Abstract |
Today's demands for improved water quality in receiving waters are widespread and require the implementation of systems that are natural, low-cost and minimal-maintenance that could effectively treat polluted discharges. Wetlands are such systems and are recently receiving a lot of attention from scientists, ecologists and engineers, as they are deemed appropriate for reducing the impact of effluent and run-off on receiving waters. Since a large part of natural wetlands have been lost-about 53% of them in the United States from the 1780s to the 1980s-management options for improving receiving water quality, water reclamation and reuse involve the application of constructed wetlands technology. |

Abstract |
Applied Biosciences has developed a biological technology for removal of arsenic, nitrate, selenium, and other metals from mining and industrial waste waters. The ABMet((R)) technology was implemented at a closed gold mine site in Canada for removing arsenic from tailings pond water. The system included six bioreactors that began treating water in the spring of 2004. Design criteria incorporated a maximum flow of 567 L/min (150 gallons per minute) and water temperatures ranging from 10 degrees C to 15 degrees C. Influent arsenic concentrations range from 0.5 mg/L to 1.5 mg/L. The ABMet((R)) technology consistently removes arsenic to below detection limits (0.02 mg/L). Data from the full scale system will be presented, as well as regulatory requirements and site specific challenges. |

Abstract |
The first large-scale (1,200 gpm capacity), sulfate-reducing; bioreactor (SRBR) was constructed in 1996 to treat water from an underground lead mine in Missouri. Other large-scale SRBR systems have been built elsewhere since then. This technology holds much promise for economically treating heavy metals and has progressed steadily from the laboratory to industrial applications. Scale-up challenges include: designing for seasonal temperature variations, minimizing short circuits, changes in metal loading rate s, storm water impacts, and resistance to vandalism. However, the biggest challenge may be designing for the progressive biological degradation of the organic substrate and its effects on the hydraulics of the SRBR cells. |

Abstract |
A Mn-oxidizing fungus was isolated from a constructed wetland of Hokkaido (Japan), which is receiving the Mn-impacted drainage, and genetically and morphologically identified as Paraconiothyrium sp.-like strain. The optimum pHs were 6.45-6.64, where is more acidic than those of previously reported Mn-oxidizing fungi. Too much nutrient inhibited fungal Mn-oxidation, and too little nutrient also delayed Mn oxidation even at optimum pH. In order to achieve the oxidation of high concentrations of Mn like mine drainage containing several hundreds g-m(-3) of Mn, it is important to find the best mix ratio among the initial Mn concentrations, inocolumn size and nutrient concentration. The strain has still Mn-tolerance with more than 380 g-m(-3) of Mn, but high Mn(II) oxidation was limited by pH control and supplied nutrient amounts. The biogenic Mn deposit was poorly crystallized birnessite. The strain is an unique Mn-oxidizing fungus having a high Mn tolerance and weakly acidic tolerance, since there has been no record about the property of the strain. There is a potentiality to apply the strain to the environmental bioremediation. |
