Every SAF™ bubble is a working bubble- click here to go back to Solutions
Ryan Process can supply you with a wide range of dissolved air floatation systems for industrial and municipal wastewater, 
water and groundwater


Each coated suspended bubble binds electrostatically with polymer molecules of opposite charge on the flocculated solids, forming a much stronger bond than is possible with a plain air bubble. Much less air is necessary to float solids with SAF™. Experience with many wastewaters has shown that with SAF™, an air-to-solids percentage (weight to weight) of 1% is sufficient for treatment for solids of practically any concentration, compared with a minimum requirement of 2% for competing technologies, rising to as much as 15% for applications with suspended solids concentrations 2,000 mg/L and higher. This translates directly into a better and better footprint advantage for SAF™ for applications with higher solids concentrations.

Suspended Air™ Emulsion generators operate at a modest 20 psi pressure. A DAF pressurizes the recycle flow to 60 - 80 psi.

Eleven models with capacities from 26 G.P.M. to 1000 G.P.M. All models can be piped in series for unlimited capacity.
