A simplified method for assessing the saturation efficiency at full-scale dissolved air flotation plants

This paper proposes a simplified yet comprehensive method for measuring the efficiency of air saturation systems used in dissolved air notation. It is based on a review of methods suggested by other researchers in this field, but several improvements to existing methods are made. A saturation air co mposition different than that of atmospheric air and incomplete precipitati on in the measuring unit after pressure release are taken into consideratio n. The developed measurement and calculation procedure provide engineers an d operators alike with an easy tool to assess the saturation efficiency of their system at full-scale DAF plants as well as at pilot and laboratory sc ale plants.
