Dissolved Air Flotation

Dissolved Air Flotation (DAF) system is a very effective clarifier system where solid or liquid particles are separated from a liquid phase. Separation is brought by introducing fine bubbles into the liquid phase. The bubbles attached to particulate matter, and the buoyant force of combined particle and gas bubbles is great enough to cause the particle to rise to the surface. Particles that have higher density than the liquid can thus be made to rise. The rising of particles with lower density than the liquid can also be facilitated i.e. oil suspension in water. Once particles have been floated to the surface, they can be collected by skimming operation.

We can offer you high efficiency floatation system that will reduce your operational cost and more benefits to achieve your water quality demand!

Benefits of DAF system:

  • Reduced operational cost – thanks to the microbubbles generator system that makes the adherence of suspended solids to bubbles is easier and more intensive. Microbubbles also serve to remove light particles that difficult to settle
    • Reduced chemical costs
    • Reduced foot-print (great compactness) by additional plate pack technology that can handle higher water and solid loading capacity
    • Produced thicker sludge
    • High quality of treated water
    • Easy automation
    • Rapid start-up and flexibility in Go and Stop mode

Aplicattions :


  • Water and Wastewater Clarification (Primary and Tertiary Treatment)
  • Activated Sludge Thickening
  • Membrane Pre-treatment
  • Filter Backwash Recovery
  • Oil and Grease Removal
  • Algae Removal
  • Meat processing wastewater
  • Dairy Processing
