What are the components and functions of dissolved air flotation equipment?

1. Pressure dissolved air system:
Pressure pump: used to increase the pressure of the water to be dissolved.
Dissolved air tank: Water is fully in contact with air under high pressure, so that the air is dissolved in the water to form dissolved air water.
2. Dissolved air release system:
Dissolved air releaser: The air in the dissolved air water is released evenly and quickly in the form of tiny bubbles to increase the contact and adhesion opportunities between the bubbles and impurities in the water.
3. Flotation tank:
Contact area: Microbubbles and suspended matter in the water fully contact and collide in this area to form a gas-solid combination.
Separation area: The gas-solid combination floats to the water surface to form scum, realizing solid-liquid separation.
4. Scum scraping system:
Scum scraper: Scrape the scum floating on the water surface to the scum collecting tank for subsequent treatment.
5. Mud discharge system:
Scum discharge pipe and valve: used to discharge the sludge settled at the bottom of the flotation tank.
6. Water collection system:
Water collection tank: Collect the treated clean water and discharge it from the flotation equipment.
