Bacteria's sweet tooth destroys groundwater contaminants
Article Abstract:
Arcadis, Geraghty and Miller of Richmond, CA, has received a patent for its IRZ tecnology, a direct-injection process for treatment of such groundwater pollutants as hexavalent chromium, trichloroethylene and perchloroethylene. The novel technology makes use of the affinity of naturally occuring bacteria for a mollasses-based mixture with special nutrients. The company claims that in one applcation its IRZ technology was able to reduce hexavalent chromium and TCE concentrations by 99.9% at a fraction of the cost of conventional methods.

A new way to lower cost
Article Abstract:
BetzDearborn of Trevose, PA, has developed a new chemical treatment method, specifically designed for benzene removal in desalter effluent brine, commonly found in refineries. The program combines three of the company's EMBREAK chemical components and employs proprietary application technologies to minimize the amount of benzene that remains in the water during the desalting process.
