  • Patent number: 4650590
    Abstract: A method is provided for treating polar or aqueous fluid compositions containing an amount of an organic contaminant to immobilize the contaminant by forming a nonflowable matrix containing 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.

  • Patent number: 4549966
    Abstract: A method is provided of removing organic contaminants from an aqueous composition contaminated therewith. The method comprises contacting the aqueous composition with a sufficient amount of organoclay for a sufficient amount of time to absorb a substantial portion of the contaminant, and to form an aqueous organoclay admixture. The organoclay and aqueous composition are then separated from each other. The method is particularly useful for separating oily contaminants from water toxic substance precursors, e.g. humic acid and toxic organics (e.g. PCB) from water.

  • Patent number: 4517094
    Abstract: A method is provided for removing organic contaminants from an aqueous composition contaminated therewith. The method comprises passing the composition through a first column packed with an organoclay, to adsorb substantial quantities of high molecular weight and/or emulsified components of said organic contaminants, and passing the effluent from said first column through further separating means for separating substantial quantities of the low molecular components of said organic contaminants which remain in the effluent from said first column, and recovering the effluent from said separate means as product.

  • Patent number: 4473477
    Abstract: A method for controlling and containing organic material by sorbing it into an organoclay. Solid or liquid waste material or waste material in aqueous solution containing organic material are combined with a sufficient amount of organoclay to sorb and contain the organic material in the organoclay.

  • Patent number: 4470912
    Abstract: A method is provided for treating polar or aqueous fluid emulsions of an organic composition. The method comprises contacting the emulsion with an emulsion-breaking amount of an organoclay to adsorb a major portion of the organic composition. Preferably, a portion of the water or polar fluid is then removed.
