The device includes at least one hydroblasting head fed by a high pressure unit and connected to a vacuum source comprising a low pressure source connected to a cyclone head mounted on a container which collects water containing toxic products and residues of the support. A filtration system having a filtering press is provided. The filtering press is fed with water containing toxic products collected in the container and whose output feeds a buffer tank wherein the water from the filtration comprises particles less than or equal to 5 μm.
