Introduction
High speed flotation water treatment is a type of air flotation equipment that passes in or generates a large number of fine bubbles in the water, so that the air is attached to the suspended particles in the form of highly dispersed tiny bubbles, resulting in a state where the density is less than that of water. The principle of buoyancy makes it float on the water surface, Water treatment equipment that realizes solid-liquid separation.
Working Principle
After the dosing reaction, the sewage enters the air flotation mixing zone, mixes and contacts with the released dissolved air, so that the flocs adhere to the fine bubbles, and the flocs float to the water surface under the action of air buoyancy to form scum, and the lower layer of clear water After flowing into the clean water tank through the water collector, a part of the reflux is used as dissolved air, and the remaining clean water flows out through the overflow. After the scum on the water surface of the air flotation tank reaches a certain thickness, it is scraped into the air flotation sludge tank by the slag scraper and discharged.
The air flotation machine is suitable for:
1. Papermaking white water pulp recovery and clean water reuse
2. Removal of various heavy metal ions
3. Separation of refining wastewater and oil pollution
4. Removal of impurities in tanning wastewater
5. Removal of chroma and impurities in textile printing and dyeing wastewater
6. Solid-liquid separation of sludge and membrane after various treatments
7. Sludge thickening
8. Sewage from slaughter and meat processing
