- W2102401881 abstract "Recent laboratory and field studies have shown that injection of Edible Oil Substrate (EOS ® ) into the subsurface can provide an effective, low-cost alternative for the enhanced anaerobic bioremediation of a variety of pollutants including acid mine drainage (AMD). EOS ® is prepared from a mixture of slowly biodegradable emulsified oil (e.g. soybean oil) and easily biodegradable substrates. As AMD impacted water flows thought the treated zone, EOS ® stimulates growth of iron and sulfate reducing bacteria, increasing the pH, reducing sulfate, and immobilizing iron, copper, nickel, zinc and related toxic metals. All materials used in the process are Generally Recognized As Safe (GRAS), food-grade materials (21 CFR 184.1400) for in situ application. The impact of EOS ® treatment on AMD was evaluated in both batch and flow-through column experiments. Batch microcosms were constructed with AMD generating spoils from a former coal mine in Sequatchie Valley, TN, simulated acid mine drainage, and a small liquid inoculum from an anaerobic treatment wetland. Sulfate declined from 1,800 mg/L to 10 mg/L, pH increased from 2.6 to 6.4 and iron was precipitated in a 2:1 molar ratio with sulfate removal. These results demonstrate that EOS ® addition can be very effective in treating AMD and the initial pH does not significantly inhibit microbial growth. Laboratory columns were also packed with mine spoils and received a one time treatment of EOS ® with a microbial inoculum. Simulated AMD was then pumped through the columns with a four-day hydraulic retention time. During passage through the EOS ® treated columns, pH increased from less than 3 to near 6, SO4 was reduced by 75%, and aluminum, copper and zinc were reduced to below the analytical detection limit. In this system, effluent dissolved iron concentrations appear to be controlled by the amount of dissolved sulfide available for precipitation." @default.
