Industrial Wastewater Oil Water Separator Micro Bubble Generator DAF Dissolved Air Flotation
The DAF combines Ph Control, Coagulation, Flocculation and Flotation, all in one unit. The Patented SYSDAF technology does not require compressed air or bottom scraping. Dissolved air is provided to the system all along the bottom of the flotation tank and this ensures very efficient operation, maximum removal of pollutants and no sedimentation.
The final stage of chemical treatment includes the separation of solids and flocs from the water. Depending upon the characteristics of the solids/flocs, sludge and clean water can be separated using:
Slant Plate Clarifiers use gravity settlings, the most energy efficient solids/water separation technique. Slant plates are used to decrease the distance a particle has to fall before it hits a surface. The flow rate of the clarifier is based on a number of factors, including particle density, surface area, fall rate, loading and temperature.
Dissolved Air Flotation (DAF) are incorporated when the sludge is less dense than water, or is neutrally buoyant. DAF uses billions of micro-bubbles that attach themselves to the flocs and carry them to the surface. These bubbles, known as “whitewater”, are removed by a mechanical skimmer within the DAF unit that skims away floating sludge.
