Dissolved Air Flotation (DAF) operates by saturating water with dissolved air under high pressure. The water is then released into the flotation tank, where the air comes out of solution in the form of fine bubbles. These bubbles attach to suspended solids, oils, and other contaminants, causing them to rise to the surface. The floatation process allows for easy removal of these impurities as sludge or scum. This highly efficient separation process is particularly effective for removing oil, grease, fats, and solid waste from industrial wastewater.
Key parameters and typical removal efficiencies include:
- Suspended Solids: Removal efficiency up to 98%, including fine particulates, colloidal materials, and organic matter.
- Oil & Grease: Removes up to 95% of oils and greases, making it ideal for food processing, petrochemical, and manufacturing industries.
- COD & BOD: Reduces Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD) by up to 80%, improving water quality and reducing treatment costs.
- Sludge Removal: Efficient separation of sludge and scum, ensuring minimal residual solids in the effluent.
- pH Range: Effective in a wide range of pH conditions, from acidic to slightly alkaline waters, ensuring versatility across industries.
Benefits of DAF Systems
- High Efficiency: Efficiently removes fine particles, oils, and suspended solids, offering high-quality water treatment with minimal sludge generation.
- Cost-Effective: Reduces the need for expensive chemical treatments and allows for easy separation of contaminants, reducing operational and disposal costs.
- Compact Design: Space-saving systems that can handle varying water flow rates without requiring extensive infrastructure.
- Environmentally Friendly: Helps industries comply with stringent wastewater discharge regulations by reducing environmental pollutants and improving water quality.
- Minimal Chemical Usage: Reduces the need for flocculants and coagulants, making it an eco-friendly option for wastewater treatment.
