Abstract
A liquid foam system and process for treating an aqueous medium volume includes foam breaking equipment for treating foam floating on a liquid medium. The foam breaking equipment includes a foam conveyer, a rotatable driven screw for sucking foam present in the foam conveyor and for causing at least a partial defoaming of the foam and for expelling foam out of the foam conveyor, and an exhaust gas tube for removing gas within the foam conveyor released from the foam during defoaming. The foam breaking equipment may be used in conjunction with a first tank having a liquid medium and the process includes conveying foam downwardly into the foam conveyor and at least partially defoaming the conveyed foam.
