“…Various treatment technologies have been studied for perchlorate removal from water. Biological treatment is cost-effective for water contaminated with high perchlorate concentration and poor water quality (high organics and suspended solids) [2,[10][11][12]. However, biological processes can be costly for the treatment of large-volume perchlorate-containing waters having low perchlorate concentration because a highly reducing environment is needed to reduce perchlorate.…”

“…This system was operated in a semi-passive mode to provide mixing of cosubstrate with groundwater while minimizing typical O&M issues associated with continuously active pumping approaches. Similar ER designs were shown to be highly effective for in situ treatment of perchlorate at Indian Head Division, Naval Surface Warfare Center (IHDIV NSWC) in Maryland (Hatzinger et al, 2006); at the Longhorn Army Ammunition Plant (LHAAP) in Karnack, TX (Krug and Cox, 2009); and at the former Whittaker-Bermite Site in Santa Clarita, CA (Hatzinger and Lippincott, 2009). To our knowledge, this project represents the first application of a semi-passive ER approach for nitramine and nitroaromatic explosives.…”

“…Among the perchlorate-based salts, ammonium perchlorate is the main source of contamination (Greene and Pitre, 1999). Ammonium perchlorate is used as an additive (oxidizer) in solid rocket propellant (Atikovic et al, 2008;Hatzinger et al, 2006;Logan, 2001), therefore the contamination of water sources near the military sites is available (Aziz and Hatzinger, 2002). Perchlorate anion is suspected to cause the disruption of iodide uptake by the thyroid.…”

The compounds that mainly interfere with perchlorate reduction in contaminated tap water, nitrate and dissolved oxygen (DO), were reduced using a fluidized bed bioreactor. Nitrate was reduced to below the maximum level of contamination adopted by the United States Environmental Protection Agency (EPA), 10 ppm, and the percentages of nitrate were 90, 84 and 80% for concentrations (conc.) of 25, 50 and 100 ppm perchlorate, respectively, after a 6 h hydraulic retention time (HRT). The DO concentration was reduced to less than 1 mg/L, which is considered to be appropriate for the maximum rates of perchlorate anion reduction, and the percentages of DO removed were 80, 83, and 88% for 25, 50, and 100 ppm perchlorate, respectively, after a 6 h HRT. The maximum reduction for perchlorate was obtained with an HRT of 6 h for the different concentrations of perchlorate anion contamination. This result was confirmed by increase in the concentration of free chloride and decrease in the pH values for UP water. The free chloride concentrations increased to 36, 47 and 58 ppm for the 25, 50 and 100 ppm perchlorate concentration, respectively, after the 6 h HRT. The pH values decreased to 6.01, 5.8 and 6.2 for the 25, 50 and 100 ppm perchlorate concentration, respectively, after the 6 h HRT.
