Dissolved Air Flotation Systems 
  

Applications

Dissolved air flotation (DAF) is well-suited for liquid-solid separation in many industries, as well as for separation of free oils and greases. Applications include the pretreatment of a variety of waste streams, including those from:

  • Meat and poultry processing plants

  • Bakeries

  • Confectionery plants

  • Laundry facilities

  • Dairy processors

  • Metal fabricators

  • Pulp and paper mills

  • Chemical plants

  • Textile plants

  • Railroad yards

  • Vegetable oil processors

  • Rendering plants

  • Snack food processors

  • Fruit and vegetable processors and canneries

  • Pet food processors

  • Biological treatment facilities (clarification, WAS thickening, algae removal)

In addition, ETS DAF systems can in many cases provide for the re-use of treated effluent in many ways, such as cooling water, polymer makeup water, and wash water.
