Is there an easy test to tell if a DAF is right for an application?

For a DAF clarifier, subnatant clarification is the goal. Hydraulic loading governs and solids loading is usually not a problem. With high volumes of dilute solids, a higher air/solids ratio is used and a recycle rate of 10-30% of the forward flow is selected depending on how “easy to float” the material is.
