Abstract

Physical sepn. methods for environmentally harmful material, e.g. waste, contaminated soil or sludges, which contains oil, grease or similar tacky contaminant fractions as well as solid particles, which can be recovered or disposed of after sepn., are claimed. Material is intensively mixed in treatment region to remove surfaces of particles by scrubbing or wear and flow of fluid (pref. air) is simultaneously passed through region to remove oil, grease, etc.. Solid contaminants obtd. by scrubbing particles and decontaminated particulate material are removed separately.
