Product Description

 HOME/ABOUT US
Garbage Cans Process Wastewater Daf Dissolved Air Flotation Plant
We apply our experience and skill to design solutions for municipal, industrial, and minerals clients. We employ a wide variety of liquid/solids separation and biological treatment technologies. 
EVU Industries manufactures complete dissolved air flotation (DAF) clarifier systems. Remove FOG, TSS, BOD, COD, and pollutants from your wastewater. Review our DAF clarifiers below or contact us for more information.
Dissolved air flotation (DAF) for industrial wastewater treatment is a water clarification process that uses micro-bubbles to remove impurities and solids. The process is ideal for removing light impurities and solids that tend to float and suspend in liquid.

WHY WE USE DAF?
Garbage Cans Process Wastewater Daf Dissolved Air Flotation Plant

DAF systems separate solids, oils, greases, and other impurities from water. The clean water can be reused or discharged. DAF is used for a variety of goals, including:

  • Treatment to meet discharge regulations
  • TSS Removal
  • Water recovery and reuse
  • Pretreatment to reduce loading on downstream biological treatment systems
  • COD & BOD Removal
  • Polishing of biologically treated effluent
  • Thickening of slurry
  • Pretreatment for desalination plants utilizing reverse osmosis
HOW DOES DAF WORK?

DAF uses micro air bubbles (30-50 micron) that attach to impurities and flocculated particles and float them to the water's surface. Then a skimming system removes the sludge to a desludging trough, and clean water is recovered.

The clean water can be reused for process or discharged, and some of it is recycled back to the DAF process.

DAF CLARIFICATION STEPS
Garbage Cans Process Wastewater Daf Dissolved Air Flotation Plant

First, clean water needs to be accessible for a DAF system to startup. Clean water is necessary because DAF systems pressurize the water and mix it with pressurized air. Under pressure, the air dissolves, and when de-pressured, micro-bubbles form. The micro-bubbles are necessary to the cleaning process.

So, the first step is to fill the DAF system with clean water. If you fill the DAF unit with wastewater, you'll likely discharge wastewater for a long time. Plus, you risk damaging the recirculation pump and air saturation system.

Once clean water is in the system, a recirculation pump pulls some of the clarified water to a pressurization-saturation system. Next, the water is pressurized by a pump and mixed with pressurized air. Under this pressure, the air dissolves in the water.

Now the saturated water flows under pressure to the clarification tank. In the clarification tank, the pressure releases, and micro-bubbles form.

The micro-bubbles attach to the impurities from the incoming wastewater stream and pull them to the top. When sediment rises, a floating sludge blanket forms on top of the water within the clarifier.

Next, a skimming system gently removes the sludge from the top of the water. You'll see the skimmers pull sludge off the top and drop it into a desludging trough.

Finally, clean water is recovered through a supernatant system. Basically, the clean water comes out of a discharge point below the floating sludge and above the settled sludge.

 


DO DAF SYSTEMS MANAGE SLUDGE?

Most systems account for and manage settled sludge. DAF systems are ideal for wastewater streams that contain solids that float and settle.

In general, you'll find most manufacturers include a sediment compartment or basin with a sludge extraction system



CHEMICAL TREATREMNT WITH DAF

Coagulants and flocculants are regularly used to pretreat wastewater before it enters a DAF system.

Like other wastewater treatment methods, a DAF system can benefit from particles that bind due to flocculants. The skimming systems can remove a thicker, more dewatered sludge that may need little to no further dewatering.

Dissolved Air Flotation (DAF) has been known as one of the most effective and robust ways to remove suspended solids (TSS), biochemical oxygen demand (BOD5), fats, oils, and grease (FOG), phosphorus (P) or nutrients from industrial wastewaters. In response to variations in industrial activity, variations in wastewater and water streams, and the ever-demanding customer requirements, EVU Industries has engineered one of the most intelligent and reliable Dissolved Air Flotation systems available.

When selecting a DAF system for your wastewater treatment plant or resource recovery installation, customers typically choose the DAF supplier and equipment based on their industrial experience, quality, performance guarantees, and reliability. As a result, EVU has provided more than 3000 Dissolved Air Flotation systems worldwide in various industries, including; food and beverage production, dairy processing, meat processing, agricultural, oil and gas, and municipal markets, to name a few.

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

Garbage Cans Process Wastewater Daf Dissolved Air Flotation Plant
Dissolved Air Flotation is based on a physical/chemical process, where air is injected into the water stream and with chemical assistance causes the particles/flocks to float to the surface. This floating sludge layer is then automatically and continuously removed by a scraper mechanism. The DAF system will produce a treated effluent virtually free of TSS, FOG, and removes a large portion of the BOD.
 

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

Garbage Cans Process Wastewater Daf Dissolved Air Flotation Plant
  • 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?

The Dissolved Air Flotation system has proven very effective in industrial wastewater pretreatment and has been used in various water, wastewater, and desalination applications. To maximize the removal of suspended solids and colloidal particles and substances, a flocculator with chemical dosing can be added in front of the DAF. This ensures the polluted water is chemically pretreated before entering the DAF unit, thereby providing maximum removal rates (TSS and FOG in excess of 95% is common).
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
