Product details
Combination air flotation equipment for food processing wastewater treatment
Characteristics
Small footprint, low power consumption, easy operation, and simple management
High gas dissolution efficiency, stable processing effect, and integrated control of machinery, electricity, and instruments
Adopting GFA type gas dissolution system, it has a clever structure and a gas dissolution efficiency of over 95%. It has multiple self-developed technologies and strong anti clogging ability that other gas dissolution devices do not possess.
Adopting a new type of dissolved gas release device, the gas release efficiency is high, and the average particle size of microbubbles is only 15-30 microns.
Adopting a chain plate scraper, it runs smoothly and reliably, with high scraper efficiency.
Construction and working process
Combination air flotation equipment for food processing wastewater treatmentIt consists of components such as air flotation tank body, dissolved air system, dissolved air reflux pipeline, dissolved air water release device, slag scraping device (which can be combined, crane type, or chain plate type according to user needs), and electric control cabinet.
Air flotation separation technology refers to the process where air and water, under a certain working pressure, dissolve gas into water to the maximum extent possible, striving to be in a saturated state. Then, the formed pressure dissolved gas water is released through depressurization, generating a large number of fine bubbles that fully contact the suspended flocs in the water. The suspended flocs in the water adhere to the microbubbles and float to the surface with the bubbles, forming floating debris and scraping it off, thereby purifying water quality.
Air flotation mainly plays a role in solid-liquid separation (while reducing COD, BOD, chromaticity, etc.). Add flocculant PAC or PAM to the raw water, and after effective flocculation reaction (time, dosage, and flocculation effect must be determined experimentally), the raw water enters the combined air flotation contact zone. In the contact zone, microbubbles in the dissolved water and 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 liquid surface, forming floating slag. The floating slag is scraped to the sludge area by the scraping device. The clean water in the lower layer flows automatically to the clean water tank through the collection pipe. Part of the clean water is refluxed for use in the dissolved gas system, while the other part is discharged.
