The product is characterized by a specially designed high-speed rotation of the gas-liquid mixing generator, and specially designed from ejection outlets at an appropriate pressure, while the pressure change in the gas-liquid interface between the high shear and high-frequency extreme conditions generate a lot of water under the micro and nano-level bubbles. The use of highly dispersed nanoscale small bubbles as a carrier adhered to the wastewater waxes, oils, making it larger than the buoyancy of gravity and resistance, so that the wax, oil floating to the surface, to achieve water separation wax or oil-water separation, higher efficiency, effectiveness more thoroughly.
