EVU DISSOLVED AIR FLOTATION UNIT

 

DISSOLVED AIR FLOTATION UNIT BRIEFING
 

Dissolved Air Flotation is a proven and effective physical/chemical technology for treating a variety of wastewater streams

DAF systems are designed to remove total suspended solids (TSS), biochemical oxygen demand (BOD), and oils and greases (O&G) from a wastewater stream. Contaminants are removed using a dissolved air-in-water solution produced by injecting air under pressure into a recycle stream of clarified DAF effluent. This recycle stream is then combined and mixed with incoming wastewater in an internal contact chamber where the dissolved air comes out of the solution in the form of micron-sized bubbles that attach to the contaminants. The bubbles and contaminants rise to the surface and form a floating bed of material that is removed by a surface skimmer into an internal hopper for further handling.

 

 

DISSOLVED AIR FLOTATION UNIT GOALS

DAF systems are commonly used for the removal of oils & greases and suspended solids to meet a variety of treatment goals including:

• Product recovery and reuse
• Pretreatment to meet sewer discharge limits
• Pretreatment to reduce loading on downstream biological treatment systems
• Polishing of biological treatment effluent
• Thickening of biosolids

DISSOLVED AIR FLOTATION UNIT ADVANTAGES OVER TRADITIONAL METHOD

Some of the advantages over traditional, gravity clarification include:

• Smaller footprint and more rapid implementation
• Higher sludge solids content (4%TS vs. 1%TS) resulting in a much lower sludge volume
• Ability to handle bulking solids that tend to float
• More reliable effluent quality

DISSOLVED AIR FLOTATION UNIT FEATURES

EVU provide unique standard features including:
1 Complete, skid-mounted design for ease of installation
2 Rectangular profile for maximum space utilization
3 Superior performance without the use of plate-pack that can foul or collapse
4 Quality drive and pump components for long-term reliability
5 Large, internal float hopper eliminates the need for an external float tank
6 Available in 304 or 316 SST tank construction
7 Several controls platforms (Motor Starter, Relay Logic,
Integrated Controller,  PLC/HMI)
