Efficient dissolved air flotation machine

Main purpose

Effectively removing light and non precipitating flocs from wastewater, such as papermaking wastewater treatment and fiber recovery; Printing and dyeing wastewater treatment; Treatment of wastewater containing various heavy metal ions such as electroplating; Oil containing wastewater treatment; Leather wastewater treatment; Chemical wastewater treatment; Paint wastewater treatment; Food wastewater treatment: acid pickling and phosphating wastewater treatment: separation of sludge and water from biological treatment; Low temperature and low turbidity surface water treatment: municipal wastewater, chemical industry, beverage industry, oil refining industry, food industry, textile industry, slaughter industry, dairy industry, etc. Involving suspended solids separation, oil-water separation and purification, coagulation reaction floc separation, activated sludge separation, etc.

Working principle and characteristics

Dissolved air flotation machine utilizes partially treated reflux water. Through the air floating circulation working pump, it is pressurized and mixed with compressed air in the dissolved air tank. When the air dissolves into water, the dissolved air efficiency reaches over 80%; Decompression release in the air flotation tank. The air dissolved in the water forms 20-30 μ m bubbles and has a high surface area adsorption capacity. Microbubbles combine with suspended solids in wastewater, reducing their specific gravity until they float to the surface of the water; Form a large amount of floating debris. Then, the chain scraper installed on the air flotation tank is used to remove the floating slag and achieve the desired treatment effect.
