Dissolved Air Flotation (DAF)
Dissolved Air Flotation (DAF) is an efficient wastewater treatment system designed to remove oil, grease, suspended solids, and emulsified particles, while significantly reducing COD. By generating fine air bubbles, contaminants are floated to the surface and removed effectively, making DAF an ideal solution for industrial and municipal wastewater treatment.
Its robust design, high treatment efficiency, and wide industrial applicability make the DAF unit a reliable choice for both pre‑treatment and primary treatment processes.
Advantages
- Increases the overall efficiency of the wastewater treatment system
- Reduces operation and maintenance costs
- Improves the performance of downstream treatment units (biological and filtration systems)
- Requires less footprint compared to conventional treatment methods
- Easy operation and simple maintenance
- Suitable for a wide range of industrial applications
Applications
- Effective removal of oil, grease, and suspended solids (free and emulsified)
- Significant reduction of COD and overall pollution load
- Ability to separate particles with density close to water
- Production of thick and highly concentrated sludge
- Cylindrical design with high structural strength and long service life
- Resistant to hydraulic and organic shock loads
- Prevents clogging of downstream pipes and equipment
- Modular design with the possibility of future capacity expansion
