Dissolved Air Flotation

 

Working Principle

Filtrate to be clarified is mixed with very small air bubbles, a flocculent, and in some cases a coagulant. The chemicals enable the collection of nearly all suspended solids into flocs. The presence of air bubbles in the flocs provides them with a density below one and enables them to float to the surface.

 

The separation plates or cones (lamella) provide a high separation surface resulting in excellent water quality and significantly reduced chemical consumption.

 

Applications

 

  • Mill effluent
  • Fiber recovery (Saveall)
  • Deinking gray water
  • Micro stickies and wax removal
  • Filtrate polishing

 

Features and Benefits

 

Operation

  • High TSS capture rate (generally over 95%)
  • High sludge consistency up to 12%
  • High water yield up to 98%
  • Easily handles upstream variations in flow rate and feed concentration
  • Modular design allows for future capacity increases
  • Significant polymer savings
  • Extremely reliable air mixing system allows optimal calibration of the bubble size
  • No plugging risks

 

Installation

  • Low installation costs due to the modular and pre-assembled construction
  • Small footprint
  • Little or no field erection: unload, position and connect

 

Operating Cost Advantages

  • Low polymer consumption
  • Minimal operator attention
  • Stainless steel and corrosion-proof construction
  • Low maintenance
