EPA's Mobile Volume Reduction Unit for Soil Washing

摘要

The paper discusses the design and initial operation of the U.S. Environmental Protection Agency's (EPA) Mobile Volume Reduction Unit (VRU) for soil washing. Soil washing removes contaminants from soils by dissolving or suspending them in the wash solutions (which can be later treated by conventional waste water treatment methods) or by volume reduction through simple particle size separation techniques. Contaminants are primarily concentrated in the fine-grained (
