Advection precipitation flotation machine Overview: advection precipitation flotation machine is the introduction of foreign advanced technology to develop and produce a series of flotation water treatment equipment, mainly used for paper, chemicals, printing and dyeing, oil refining, and other industrial wastewater and urban sewage purification. The device power consumption is only 1/10 of conventional flotation, no mechanical scraper devices, each storage bucket of mud mud tubes set up a separate, independent mud, without disturbing each other, to ensure that the concentration of precipitation. Aerator bubble size can be adjusted in order to ensure the most efficient flocculation, sedimentation flocculation flotation in one set, greatly reducing equipment capital investment. Removal is done by skimming scum and screw conveyor, COD removal efficiency 30% -50%, SS removal rate of 90%.
