Research on Application of Hydrocyclone Microbubbles Generator in Flotation of Oil-Water Emulsion

Abstract With the improvement of environmental protection requirements, economical and efficient oily wastewater treatment methods have become a research hotspot. At same time, characteristics microbubbles (large specific surface area, high zeta potential, rises slowly) make it very widely used in various fields, including wastewater. There are many to generate microbubbles, each method has its own applicable fields. In order better apply separation emulsified, experiment hydrocyclone produce microbubbles. The ability separate oil-water emulsions verified by combining visual processing with oil content testing. shows that can large number small-sized stable emulsion for more than 30 minutes. addition, float emulsified concentrate on water surface. After be easily separated from oil.
