Dissolved Air Flotation Machine
Dissolved air flotation is a process that removes fats, oils, and other small suspended solids, reducing COD and BOD. Use bubble flotation. Air is dissolved in water, and the saturated water microbubbles generated by the dissolved air adhere to the solid surface. The low density of light solids compared to water elevates them to the surface and distributes them throughout the entire groove width, ensuring the best image liquid separation effect. The mechanical skimmer is used to remove the scum layer, and the purified wastewater is dis - charged into the next process. The dissolved air flotation machine adopts new and efficient dissolved air equipment - a micro bubble generator, which replaces traditional air entrainment equipment to dissolve air into water. Several inclined tube groups are installed in the air flotation area, including a box body, a scraper, and a spiral discharge machine, to form a complete air flotation water purification device .
The dissolved air flotation machine is composed of components such as the air flotation tank body, dis - solved air system, dissolved air return pipeline, dissolved air water release device, foam scraping device, and electric control cabinet. Air flotation mainly plays a role in solid -- liquid separation. After adding flocculants PAC or PAM to the raw water, the effective flocculation reaction time, dosage, and flocculation effect must be deter - mined experimentally, and the raw water enters the combined air flotation contact zone. In the contact zone, the microbubbles in the dissolved water and the flocs in the raw water adhere to each other and enter the separation zone together. Under the buoyancy of the bubbles, the flocs and bubbles rise together to the page, forming scum. The scum is scraped from the scraping device to the sludge area. The clean water in the lower layer flows automatically to the clean water tank through the water collection pipe. Some of the clean water flows back for use in the dissolved gas system, while the other part is discharged. Returned clean water passes through the jet suction device, and under a certain working pressure, the air is maximally dissolved into the water, becoming dissolved water. The dissolved water is released in the air flotation contact area through rapid pressure reduction by the release device, forming micro bubbles with a diameter of around 30um--50um. This microbubble can bond with the flocs in the raw water .
