DAF — Dissolved Air Flotation

Ideal for removing fats, oil and grease from industrial waste streams, and scalable to very high flow rates.

Overview

Flotation that lifts what settling leaves behind

Dissolved air flotation introduces microscopic air bubbles into the waste stream under pressure. As the bubbles rise they attach to fats, oils, greases and low-density suspended solids, floating them to the surface where a skimmer removes them as a concentrated float layer.

It is the right answer wherever contaminants are lighter than water, or close enough to neutral buoyancy that gravity settling alone will not separate them in a sensible footprint. Ion Agua offers corrosion-resistant designs, which makes the technology equally suited to removing iron from high salt content brines.

We supply semi-automated and fully-automated pump technology systems, in capacities ranging from 100 to 5,000 gallons per minute.

Applications

Where DAF earns its place

  • Industrial waste streams — the core duty — fats, oil and grease removed from industrial effluent
  • High salt content brines — corrosion-resistant designs for iron removal from brines
  • Slaughterhouse effluent — one of the industrial sectors Ion Agua serves, with high FOG loads
  • Dairy, brewery and beverage effluent — food and beverage streams where fats and greases must come out first
  • Pre-treatment duty — conditioning the stream ahead of the biological stage
