CAF Cavitation Air Flotation Machine: Industrial Wastewater Treatment Solution, ISO 9001 & CE Certified

Product Description

What is DAF?

Dissolved air flotation is a water treatment process that clarifies wastewater by removal of suspended solids, oils, greases, BOD,
COD, and metals. This is achieved by dissolving air in the wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank. The released air forms tiny bubbles which adhere to the suspended matter causing it to float to the surface of the water where it can then be removed by a skimming device, ready to dewater for proper disposal. To improve solids
removal coagulant/flocculants are added to coax suspended solids and colloidal particles into clumping together.

FAQ

1. What is a DAF machine used for?
A DAF machine is used for water treatment, removing suspended solids, oils, and organic matter from wastewater. It works by releasing tiny air bubbles that attach to particles, making them float to the surface for removal.

2. How does a DAF machine differ from sedimentation?
DAF: Uses air bubbles to float particles up (for low-density solids like oils, fats, or flocculated matter).
Sedimentation: Relies on gravity to settle heavy particles down (suitable for high-density solids).

3. What are typical applications of DAF machines?
Industrial wastewater treatment (e.g., food & beverage, petroleum, textiles).
Municipal sewage treatment.
Oil-water separation.
Pre-treatment for reverse osmosis systems.

4. How to maintain a DAF machine?

Regularly clean the flotation tank and skimmer.
Check dissolved air pressure and nozzle blockages.
Inspect pumps, valves, and filters for wear.
Monitor chemical dosing systems (e.g., coagulants/flocculants).

5. What causes low removal efficiency in DAF?
Inadequate air dissolution (check pressure or compressor issues).
Improper chemical dosing (adjust coagulant/flocculant ratios).
High influent turbidity or temperature.
Clogged nozzles or damaged diffusers.

6. Can DAF handle high TSS (Total Suspended Solids) wastewater?
Yes, but pre-treatment (e.g., screening or pre-flocculation) may be needed for extremely high TSS levels to prevent nozzle blockages and optimize performance.

7. What is the typical energy consumption of a DAF machine?
Energy use varies by size, but a standard DAF system consumes ~0.3–0.8 kWh/m³ of wastewater, mainly for pumps and the air compressor.

8. How long does a DAF machine last?
With proper maintenance, DAF machines can last 10–15 years. Stainless steel components extend lifespan in corrosive environments.

9. Can DAF be used for drinking water treatment?
Yes, DAF is effective for removing algae, color, and organic matter in drinking water sources, often replacing traditional sedimentation tanks.

10. What’s the installation process for a DAF machine?
Level the foundation and connect pipes (inlet, outlet, sludge discharge).
Install the air dissolution system, tank, and skimmer.
Connect electrical components and control panels.
Commissioning includes water testing and parameter optimization.
