متن کاملEx-situ Treatment of Contaminated Soil – the Dutch Experience
This paper reviews the development of ex-situ soil treatment technologies over the last 20 years, against the background of developing legislation and market forces. Legislation along the lines of site remediation, soil treatment, landfilling and reuse was developed and improved in the eighties and nineties. In addition, substantial budgets were made available by the national government to tack...
متن کاملCoupled Electrokinetics-Adsorption Technique for Simultaneous Removal of Heavy Metals and Organics from Saline-Sodic Soil
In situ remediation technologies for contaminated soils are faced with significant technical challenges when the contaminated soil has low permeability. Popular traditional technologies are rendered ineffective due to the difficulty encountered in accessing the contaminants as well as when employed in settings where the soil contains mixed contaminants such as petroleum hydrocarbons, heavy meta...

On the basis of key ways of oily waste treatment in Russia which has been described in the article and on the example of oil-contaminated soil (OCS) treatment there can be considered two most widespread technologies: bioremediation and thermal recovery. We developed the process flow sheet of the equipment (UT-2S) for industrial oily wastes treatment on the basis of high temperature air tight de...
متن کاملIn Situ Remediation of Arsenic in Contaminated Soils
Owing to its toxic nature and relative abundance, arsenic is a common contaminant of concern in environmental cleanup. Arsenic is identified as a constituent of concern at 728 National Priorities List (NPL) sites as of fiscal year 1998, and arsenic in soil is specifically identified at 32 percent of these sites (Fiedler, 2001). Exposure to arsenic has been linked to a variety of cancers, cardio...
