Abstract

A computer based material processing system 10 allows for the processing of contaminated material in a manner which allows the material to be discharged into a sewage facility or placed in a landfill.

Claims

1. A material treatment system comprising:

an input means for receiving a material to be cleaned;

a computer means coupled to said input means, said computer means storing a reported description of a material to be cleaned, means for obtaining a sample of the material to be cleaned, and an analyzer for determining the actual consistency of the waste from the sample, said analyzer communicating with said computer to compare the actual consistency of the material to be cleaned with that reported by the waste description, and update the memory of the waste description should the two differ, means for determining whether the material can be processed by the system based on the actual consistency of the material;

means for selectively heating and cooling the material; and

conveyer means for moving said material outwardly after having been cleaned.

2. A material treatment system as recited in claim 1 wherein said computer and said analyzer are also capable of checking for a pH content, for PCB concentration, checking for the flash point of the material, checking the material for toxic metals, and checking for volatile components, and said computer means being adapted to make said determination of whether processing of the material is allowable based upon these detected parameters, and only allowing processing of the material after this determination is made.

3. A method of treating a material comprising the steps of:

providing a computer;

providing a material to be cleaned to the system, a waste description being associated with the material;

storing that waste description in the computer;

analyzing a sample of the actual material, and comparing the analyzed sample with the description stored in the computer;

updating the computer record if the actual analyzed sample differs from that in the description;

the computer making a determination of whether the particular material can be processed;

heating the material if the computer determines the material can be processed; and

causing a cleaned material to be outputted of the system.

4. A method as recited in claim 3, wherein the computer makes the further steps of:

checking the material for pH content;

checking the material for PCB concentration;

checking the material for its flash point;

checking the material for the presence of toxic metals;

checking the material for the presence of volatile compounds; and

said computer then making said determination of whether processing of the particular material can be made based upon the content of the material; and

processing the material to clean the material only proceeding after the computer has made this initial determination.
