Enhanced Dissolved Air Flotation (E-DAF) System

The Ecologix Enhanced DAF is a complete primary (phys/chem) treatment system. It is an incredibly versatile and efficient combined chemical precipitation and physical separation system. The E-DAF combines several proven technologies such as DAF (Dissolved Air Flotation), ACE (Air Charged Entrainment) and DGF (Dissolved Gas Flotation), into a single platform. Our E Series Dissolved Air Flotation (DAF) systems are the industry standard for efficient removal of Fats, Oils and Grease (FOG), Total Suspended Solids (TSS) and Biochemical Oxygen Demand (BOD) from a wide variety of wastewater streams.

Key Features and Advantages

  • Reduced footprint – Compared to any comparable system with similar flow rate/loading levels.
  • High efficiency – Utilizes inclined settling tubes for increased surface area and faster separation.
  • Air scouring – for automatic tube cleaning.
  • Whitewater pumps – robust pumps in combination with saturation tanks provide industry leading reliability and low maintenance whitewater (dissolved air).
  • Countercurrent scraping – for the most efficient separation of sludge from the effluent water. This also allows for more free water to decant prior to sludge removal.
  • Sludge grating/thickening – Prevents sludge migration and thickens it.
  • Fewer moving parts – no need for bottom auger and motor.
  • DAF (Dissolved Air Flotation) and ACE (Air Charged Entrainment) combined into one – attached and entrained air for higher separation efficiencies.
  • Upgradable to a full ITS (Integrated Treatment System) – including upgraded control panel, chemical feed pumps, polymer make down system, flocculation tubes, pre-wired and pretested as a complete wastewater treatment system.
  • Easily converted to DGF (Dissolved Gas Flotation) for refineries and offshore platforms.
  • Built from high corrosion resistant material such as 304SS or 316SS (upon request)
  • Integrated walking mezzanine with stairs.
  • Optional post-filtration filters.
  • Optional dewatering system.
