Dissolved Air Flotation (DAF) is a widely used wastewater pretreatment technology for removing suspended solids, oil, and grease. Integrating DAF with other processes can significantly enhance treatment performance, lower operational costs, and meet strict discharge standards.
What Is Dissolved Air Flotation and How Does It Work?
The DAF system injects microbubbles into wastewater. These bubbles attach to suspended particles and lift them to the surface for removal. DAF is effective in:
- Primary clarification
- Pre-treatment for biological and chemical processes
- Industrial wastewater treatment (food, petrochemical, textile, etc.)
By reducing suspended solids and oil early in the process, DAF units optimize downstream performance.
Integrating DAF with Biological Treatment Processes
DAF systems are commonly combined with biological processes such as:
- Activated Sludge Process
- Biological Contact Oxidation
- Membrane Bioreactor (MBR)
Benefits include:
- Reduced organic and solid load to biological units
- Improved microbial efficiency
- Stable and cost-effective operation

Integrating DAF with Chemical Treatment Processes
Dissolved Air Flotation also enhances advanced oxidation and chemical treatment methods such as:
- Fenton Reaction (Fe²⁺ + H₂O₂)
- Hydrogen Peroxide Oxidation
- Coagulation & Flocculation
DAF provides an ideal platform for mixing, air contact, and solids removal—improving reaction efficiency and reducing chemical dosage.

Why Choose DAF for Your Wastewater Treatment System?
Dissolved Air Flotation offers flexibility, high efficiency, and easy integration. When paired with biological or chemical processes, it helps meet even the most stringent environmental standards.
DAF is ideal for industries such as:
- Food & Beverage
- Textiles & Dyeing
- Oil & Gas
- Municipal Water Treatment
To ensure optimal system design, consult experienced DAF system manufacturers who can tailor solutions based on your influent characteristics and discharge goals.
