A method and apparatus for cleansing or restoring polluted substances such as soil or sludge has a horizontally mounted main conveyor which moves a polluted substance which is continually dispensed thereon from a main hopper. A pulverizer mounted proximate the main hopper breaks up the polluted substance into relatively small uniform particles before it is dispensed into the auger of moving means. Immediately downstream of the main hopper, in embodiments which require it, is a dry powder hopper for dispensing fly ash, lime, or other absorbent substance, depending on the process being used onto the polluted substance, or after, as it moves from a first to a second location. At the second location the substance is received by an auger apparatus operating in an elongated, angularly disposed, tubular mixing channel. As the contaminated substance and absorbent substance is moved through the auger apparatus, an oxidizing substance is applied thereto which by the nature of the auger is mixed into the absorbent and polluted substance to cause a reaction to take place and form reaction byproducts which are more environmentally acceptable. While this is taking place, a vacuum is simultaneously applied to the chamber to draw off the reaction byproducts and pass them through a cleansing or treating apparatus, preferably consisting of carbon drums, to cleanse and purify the air before it is returned to the atmosphere.
