Suspended Air® Flotation (SAF®) technology has been installed at municipal treatment facilities to thicken solids from Waste Activated Sludge (WAS) and digesters, provide enhanced and primary clarification (with or without grit removal), secondary clarification with solids thickening, and algae removal from holding pond effluent or surface water from lakes.
As municipal facilities focus on improving their environmental stewardship, SAF® offers many advantages:
The SAF® process is applied anywhere physical/chemical separation via flotation is a viable solution to water quality. 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 established SAF® as the next level in liquid/solid separation for water and wastewater treatment and solids thickening. Heron Innovators fabricates the proprietary SAF® generators, flotation tanks, and the mechanical and electrical process equipment used in each installation.
