Dairy workshop wastewater treatment dissolved air flotation machine

Dairy workshop wastewater treatment dissolved air flotation machineSuitable for processing water with low turbidity, high chromaticity, high organic content, low oil content, low surface active substance content, or rich algae. Compared to other air flotation methods, it has the advantages of high hydraulic load and compact tank body. However, its complex process, high energy consumption, and loud noise from the air compressor also limit its application.

Dissolved air flotation is mainly used for efficient aeration of air flotation tanks in industrial wastewater treatment processes such as petrochemicals, textiles, food, papermaking, printing and dyeing, brewing, pharmaceuticals, and leather making, as well as urban domestic wastewater treatment processes. According to the actual aeration volume requirements, single or multiple units can be selected, which have the characteristics of large and sufficient aeration volume per unit, no need for air compressor and dissolved gas tank, small and dense bubbles, and low power consumption.

The working principle of air flotation equipment is to form a saturated dissolved gas carrier in a dissolved gas tank with an appropriate amount of air and some reflux water under a certain pressure (0.35~0.45Mpa). After sudden pressure reduction by a release device, a large number of fine bubbles are obtained, which quickly adhere to the flowing particles, emulsified oil, bath and flocs in the water, causing the flocs to have a specific gravity lower than that of water and be forced to suspend on the water surface, thereby achieving solid-liquid separation.

Dairy workshop wastewater treatment dissolved air flotation machineIt can effectively remove suspended solids and organic matter in wastewater, including oils, proteins, pigments, etc., thereby significantly improving the appearance and odor of wastewater and enhancing the treatment efficiency of wastewater.
