ABSTRACT:
An ACM removal assembly is disclosed, including: a nozzle for directing a pressurized fluid against ACM for dislodging the ACM; a fluid supply reservoir connected to the nozzle; a housing which supports the nozzle and capturingly receives spent fluid and dislodged ACM; and a material handing and separating system which includes coarse separating apparatus for coarsely separating the spent fluid from the dislodged ACM and fluid return conduit for returning coarsely separated fluid to the fluid supply reservoir. Also disclosed is a method for removing ACM from a building structure, including: sealingly circumscribing a small-area building region having exposed ACM with an ACM containment apparatus; removing ACM from the circumscribed building region with a fluid spray blast; combiningly capturing dislodged ACM and spent fluid from the spray blast in the containment apparatus; coarsely separating a portion of the ACM from the combined ACM and spent fluid; and reusing the coarsely separated fluid to remove ACM from the building.
