Air flotation equipment - cntianlang

Name: Flat flow dissolved air flotation machine. Details The traditional function of the air flotation device is to remove the oil in the emulsified state of the sewage or the fine suspended particulate impurities with a density close to that of water, to promote the adhesion of the bubbles and the particulate impurities and to form the particles with appropriate size.
