Enhanced Dissolved Air Flotation (E-DAF) System
#1 - Quality Unsurpassed
The Ecologix Enhanced DAF is a complete primary (phys/chem) treatment system. It is an incredibly versatile and efficient 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.
What is Dissolved Air Flotation?
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.
- Full movable SKID – An optional skid is now available with winch attachment.
Why Chose Ecologix for DAF Systems?
The Ecologix Enhanced DAF (E-DAF) System reduces the environmental footprint and impact when compared with other systems with similar flow rates and loading levels. For the environmentally conscious, this system will be the most efficient.
The E-DAF also facilitates high-efficiency water treatment, meaning faster separation and larger quantities that can be treated on a smaller footprint.
Battle sludge the right way. The system utilizes countercurrent scraping, the most efficient way to separate sludge from the effluent water, minimizing the chances of contamination to the effluent water. Sludge grating/thickening properties, also prevent sludge migration.
Key Features and Advantages
- 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.
