Problem with dissolved air flotation
In your DAF prototype (separator via flotation), how is the sludge that is produced extracted? What volume of sludge is produced/1000 USG treated?
The sludge is extracted using hydraulics, i.e. closing off the float water valve causes a rise in the DAF tank level, and the sludge spills over. We treat 105 USG/min and program a sludge extraction every 5 h for a discharged volume of about 790 USG.
