ABSTRACT:
This invention relates to a method of producing a drum and paddle assembly for the accelerated remediation of a contaminated material. The method comprises providing at least one paddle which is connectable to, and extendable outwardly from the periphery of, an elongate cylindrical drum. The drum has a longitudinal axis and generates an air stream at a velocity sufficient for entraining the contaminated material therein. Also, it is employed for microenfractionating the contaminated material so that the contaminated material is treated with at least one chemical amendment prior to, and/or during, and/or subsequent to, microenfractionating the contaminated material. Each of the paddles comprises a body having a first planar portion having a leading edge and a second planar portion connected at a first angle to the first paddle portion. The second planar portion is oriented so as to generate a first material-entraining air stream when the drum is rotated, and a base portion connected to the body for mounting the paddle onto the drum. At least one the paddle is mounted onto the drum.
