Abstract: A method for removing contaminating material from a combination material containing the contaminating material and a reusable material includes placing the combination material in an enclosed perforated container, placing the container in in a tank having a cleaning fluid with microorganisms therein capable of consuming at least a portion of the contaminating material, whereby the microorganisms will cause separation of the contaminating material from the reusable material and the cleaning fluid and will cause the contaminating material to rise to the top surface of the cleaning fluid, skimming off the risen contaminating material from the top surface of the fluid, leaving the container in the fluid until the contaminating material is separated from the reusable material, and removing the container from the tank with only the reusable material left therein, the contaminating material being substantially removed therefrom.

Abstract: The apparatus of the present invention includes a dryer for reusable material which includes a housing having a top, bottom wall, and a side wall that together define a chamber. A flue connects a fan to the chamber. A heating mechanism is positioned adjacent the flue and thereby in communication with the drying chamber. The fan displaces air warmed by the heating mechanism toward an opening in one of the top, bottom wall or side wall and through a removable porous basket for holding remediated material that can be adapted to fit in covering relation over the opening. Thus, the reusable remediated material is quickly dried. This dryer can be used in combination with a washer tank and a quick-dumping removable porous basket adapted to fit into the tank and hold the remediated materials during washing as well as drying.

Abstract: A method for removing a contaminating material from a combination material containing the contaminating material and reusable material includes placing the combination material in a tank having cleaning fluid therein capable of separating the contaminating material from the reusable material, the cleaning fluid containing oxygen consuming microorganisms capable of also consuming at least a portion of the contaminating material; circulating oxygen through the cleaning fluid so as to provide oxygen for consumption by the microorganisms; circulating the cleaning fluid around the combination material within the tank whereby cleaning fluid will cause the contaminating material to separate from the reusable material and will cause at least some of the contaminating material to float on the top surface of the cleaning fluid within the tank; drawing off the contaminating material which is floating on the top surface of the cleaning fluid and removing it from the tank; and recirculating the cleaning fluid through the

Abstract: The apparatus of the present invention includes a tank containing a cleaning fluid having microorganisms therein. The material to be cleaned is placed within the tank and the microorganisms separate the contaminates from the material to be cleaned. The cleaning fluid is recirculated continuously through the cleaning tank and the contaminates are drawn off of the fluid within the container as the contaminates rise to and float upon the top surface of the fluid within the container.
