Abstract:
An electrostatic waste separation process for abrasive blasting residues containing an abrasive media and a hazardous material such as lead-based paint. A preconditioning stage as well as a postconditioning stage is used in addition to the electrostatic separation step. Preferably the preconditioning stage consists of the following steps: (a) a size classification step; (b) a ferromagnetic separation step; and (c) a gravity separation step. The concentrated hazardous material separated by this process can then be packaged in a container which can be safely transported, stored or disposed of. The nonhazardous blasting media may be recycled and reused or disposed of as a nonhazardous material.
