Description:
This document provides an evaluation of the performance of the Bergmann USA Soil/Sediment Washing System and its applicability for the treatment of soils or sediments contaminated with organic and/or inorganic compounds. oth the technical and economic aspects of the technology were examined. emonstration of the Bergmann USA unit was conducted under the Superfund Innovative Technology Evaluation Program at the U.S. Army Corps of Engineers' Confined Disposal Facility in the Saginaw Bay of Lake Huron. perational data, along with sampling and analysis information, were carefully compiled to establish a data base against which other available data, as well as the vendor's claims for the technology, have been compared and evaluated. onclusions concerning the applications at other sites with different contaminants and soil types were drawn. he following conclusions were derived mainly from the results of the Demonstration Tests and supported by other available data: (1) the process effectively separates the 45-micron particles, the coarse fraction (45-microns), and the humic fraction from the input feed; (2) PCB contamination in the input feed was concentrated and isolated in the output fines and output humic fraction; the larger coarse fraction was greatly reduced in PCB contamination; (3) the distribution of inorganic contaminants in the output streams echoed that of the PCBS; (4) the volume reduction of contaminatedmaterial in the output streams is a cost effective approach to site remediation prior to utilizing more expensive treatment technologies.
