Product Details
Construction and working process
The HFGF type combined air flotation equipment consists of components such as an air flotation tank body, a dissolved air system, a dissolved air return pipeline, a dissolved air water release device, a slag scraping device (which can be used in combination, crane type, or chain plate type according to user needs), and an electric control cabinet.
Air flotation separation technology refers to the process of allowing air and water to dissolve into water to a greater extent under a certain working pressure, striving to be in a saturated state, and then releasing the pressure dissolved gas and water through reduced pressure, generating a large amount of micro
Fine bubbles come into full contact with the suspended flocs in water, causing them to adhere to the micro bubbles and float to the water surface together with the bubbles, forming scum and scraping off the scum, thus purifying the water quality. Air flotation mainly plays a role in solid-liquid separation (while reducing COD, BOD, chromaticity, etc.). After adding flocculants PAC or PAM to the raw water and undergoing effective flocculation reactions (time, dosage, and flocculation effect must be determined by experiments), the raw water enters the combined air flotation contact zone. In the contact zone, micro bubbles in the dissolved air water adhere to the flocs in the raw water and enter the separation zone together. Under the action of bubble buoyancy, the flocs and bubbles rise together to the liquid surface, 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. 

Application scope
Air flotation, as a process in water treatment, is widely used in sewage treatment and water purification engineering. This device is suitable for:
1,Paper white water pulp recycling and water reuse.
2,Removal of various heavy metal ions.
3, Separation of refinery wastewater and oil pollution.
4,Removal of impurities from tannery wastewater
5, Removal of chromaticity and impurities in printing and dyeing wastewater.
6,Various biological treatments and solid-liquid separation using biological sludge membranes.
7, Sludge concentration (with a processing capacity of 30% -50% of the equipment's capacity). 8, Wastewater standardization, purification, and phosphorus removal.
