201999In continuousflow column experiments containing SRBmine waste materials effluent pHs above pH 7 and metal removal efficiencies of greater than 99 for Cd Cu and Zn and 87 for Ni were attained due to the activity of SRB in mine waste columns. Key words Acid mine drainage sulfate reducing bacteria mine waste piles

20202292 Fe2 and Mn2 in acid mine drainage AMD and low pH value based on adsorption and biological methods coal gangue was combined with sulfatereducing bacteria SRB. On this basis four dynamic columns including Column 1 SRB combined with spontaneous combustion gangue from the Gaode coal mine Column 2

Sulfatereducing bacteriaSRB was isolated from the loess polluted by acid mine drainageAMD from coal wastes.The aim of this test is to study the possibility of using SRB for remediating sulfuric pollution from coal wasteswhich is considered to be the major

Acidic mine drainage AMD is regarded as a pollutant and considered as potential source of valuable metals. With diminishing metal resources and everincreasing demand on industry recovering AMD metals is a sustainable initiative despite facing major challenges. AMD refers to effluents draining from abandoned mines and mine wastes usually highly acidic that contain a variety of dissolved

Study on Treatment of Acid Mine Wastewater by SulfateReducing Bacteria Effect of CODSO42 Ratio on Sulfate Removal Rate in Acidogenic Sulfatereducing

Sulfatereducing bacteria SRB are bacteria that can obtain energy by oxidiing organic compounds or molecular hydrogen while reducing sulfate to hydrogen sulfide. Most sulfatereducing bacteria can also reduce other oxidied inorganic sulfur compounds such as sulfite thiosulfateelemental sulfur.

Sulfatereducing bacteria SRB are bacteria that can obtain energy by oxidiing organic compounds or molecular hydrogen while reducing sulfate to hydrogen sulfide. Most sulfatereducing bacteria can also reduce other oxidied inorganic sulfur compounds such as sulfite thiosulfateelemental sulfur.

The environment needed for efficient sulfatereducing bacteria growth decreases acid production by reducing the dissolved oxygen in water and increasing pH. A detailed technical description of the sulfatereducing bacteria technology based on an extensive review of the technical literature is presented.

To investigate the effects of longterm acid mine drainage AMD irrigation on the change in bacterial community and sulphatereducing bacteria SRB in a paddy soil. Methods and Results. The bacterial community structures were investigated using 454 pyrosequencing and 98 931 effective sequences were selected for the bacterial diversity

20081029The treatment of acid mine drainage with sulphatereducing bacteria using a twostage bioremediation process showed great capacity to remove high concentrations of sulphate iron copper and inc. An increase of the pH values in the treated AMD was also observed due to the neutraliation and increase in buffer capacity in the calcite tailing

2018630Acid mine drainage AMD occurs when metal sulfides most commonly pyrite are exposed to and react with air and water. When water flows over or through sulfurbearing mine tailings a chemical reaction occurs between the water and rocks resulting in metalrich water.

Industrial activities and the natural oxidation of metallic sulfideores produce sulfaterich waters with low pH and high heavy metals content generally termed acid mine drainage AMD. This is of great environmental concern as some heavy metals are highly toxic. Within a number of possibilities biological treatment applying sulfatereducing bacteria SRB is an attractive option to treat

2020129For sulfate reduction to be successful in treating acid mine drainage the rate of sulfate reduction must be equal to or greater than the rate of acidity input metals acid. If the rate of sulfate reduction exceeds the rate of acidity input excess alkalinity is generated and the

20061115Sulfatereducing bioreactors use special forms of bacteria to remove metals of AMD and add alkalinity. These bacteria convert sulfate an ion present in AMD into both sulfide and bicarbonate. The sulfide then combines with dissolved metals to create an insoluble compound that drops out of
