<p>A method for treating polar or aqueous fluid compositions containing an amount of an organic contaminant to immobilize the contaminant by forming a non-flowable matrix containng the contaminant. The non-flowable matrix can be easily disposed of. The method comprises adding a sufficient amount of organoclay to the fluid composition to absorb substantially all of the organic contaminant. A sufficient amount of solid adsorbent is added to the composition to absorb or react with substantially all of the polar fluid or water to form a substantially non-flowable matrix. Typically, such polar fluids or aqueous compositions are in emulsion form with the organic contaminant, and the addition of the organoclay breaks the emulsion, permitting removal of a portion of the water or polar fluid from the composition to thereby reduce the volume to be disposed of. The method of this invention immobilizes the organic contaminant, in such a manner that it is non-leachable from the matrix.</p> |
