- Flotation: These bubbles attach to suspended solids, oils, and grease, making them buoyant and rise to the surface.
- Skimming: A skimming mechanism collects the buoyant solids, leaving clarified water in the tank.
Mini-Maxi Aspects of DAF:
- Compact Design: DAF units are often modular, allowing for flexible sizing and installation in limited spaces. This minimizes the land footprint required for the treatment process.
- Energy Efficiency: Advanced air injection systems, like those used by Tenco Hydro, optimize air dissolution, minimizing energy consumption and lowering operational costs.
- High-Quality Treatment: DAF units efficiently remove a wide range of contaminants, producing clean water for drinking, industrial, and other applications.
Advantages of Using DAF:
- Reduced Footprint: Minimizes land usage and construction requirements.
- Lower Operational Costs: Reduced energy consumption and minimal maintenance translate to cost savings.
