Technology
1,AIR DISSOLVED SYSTEM:Unique technologyy----- High frequency common railinjection,Powerful centrifugal force from high-speed rotation; micron airintegrated injection system, the ratio of dissolved air to water wasclose to the maximum value of Henry's law in 3 seconds (27%),provide a platform for large scale micro bubbles, the dynamicfactors are greatly reduced.
2,MICRO BUBBLEMANUFACTURING SYSTEM:Special structure for fast phase separation in microsecond, The 2 phases of watermolecules and air molecules in the dissolved gas water are separated from each other indifferent directions in less than 1 microseconds, form a uniform 3-7 m charge bubbleInstantaneously, Under the condition of the same volume of dissolved air, the bubbledensity is geometrically fission, Contact area expansion of micro bubble flotation,improve the surface tension of water molecules by integrated charged bubbles,accelerate the bubble floating rate, adsorption of colored groups and some hydrophiliccolloid. The dissolved air volume is a fixed value, the service area of the micro bubble isinversely proportional to the square of the diameter, the service area of the microbubble can be expanded to hundreds of times, and the density of the micro bubble isincreased to several thousand times, Theoretical research and experimental resultsshow that the smaller the diameter of the micro bubble, the stronger the adsorption ofsuspended matter.
