Book excerpt: A critical review is presented on the stabilization/solidification (S/S) of hazardous organic wastes (WASTES). The literature on the S/S of WASTES with cementing agents containing expandable lattice clay binders modified by cation exchange with quaternary ammonium cations (MODIFIED CLAYS) suggests that hazardous organic waste constituents (ORGANICS) may form permanent chemical bonds preventing future releases of ORGANICS into the environment. This conclusion is compared with basic studies on the sorption of ORGANICS from aqueous solutions by soils and MODIFIED CLAYS. This latter literature would suggest that sorption of ORGANICS from aqueous solutions is an equilibrium process wherein the MODIFIED CLAYS buffer the concentration of ORGANICS in the equilibrium aqueous solution rather than a process forming permanent chemical bonds, thereby preventing the movement of ORGANICS into the environment. Often the buffered concentration of ORGANICS in the equilibrium aqueous solution is far in excess of drinking water standards and therefore S/S WASTES are not necessarily environmentally safe. Discussions are presented on difficulties in relating data on the sorption of ORGANICS by MODIFIED CLAYS to conclusions regarding possible retention of ORGANICS against releases to the environment. Overall considerations are then given to the practice of S/S of WASTES at treatment, storage, and disposal (TSD) facilities.

Book Synopsis Critical Review of Cement-Based Stabilisation/Solidification Techniques for the Disposal of Hazardous Wastes by : Alistair Clark
Download or read book Critical Review of Cement-Based Stabilisation/Solidification Techniques for the Disposal of Hazardous Wastes written by Alistair Clark and published by . This book was released on 1986 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The materials used in stabilisation/solidification processes (OPC, PFA and sodium silicate) have been reviewed in terms of their basic composition and chemistry. The addition of inorganic wastes to OPC and PFA has been demonstrated to affect early hydration and has led to the development of the protective coating theory and sorption of heavy metals by PFA as the principal factors involved in stabilization. The aqueous chemistry of OPF, PFA, PFA/OPC and PFA/OPC/SILICATES has also been reviewed and has illustrated the chemical reactions taking place during the first hour of the stabilisation process. Methods to improve the efficiency of the Sealosafe processed have been highlighted particularly with respect to supernatant formation. New developments such as the use of clays have been highlighted.

Download or read book Summary of U.S. EPA Research on Solidified/stabilized Waste Form Long-Term Durability written by DR. Kirk and published by . This book was released on 1996 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Successful performance of solidification and stabilization treatment technologies largely depends on the ability of the treated waste to endure long term exposure to physical and chemical stresses. The available test methods to assess durability of treated wastes rely on results from laboratory tests; these procedures rely on freeze/thaw cycles, elevated temperature, and exposure to various solutions to simulate the stresses exerted on a solidified/ stabilized (S/S) waste form over time. Unfortunately, none of the methods has been verified as replicating field behavior. In addition, the speciation of contaminants is a critical factor in determining long-term immobilization. Research is needed to cover areas which will address the issues associated with long-term performance of S/S waste forms. This paper discusses technical issues associated with long-term behavior of S/S waste forms and U.S. EPA research addressing these issues.
Book Synopsis A SUC Model Study for Solidification/stabilization of Organic Hazardous Wastes with Reactivated Carbon by : Peng Gong
Download or read book A SUC Model Study for Solidification/stabilization of Organic Hazardous Wastes with Reactivated Carbon written by Peng Gong and published by . This book was released on 2001 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cement based stabilization/solidification (S/S) systems have been widely used for immobilization of contaminants in hazardous wastes, particularly for stabilization of wastes that contains heavy metals. However, few have demonstrated that S/S systems can adequately trap and retain organics, since heavy metals in S/S processes are converted into insoluble precipitates, and this does not happen with most organics. Additives that can be used with the inorganic binder to retain organics or render them less hazardous have attracted much interest. Research has found activated carbon to be the best additive for immobilizing organic contaminants. Powdered reactivated carbon was used in this research to retain organics from leaching because it is effective and economically competitive. The cost of reactivated carbon is much less than one-fourth of that for virgin carbon, making its use more attractive to the S/S industry. A difficulty with evaluating S/S systems for immobilization of organics is the lack of a suitable leaching test procedure. The objective of this research was to evaluate the use of leaching tests defined for measurement of inorganic leaching for measurement of organic leaching. The Shrinking Unreacted Core (SUC) leach test method, which was developed by Dr. Paul L. Bishop's research group at the University of Cincinnati, was employed in this study. S/S waste forms were prepared and five organics l phenol, 2-chlorophenol, chlorobenzene, aniline and Methyl Ethyl Ketone (MEK) l were spiked into the waste forms at two concentration levels each. 0% (as control), 1% and 2% reactivated carbon (w/w) were added into each batch of waste forms to determine how effectively the reactivated carbon can immobilize those organics and the optimum dose of reactivated carbon addition. Leachate samples were analyzed using Gas Chromatography. Results show that 1% reactivated carbon addition is enough to reduce leaching of most of the organic contaminants by more than 70%. The leaching behaviors fit the SUC model.
