For the removal of tiny suspension and oil that is close to water, air floating separation technology is the most effective way. Qi Floating method is the dissolved gas water generated by the dissolving gas system. After rapidly reducing pressure, a large amount of fine air bubbles are generated in the water. Several bubbles are attached to the surface of the water (or flocculating sewage) suspension or oil on the surface of the water. The suspension with a density is less than 1, which rises to the water surface through buoyancy to separate the solid fluid (at the same time to reduce the water purification method of BOD, COD, color, etc.).
The FJF series combination of air floating equipment produced by the company is the development and design of gas floating series equipment on the advantages of concentrating various air floating equipment. The whole set of equipment is compact and beautiful. The FJF series combined air floating is widely used in various types of sewage treatment projects due to its small occupation of land, saving power, convenient operation, and good treatment effect. The gas -dissolved gas -dissolving gas in the key parts in the device is high, and the processing effect is stable.
The main design parameters of Qi Floating Methods include asking, flocculation time, surface load rate, reflux ratio, and dissolving gas pressure. The hydraulic time of the air -floating tank is 15-30 minutes; the surface load rate is 3 ~ 10m3/(m2.H). According to the requirements of the treatment effect, it can adjust the dissolved pressure and return ratio, and can effectively reduce operation and maintenance costs. In addition, the qi floating method can solve the problems that cannot be solved in the precipitation method, and due to the short residence time, the infrastructure cost of the gas floating pool is less than the precipitation pool, but it can achieve better treatment results. For the treatment of the above situation, air floating technology is one of the most effective measures for solid fluid separation (including oil and water separation), and it is also one of the key items in separation technology.
