E Series Dissolved Air Flotation (DAF) System

The Ecologix Emerald (E) Series DAF is a complete primary (phys/chem) treatment system. It is an incredibly versatile and efficient combined chemical precipitation and physical separation system. The Emerald 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.
  • 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)
  • 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.
  • Integrated walking mezzanine with stairs.
  • Optional post-filtration filters.
  • Optional dewatering system.

DAF System Applications

The following is a sampling of applications that we have successfully deployed DAf systems.

Air Charged Entrainment (ACE) Explained

To optimize the floatation process and reduce the required footprint, Ecologix has invented a process called ACE (Air Charged Entrainment) by which the air bubbles are embedded inside the sludge. This creates a more efficient separation process as the air/gas entrainment facilitates faster particle floatation and consequently reduces the system's footprint and cost.

The ACE system further enhances our DAF system by attaching millions of small air bubbles are then attached to the large particles formed during the flocculation process. This enhancement provides greater capture of the sludge that is then lifted to the surface of water.
