 SAF® process systems exceed every comparable measurement or metric relating to traditional flotation methods, such as DAF, CAF, IAF, IGF and microbubble technologies. Flotation without dissolved air (SAF®) is not confined by the physics that apply to methods which dissolves air or gas in water.

Suspended Air® Flotation (SAF®) may use methane gas instead of air eliminating oxygen in the treatment process similar to Induced Gas Flotation, IGF. SAF® Froth is not generated by impellers, eductors or spargers. Additionally, SAF® systems do not require parallel plate packing material to achieve very high efficiencies.

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.
