Installation Of A SAF™ System Replacing DAFs (Dissolved Air Flotation) For The Meat Packing Industry

Installation of a SAF™ System Replacing DAFs for the Meat Packing Industry

( Click Image to Enlarge )

Heron Innovators cutting-edge Suspended Air® Flotation (SAF™) system retrofitting capability was the solution for a Kansas-based meat packaging customer. The SAF™ system, with its smaller footprint (12% of the DAF footprint) and cost-effective technology, dramatically improves bleachable tallow recovery. The Suspended Air® Emulsion, with its high air content, is key to the process improvement. A marked reduction of TSS, oil, and grease in the wastewater was immediately noticeable.

Formed from 304 stainless steel, the SAF2000 system includes a Model F200 froth generator, Model CF2000 ClearFloater™ flotation tank, and a Heron Innovators-designed and fabricated polymer dilution and aging system, with a maximum system height of approximately 13 ft. This SAF™ system replaced four existing 40-ft. diameter dissolved air flotation (DAF) systems, reducing the energy used in the treatment process and increasing the amount of valuable bleachable tallow recovered. The system was delivered in 16 weeks after order placement. For more project details, please refer to the table below and contact us directly.
