Bench scale treatability method for evaluation of soil washing

摘要

A process for determining the suitability of soil washing for various types of soils, sludges and other solids is disclosed. The process may be applied to relatively small soil samples which have been contaminated in order to determine the suitability and economics for treating the tested soil using a full-scale soil washing process. The process involves the steps of identifying the contaminated particle size ranges contained in the soil sample, identifying an effective extractant for removing the contaminant of interest, and identifying an effective leachate treatment approach for the particular soil sample of interest.
