The present invention relates to the field of defoaming equipment, and more particularly, to removing, defoaming, and storing large amounts of foam after a Blast Mitigation or Decontamination Foam has been used in either an open area or in an contained area. The invention provides an apparatus for defoaming, comprising: a vacuum system for collecting foam, the vacuum system including a vacuum head for drawing the foam through a suction hose terminating in a nozzle, the vacuum system feeding the foam into a holding tank; the holding tank initially storing a quantity of defoaming agent; and a pump for drawing the defoaming agent from the holding tank and feeding the defoaming agent to at least one injector, the at least one injector being fitted on the vacuum-side of the vacuum system, whereby the defoaming agent is actively mixed with the collected foam, reducing the collected foam, and the reduced foam and defoaming agent are recirculated through the pump; the nozzle, the suction hose, the vacuum system, the at least one injector and the holding tank being of chemical-resistant construction.
