Abstract: A system and method for removing asbestos and other hazardous solids from a slurry collected during removal of insulation from pipelines, equipment and other structures. The slurry is collected in a collection pan that is attached to a shroud of a hydrocleaning machine. Solid particles are separated from the slurry by passing the slurry through various stages of filters. Pumps are used to transfer the slurry from the collection pan through the filter stages. A first flocculent is injected into the slurry to coagulate the solid particles into individual masses. A second flocculent is injected into the slurry, downstream from the injection point of the first flocculent, in order to coagulate a majority of the remaining solid particles. The coagulated masses of solid particles are removed by passing the slurry through a screen shaker. The slurry discharged from the screen shaker is then passed through further filters.
