What is Dissolved Air Flotation, and how does Dissolved Air Flotation work?

What are the EVU Industries Intelligent Dissolved Air Flotation benefits and features?

- Maximum TSS, FOG, and BOD removal efficiency and reduced energy consumption with the EVU patented i-AERATION system.
- Reduced installation time as EVU DAF units are shipped as prefabricated units with onboard mounted equipment. Additionally, compact DAF units can be installed in containers or on a box frame or skid.
- Suitable for several polluted water types and applications based on the EVU Dissolved Air Flotation material execution.
- Operational flexibility and reduced sludge disposal with Nijhuis smart level control and sludge scraper system.
- Reduced footprint with EVU Plate Pack Technology.
- High solids loading with EVU Open Flotation Technology.
Why Dissolved Air Flotation?
Depending on the application and the client's requirements, a DAF system can be fabricated in concrete construction or, for very large flows, in stainless steel. The most common DAF treatment applications include:
- Pretreatment for TSS and FOG removal from Industrial wastewater
- Fats, oils, and grease resource recovery
- Drinking water intake solids removal
- Water treatment pre-treatment to remove solids and algae blooms
- Wastewater biological treatment as activated or anaerobic sludge flotation
- Wastewater tertiary treatment to remove phosphorus and nutrients
- Pretreatment for Desalination systems
- Process water production
