Dissolved Air Flotation (DAF) is a technology used extensively for wastewater treatment in food plants, oil & gas, mining, pulp & paper, many major industries and municipal wastewater plants. It also has a very good fit for its use in clarification of drinking water treatment, especially for difficult to flocculate, low temperature, coloured waters, and waters subject to algae blooms. DAF works extremely well for waters that have fats, oils, grease, and very fine particles.

DAF can be used by itself as a clarifier, but when used with chemicals such as a coagulant and a flocculent, it becomes a physical/chemical process. A properly functioning DAF will remove:

  • 90-95% of Total Suspended Solids (TSS)

  • 90-95% of Fats, Oils & Grease (FOG)

  • 90-95% of insoluble Biochemical Oxygen Demand (BOD)

Applications include:

  • Food and Beverage
  • Pulp & Paper
  • Automotive
  • Metal & Steel
  • Mining
  • Chemical & Petrochemical
  • Power Generation Facilities
  • Water Treatment Plants
  • Electronics
  • Wastewater Treatment Plants
  • Oil and Gas
  • Recycling Facilities
  • Solid Waste Treatment Facilities

H2FLOW also provides all ancillary treatment system devices such as screens, equalization tanks, chemical dosing, sludge dewatering, pumps, and odour control.

H2FLOW can provide a complete treatment system with all the above components, supplied by a single, experienced and reliable source. H2FLOW has been supplying DAF systems for over 20 years. We have many units available in stock, as well as pilot rental units.
