Product Description
Liquid-solid separation technology and the related equipment are the essential factor to drainage treatment proces. Dissolved air flotation is one of the most effective methods for removing the tiny pollutants from the waste water. Superficial DAF System, also called cirlar shallow DAF system. It's the main treatment device in water purification system.
Working Theory
Flotation separation technology means that the air and water are dissolved into the water to the greatest extent under a certain pressure condition, anid strive to be in a saturated state, and then the formed pressure dissolved gas water is released through decompression to produce a large amount offine particles. The air bubbles are in full contact with the suspended flocs in the water, so that the suspended flocs in the water adhere to the micro-bubbles, float to the water surface with the bubbles, form scum and scrape the scum, thereby purifying the water. Using the "shallow layer theory" and "zero speed" principle, through careful design, it integrates agglomeration, air flotation, slag skimming, sedimentation, and mud scraping. It is a high-eficienicy equipment for water purification treatment.
Superficial DAF in paper mil is designed according to Zero Speed Principle and Shallow Pool Theory. First of all, the depth of the tank is just 750-950mm. The influence from the equalization tank is pumped into the circular DAF tank after coagulation and flocculation. The rotating system with distributor, scum skimmer and collecting plipes is drivenfor anti- clockwise rotation while the influence comes at clockwise direction. In this way, the water speed in the tank is zero relatively. The micro bubbles generated by GFA dissolved air system would mix the flocculation and float onto the surface. The depth of the tank is just 750-950mm, which can separate liquid and solids effectively. The scum is scrapped by the rotating skimmer into the central scum slot and falls down the sludge tank downstairs. The clean water is collected and flow into the clean tank. Electric cabinet control all the elements and it just take 3-5 minutes to purify the waste water.
