Dissolved Air Flotation System, DAF Wastewater Treatment Equipment

If you are looking for a machine to treat sewage with a large amount of suspended matter or sewage with high oil content, such as to treat micro-polymers such as algae in water, then the dissolved air flotation system produced by BETTER EPT is your best choice. The scum produced after treatment can be automatically discharged, and the solid matter in the discharged scum is up to 30-100g/L.

Characteristics

  • The reflux ratio of the dissolved air flotation system is high and the quality of the effluent is good.
  • The dissolved air flotation system will aerate the water to remove the surfactant and odor in the sewage effectively during the treatment process. Meanwhile, the aeration increases dissolved oxygen in the water, which provides favorable conditions for the subsequent treatment.

Applications

  • Product recovery and reuse
  • Pretreatment to meet sewer discharge limits
  • Pretreatment to reduce loading on downstream biological systems
  • Polishing of biological treatment effluent
  • Removing silt, oil, grease, fats and suspended solids from industrial water.

Industries served include glass manufacturing, paper mills, food and dairy processing, meat, fish, and poultry slaughterhouses, and waste vegetable oil recycling.

Characteristics

  • Design Treatment Capacity: 5–300 m³/h.
  • High-Rate Clarifier: Suitable for high suspended solids (SS) water with light particles, oil, and colloids.
  • Fully Manufactured in Factory: 100% factory-assembled, with no need for secondary welding. Assembly requires three hours and two personnel.
  • Indoor or Outdoor Layout: Suitable for both layouts; environmental temperature must be above 0°C.
  • Automatic & Continuous Operation Compatibility
  • Design Life:
    Carbon Steel Material: >10 years
    304 Stainless Steel Material: >20 years
    316 Stainless Steel Material: >25 years
Advantages
  • High Scraping Speed: 2–3 times faster than conventional designs, with safe operation due to the fully reversible and closed scraper.
  • High Hydraulic Load, Low Footprint: Horizontal plates in the separation zone enable more effective separation and optimized hydraulic flow.
  • Improved Outlet Water Quality: W-shaped sludge sedimentation hopper enhances water clarity.
  • Reduced Chemical Consumption: Reverse scraping design improves re-flocculation performance, minimizing chemical usage.
  • Efficient Scum Collection: No blind angles in the scum collection chamber.

Details

Dissolved Air Flotation System

The chain and sprocket wheel of the scraper device
The chain and sprocket wheel of the sludge scraper of the dissolved air flotation system produced by BETTER EPT are made of nylon material, which gives the chain and sprocket wheel good mechanical strength, wear resistance and shock absorption. It can also effectively separate the solid and the liquid in the scrum area.

Dissolved Air Flotation System

Releaser
The releaser is one of the most important components of the dissolved air flotation system, the function of which is to release bubbles in the sewage and with the bubbles adhering to the pollutants, the pollutants in the sewage will float to the surface under the reaction of buoyancy. The releaser produced by BETTER EPT is made of stainless steel material, so it’s more corrosion resistant. And with the countless micro bubbles released by the releaser, the removal rate of suspended matters is effectively improved.

Working Principle

By releasing a large number of microbubbles in the sewage and with the bubbles adhering to the pollutants, the pollutants in the sewage will float to the surface under the reaction of buoyancy. And after the sludge is discharged by float removal system, the solid and the liquid are effectively separated.
