Interfacial interaction between the bubbles and particles in the flotation process
气浮过程中的界面相互作用

The basic properties of the suspended particles in water body and the bubble nucleation process was presented, then the adsorption of the particles on the stagnant gas/liquid interface was analyzed, the interaction between the suspended particles and bubbles during flotation process was discussed, and the collision models were compared. On the basis of turbulent flotation, a new kind of dissolved air flotation method name counter current co-flocculation flotation (CCC-FF) was put forward. The interfacial interactions in the CCC-FF reactor and their influence on the turbidity removal were analyzed, and the operational parameters of the reactor were optimized. Furthermore, the comparison between the conventional and CCC-FF water purification method was carried out.
