U.S., Mexico, and Canada. The SAF® process is applied anywhere physical/chemical separation via flotation is a viable solution to water quality. SAF® advances previous traditional process systems (i.e. dissolved air flotation, DAF, induced air flotation, IAF, Induced Gas Flotation, IGF, enhanced clarification, cavitation air flotation, CAF, and other micro-bubble generators) through flotation without dissolved air.
