Dissolved Air Flotation DAF System with Microbubbles Generating Subsurface Capture and Automatic Slagging for Wastewater Treatment

The Dissolved Air Flotation system is a water treatment process that clarifies wastewaters by removing suspended matter such as oil or solids. The system works by dissolving air in the water under pressure and then releasing it at atmospheric pressure in a flotation tank, creating microbubbles that adhere to suspended particles and float them to the surface for removal.

The wastewater treatment process follows these steps:

• Wastewater enters coagulation and flocculation reaction tanks where it forms flocs with PAC and PAM chemicals
• The treated water and dissolved air enter the DAF tank's reaction zone
• Microbubbles adhere to flocs, forming particles that float to the surface
• Surface scum is scraped into a slag tank while clean water is collected below
• Most water is discharged while a portion is recirculated to create dissolved water

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

Our DAF systems are suitable for various industries including:

• Municipal sewage treatment
• Slaughter house wastewater
• Metallurgical industry wastewater
• Spraying and painting operations
• Printing and dyeing processes
• Metal-processing facilities
• Mining and stone processing
• Electronic component manufacturing

To select the appropriate DAF system model, please consider these factors:

• Wastewater type (dairy, car wash, food processing, etc.)
• Suspended solids content (ppm or mg/L)
• Oil, grease, and fat content (ppm or mg/L)
• pH level (6-9 preferred)
• BOD and COD levels (ppm or mg/L)
