DAF wastewater treatment

The food and beverage industry requires total removal of suspended solids (TSS) biochemical oxygen demand (BOD5), and oils and greases (O&G). They need an efficient solution, highly resilient to process alterations during wastewater treatment with minimal operator intervention.

An Efficient Direct Air Flotation Treatment Method

The Global Water & Energy’s SUPERFLOT™ system uses dissolved air flotation method which forces floating contaminants to the surface of wastewater, using a curtain of fine air bubbles injected under negative pressure. The air bubbles cling to the suspended particles which float to the surface. These rise to the surface when the atmospheric pressure returns carrying solids, fat, oil and grease. These are then scraped off and disposed. They are then removed by a surface skimmer into an internal hopper for further handling. There are many applications suited to this process. These include livestock processing, laundries and textiles, pulp and paper manufacture, plastics recycling, and food production to mention a few. The SUPERFLOT system can also operate in tertiary mode with combined coagulant / flocculent dosing. Wastewater cleansed this way may be discharged into surface water subject to local regulations.


  • Removes solids, fats, oils, and greases from wastewater
  • Suitable for separating sludge following aerobic treatments
  • Zero-chemical low energy system that is environmentally friendly
  • Smaller footprint in comparison with gravity clarification
  • Sludge disposal costs are reduced due to a higher solids concentration in the separated sludge

Global Water & Energy is specialized in industrial wastewater treatment and waste-to-energy solutions.
