“…But this increase in oxidation associated with the rhizosphere may be due to a combination of plant induced oxygenation and iron bacteria Bhumbia,1988, Brenner et al 1995). In addition to iron oxidizing bacteria, manganese oxidizing bacteria and fungi have been shown to be the primary source of manganese removal from AMD in constructed wetlands (Brenner et al 1995, Robbins et al 1999.…”

Abstract:The efficiency of a scale model vertical flow wetland (VFW) and aerobic wetland system in treating acid mine drainage was monitored over a two year period. The vertical flow system was constructed using a mixture of mushroom compost and limestone and the aerobic wetland was a cattail (Typha latifolia) dominated system constructed with mushroom compost as the planting medium. Water samples were collected weekly and analyzed for pH, acidity, alkalinity, iron, manganese, iron and manganese oxidizing bacteria. There was nearly a three unit increase in pH (3.73-6.65) along with a 83% reduction in acidity from an average of 300 mg/L to 50mg/L (83%) and corresponding net alkaline discharge of between 40-9 mg/l. The average iron concentrations were reduced from 32 to 4 mg/l (88%), but only an average of 2 mg/L (11%) of manganese was removed with all manganese reductions occurring in the aerobic wetland. The efficiency of the system varied seasonally, as well as between years, and the reductions in iron and manganese concentrations were correlated with bacterial activity within the systems. The majority of reduction in acidity in the VFW occurred within the upper 45 cm of the substrate, whereas alkaline addition and metal removal occurred between 45 and 90 cm of substrate depth. The efficiency of the systems decreased in the second year of operation. The efficiency of the scale model was similar to systems currently treating acid mine drainage in northwestern Pennsylvania.

“…Robbins and Ziemkiewicz (1999) observed the presence of 12 different biological mechanisms removing Mn in a passive treatment system at the Shade coal mine which was constructed in the early 1990s (Brant and Ziemkiewicz 1997). At this site, influent Mn concentrations were reported reduced from 12 to 25 mg/L down to less than 2 mg/L.…”

Abstract. The Empire Mine State Historic Park near Grass Valley, California offers the ever-curious public a unique step back in time by preserving the underground mining heritage of the western slope of the Sierra Nevada. Perennial flow of a neutral pH, mining influenced water containing iron, arsenic, manganese, and other trace metals through the Magenta Drain adit is an unfortunate legacy of that heritage. Peak Magenta Drain flows requiring treatment are expected to be 4,740 L/min (1,200 gallons per minute). Several active treatment options were evaluated, including traditional lime dosing and green sand; alternative passive treatment technologies, including biochemical reactors, were also considered. However, bench scale test results suggested that simple settling of suspended iron oxy-hydroxide (with co-precipitated arsenic) and passive aerobic precipitation of manganese oxide could satisfy discharge targets.Land area in the vicinity of the Magenta Drain portal was inadequate to site the passive treatment system in a manner that would allow gravity flow. Land was available, however, near the crest of a nearby ridge. Consequently, the design included an influent pumping system, overland pipelines, settling pond, and two styles of aerobic wetlands. Once the decision to embrace a passive treatment system concept based on life-cycle cost and appropriateness for a public historic park was made, design plans and specifications were developed on a fast-track basis. The paper summarizes the rationale for the selection of passive treatment and provides design details that include trace metal removal in an aerobic environment.

“…is extremely slow. However, the formation of these compounds is facilitated and catalyzed in nature by common microorganisms (Brock et al 1994;Ghiorse 1984;Ghiorse and Ehrlich 1992;Robbins et al 1999;Tebo et al 2005). The bacteria are aerobic heterotrophs that use dissolved oxygen (DO) to oxidize organic matter as a source of energy.…”

acid neutralization and oxidation and precipitation of the resulting metal flocs. Before selecting an appropriate treatment technology, the AMD conditions and chemistry must be characterized. Flow, acidity and alkalinity, metal, and dissolved oxygen concentrations are critical parameters. This paper reviews the current state of passive system technology development, provides results for various system types, and provides guidance for sizing and effective operation.Keywords Anoxic limestone drains · Bioreactors · Limestone leach beds · Low-pH Fe oxidation channels · Open limestone channels · Wetlands Acid Mine DrainageOxidation of pyritic materials during and after mining produces sulfuric acid and metal ions. These products react with host rock and surface and groundwater to create a range of water chemistries from pH 2 to 8 and elevated ion concentrations. Such waters have traditionally been called acid mine drainage (AMD) and alkaline mine drainage. I n this paper, we use AMD when the water is acidic and state clearly in the text when the water being referred to is not acidic. When AMD enters surface water bodies, biotic impairment often occurs through direct toxicity, habitat alteration by metal precipitates, nutrient cycle alterations, or other mechanisms, and the water often becomes unsuitable for domestic, agricultural, and industrial uses. The process of pyrite oxidation and its effects on water resources have been known for centuries (Nordstrom 2011;Seal and Shanks 2008) and AMD is a worldwide concern (Younger and Wolkersdorfer 2004). Damaging effects of AMD have been described by researchers in Asia (David 2003; Wei Abstract When appropriately designed and maintained, passive systems can provide long-term, efficient, and effective treatment for many acid mine drainage (AMD) sources. Passive AMD treatment relies on natural processes to neutralize acidity and to oxidize or reduce and precipitate metal contaminants. Passive treatment is most suitable for small to moderate AMD discharges of appropriate chemistry, but periodic inspection and maintenance plus eventual renovation are generally required. Passive treatment technologies can be separated into biological and geochemical types. Biological passive treatment technologies generally rely on bacterial activity, and may use organic matter to stimulate microbial sulfate reduction and to adsorb contaminants; constructed wetlands, vertical flow wetlands, and bioreactors are all examples. Geochemical systems place alkalinity-generating materials such as limestone in contact with AMD (direct treatment) or with fresh water upgradient of the AMD. Most passive treatment systems employ multiple methods, often in series, to promote 1 3Mine Water Environ (2017) 36:133-153
