Combined Remedies Treat Large Industrial Site - Case Study
ABSTRACT BOS 100 was successfully implemented as part of a combined remedies strategy to treat elevated levels of Trichloroethylene in a shallow fine grained aquifer at a former large industrial facility. CHALLENGES A large industrial facility used vapor degreasing in the 1970s and 1980s that resulted in chlorinated volatile organic compound (CVOC) contamination of soil and groundwater. ...

The chemical aspect of NOx scrubbing, pollution engineering
With the passage of the 1990 Clean Air Act Amendments, many chemical and metal industries and utility producers will now be required to further limit the amount of NOx (Nitrogen Oxides) produced. NOx is a precursor to ozone in the atmosphere, and is believed to be a major contributor to acidic deposition (acid rain). Formation of ozone: NOx is produced in a variety of different processes, ...

Dehalogenation
Introduction: Contaminated soil is screened, processed with a crusher and pug mill, and mixed with reagents. The mixture is heated in a reactor. The dehalogenation process is achieved by either the replacement of the halogen molecules or the decomposition and partial volatilization of the contaminants. Base-catalyzed Decomposition (BCD) Base-catalyzed decomposition (BCD) process was developed ...

DOD evaluates bioaugmentation for remediating low-pH aquifers
The US Department of Defense (DOD) has completed pilot-scale work on the 'MAG-1' site at Fort Dix, NJ, to test suitability of anaerobic bioremediation for an aquifer with low pH. Project results will be used to design full-scale ground-water treatment at MAG-1. In addition, technical criteria gained from the demonstration will be integrated into DOD’s remediation strategy for its many facilities ...

A Citizen`s Guide to Chemical Dehalogenation
What is chemical dehalogenation? Chemical dehalogenation is a chemical process to remove halogens (usually chlorine) from a chemical contaminant, rendering it less hazardous. Halogens are a class of chemical elements that include chlorine, bromine, iodine, and fluorine. Polychlorinated biphenyls are halogenated compounds that once were used in high voltage electrical transformers because they ...
