DAF System Dissolved Air Flotation Water Treatment Machine with 3600*1700*1850mm Specification 0.1kw Skimmer and 0.55kw Coagulate Agitator

Dissolved Air Flotation (DAF) is an advanced water treatment process that effectively clarifies wastewater by removing suspended matter such as oil and solids. The system works by dissolving air in water under pressure and then releasing it at atmospheric pressure in a flotation tank, creating microbubbles that attach to suspended particles, causing them to float to the surface for removal.

The wastewater treatment process involves several key steps:

1. Wastewater enters coagulation and flocculation reaction tanks where chemicals (PAC and PAM) form flocs
2. Treated water enters the DAF tank where microbubbles attach to flocs, forming buoyant particles
3. Floating scum is removed by skimming while clean water collects at the bottom
4. Most treated water is discharged while a portion is recirculated to maintain system efficiency

• Microbubble generation for efficient particle removal
• Subsurface capture technology
• Automatic slagging controlled by liquid level
• Non-clogging release mechanism with high efficiency

Consider these key parameters when choosing a DAF system:

• Wastewater type (dairy, car washing, food processing, etc.)
• Suspended solids content (ppm or mg/L)
• Oil, grease, and fat content (ppm or mg/L)
• pH level (6-9 preferred; corrosive substances may require special materials)
• BOD and COD levels (ppm or mg/L)
