Principle and method of water purification characteristics flotation flotation device in the case of high pressure, the amount of gas dissolved in water as the working fluid, when the sudden decompression flotation equipment manufacturing, numerous minute bubbles released after mixing the reaction with water impurities are bonded together flotation device to gravity less than a flotation device sold, while floating on the surface, forming a bubble (gas, water particles) mixture, allowing the separation of contaminants from wastewater, to purify effect Diving dissolved air impeller system This system is similar to the long axis of vertical pumps, motors placed in the upper part of its power through linkage with the lower dissolved air impeller shaft is connected. Diving dissolved air flotation tank in place at the time of the impeller, the motor above the water, submerged in water impeller flotation tank. When the impeller rotates, part of the return water back into the impeller housing. While producing a negative pressure within the housing, the intake air is connected to the atmosphere through the vent tube. Water mixed with return air after the formation of dissolved air impeller pressurized water directly distributed in the flotation pool.
