Defoaming: Antifoams and mechanical methods

Recent progress in both the mode of action of antifoams and mechanical defoaming is reviewed. New insights concern the simulation of the orientation of particles in interfaces and films, the role of dynamic surface effects in antifoam action, antifoam action under micro-gravity, deactivation of oil/particle antifoams and antifoam action in hydrocarbon media. Progress in mechanical defoaming is mainly confined to new insights concerning the use of ultrasound.
