Vertical dissolved air flotation system works according to the same principle as others, just the difference in structure. Vertical dissolved air flotation system is equipped with cylindrical tank, central distribution and peripheral outflow. It's better to separate the sludge and water at the separation zone, and it's widely used in WWTP -- Waste Water Treatment Plant for small capacity less than 50m3/h.
Features
Less land occupation
High surface load
Simple operation and easy maintenance
Working Theory
The dissolved air water produced by GFA system is pumped into the air releaser by reducing the pressure. 15-30um micro bubbles from the air releaser would adhere to the suspended solids make them lighter than water, then the solids combined with micro bubbles can float onto the surface to form a scum layer that would be scrapped by the skimmer system into the sludge tank. The lower clean water flows into the clean water tank. At least 30% of the clean water is recycled for GFA system while other is discharged or pumped to next process.
Application
Electroplating industry Tannery industry Printing and dyeing industry Slaughtering and breeding industry
