SAF™ technology has been installed at municipal treatment facilities to thicken solids from Waste Activated Sludge (WAS) and digesters, provide enhanced primacy clarification, primary clarification with grit removal, secondary clarification with solids thickening, and algae removal from holding pond effluent.

As municipal facilities focus on improving their environmental stewardship, SAF™ offers many advantages:

  • Water Reclamation – SAF™ can help in attaining California Title 22 standards
  • Lower Greenhouse Gas Emissions – Significantly lower power consumption than traditional Dissolved Air Flotation treatment technology
  • Small footprint – Mobile, trailer and skid-mounted systems offer alternatives to fixed, concrete facilities. Significant reductions in equipment footprint, power consumption and demand for chemical conditioning greatly reduce environmental impacts.

Standard system features include an influent flow meter, dual compartment conditioning tank, coagulant metering pump, polymer activation and aging system, Suspended Air® Emulsion Generator, ClearFloater™ Flotation Separator, dewatering conveyor, and process control panel. A pH sensor/controller and acid/base fixed PID loops can be supplied as an option.

How Did It All Begin?

The first applications of SAF™ were in the food processing industry because the company was located in California’s agricultural Central Valley and there was a need for treating wastewater from a variety of food processors. Since then installations have expanded to other industries that formerly relied on the traditional DAF approach. The Suspended Air® Flotation Process can be and is applied in any application where physical/chemical separation via flotation is a viable alternative.
