Dissolved Air Flotation (DAF) Air-to-Solids Ratio Calculator
Determine Air-to-Solids ($A/S$) ratio, saturator vessel operating pressure, recycle stream pumping rate, and hydraulic surface rise rate for industrial DAF clarifiers.
Influent Flow & Suspended Solids
Includes FOG (Fats, Oils, Grease)
Typically 4.0 - 6.0 bar gauge
Standard: 20% to 50% for DAF
