Industry Wastewater Treatment Plant With Sludge Scraper Equipment DAF System


Air flotation technology of DAF dissolved air flotation plays an important role in solid-liquid


separation (Simultaneously reduce COD, BOD, chroma, etc). Firstly, mix flocculating agent


into raw water and stir thoroughly. After the effective retention time (lab determines the time,


dosage and flocculation effect), the raw water enters into the contact zone where microscopic


air bubbles adhere to the floc and then flows into the separation zone. Under the buoyancy


effects, the tiny bubbles float the flocs to the surface, forming a sludge blanket. A skimming


device removes the sludge into the sludge hopper. Then the lower clarified water flows into


the clean-water reservoir through the collecting pipe. Some of water are recycled to the


flotation tank for the air dissolving system, while others will be discharged.





1. Flow rate of one set: 1-300 m³/h.

2. Recycle flow dissolved air flotation.

3. High efficiency pressurization system providing high quantity dissolved-air water to create


large quantities of small bubbles.

4. Custom design on different dissolved air flotation equipment and recycle flow ratio


according to the type of wastewater and treatment requirement to achieve target removal


effect and stability.

5. Adjustable stainless steel chain type skimmer to suit the different quantity of sludge.

6. Integrated coagulation tank and or flocculation tank and cleaning water tank(as optional)is

available to save the space and cost.

7. Automatic and remote controllable.

8. Material of construction: carbon steel epoxy painted, carbon steel FRP line, stainless steel



Key DAF features


1. Air dissolving pump and suction water pump suction, pressure in mixing, dissolving high


efficiency, fine bubbles is less than or equal to 30um.

2. Low pressure operation, dissolved air efficiency of up to 99%, the release rate of up to 99%.

3. The effective adsorption of micro bubbles and suspended particles increased the removal efficiency of SS.

4. Dissolved gas water solution efficiency of 80-100%, 3 times higher than the traditional


dissolved air flotation efficiency.

5. Pressure - volume curve is smooth, easy to realize automatic control, easy to operate, easy


to maintain, low noise.
