Abstract

Abstract: In induced gas floatation，the factors that influence oil removal efficiency are oil droplet size，bubble size and the chemical properties of the oil-drop surface. The surfactants,poly-mers and inorganic coagulant can be added to reduce the bubble size and the electric potential of the oil-drop surface，and to increase the oil droplet size，thus improving the oil removal efficiency.

Key words: Oily sewage, Oil water separation, Surfactant, Polymer
