Influencing factors of heavy metal acid wastewater
Acid mine drainage reduces radioactivity in fracking waste
Acid mine drainage reduces radioactivity in fracking waste

Much of the naturally occurring radioactivity in fracking ,wastewater, might be removed by blending it with another ,wastewater, from ,acid mine, drainage, according to a Duke University-led study.

Two litres of activated sludge of municipal ,wastewater, is added to the ,microorganisms,’ growth tank. The media composition for growth of ,microorganisms, contains 4 L distilled water. Furthermore, 8 g phosphate dihydrogen potassium, 8 g ammonium nitrate and 12 g sucrose are dissolved in one litre distilled water and then added to the mixture.

22/1/2014, · The present study aims firstly at determining the microbial diversity of ,mine,-water collected in Emalahleni, South Africa and secondly isolating and characterizing the most dominant bacterial species found in the ,mine, water in terms of its resistance to both V 5+ and Ni 2+ in a modified ,wastewater, liquid media. The results revealed a microbial diversity of 17 orders, 27 families and 33 …

These bacteria are known to catalyze the oxidation of pyrite (Fennessy & Mitsch 1989). How does a wetland remove AMD? Wetlands have several functions that aid in the removal of metals in drainage and ameliorate

This ,acid mine drainage, (AMD) is generated when metal sulfide minerals, mainly pyrite, are oxidized in the presence of water and accelerated by the action of chemolithotrophic bacteria. This generates acidity and mobilizes large concentrations of iron (Fe), and other toxic trace metals and metalloids, depending on the composition of the exposed rock ( Robb, 1994 ; Mason, 2002 ).

When waste streams entered in to water bodies, biodegradation of the organic pollutants initiates. Oxygen is consumed by microorganism for their respiration, metabolic activities and proliferation. This situation drastically reduces the level of free oxygen available in the water.
