Ecopro 5m3/H Capacity DAF System with 0.55kw Air Compressor and 3kw Dissolved Pump Power for Wastewater Treatment

The Dissolved Air Flotation (DAF) system is an advanced water treatment process designed to clarify wastewater by effectively removing suspended matter such as oil and solids.

This removal is achieved by dissolving air in the water or wastewater under pressure and then releasing it at atmospheric pressure in a flotation tank. The released air forms microbubbles that adhere to suspended particles, causing them to float to the surface where they can be removed by a skimming device.

1. Wastewater enters RT1 (coagulation reaction tank) and RT2 (flocculation reaction tank) from the equalization tank through the lift pump, where it coagulates with PAC and flocculates with PAM respectively to form flocs.

2. The wastewater and dissolved water then enter the reaction zone of the DAF tank, where microbubbles and flocs mix and adhere to form solid particles with density less than water.

3. These particles float to the surface of the DAF tank where scum is scraped to the slag tank by buoyancy action.

4. Clean water is collected in the collection tank through water collecting pipes, with most water being discharged (or sent to next process) while a small portion is recirculated to form dissolved water.

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

• Municipal sewage treatment
• Slaughter house wastewater

Consider these factors when selecting a DAF system:

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