Permeable reactive barrier design
WebSuch information is significant to the optimal design of a permeable reactive barrier, as incomplete dechlorination of a highly chlorinated ethene, for example, could produce an intermediate product, such as VC, which is more hazardous and more persistent than the parent compounds. Even very low concentrations of undesirable by-products in the ... WebUntil now. Permeable Reactive Barrier: Sustainable Groundwater Remediation brings together the information required to plan, design/model, and apply a successful, cost-effective, and sustainable PRB technology. With contributions from pioneers in this area, the book covers state-of-the-art information on PRB technology.

A field-scale application of PRBs in groundwater remediation consisted of a treatment zone formed by excavating an area isolated by sheet piles, refilling the hole with a mixture of granular iron and sand, and removing the sheet pile to leave an in situ, permeable, iron-bearing treatment zone. The contaminants, chlorinated ethylenes (PCE and TCE), were removed, leaving, for the most par… WebIn most U.S. climates, vapor barriers, or -- more accurately -- vapor diffusion retarders (vapor retarders), should be part of a moisture control strategy for a home.
