Description |
Treatment of acid mine drainage is carried out by physical, chemical and biological methods. The biological method using sulfate reducing bacteria and
sulfidogenic bioreactor has been proved to be promising in terms of cost effectiveness
and eco-friendly manner of the treatment procedure. After modification of few
characteristics like bioreactor type, reactor flow rate, hydraulic retention time and
efficient immobilizing material for biomass the efficiency of the bioreactor performance
can be enhanced. While the cheap and easily available substrates which can serve as good
nutrients like carbon, nitrogen, phosphorus, they will also increase the rate of sulfate
reduction as well as reactor performance. Several composted and complex organic
substances like sewage sludge, mushroom compost, manure, leaf compost, crab shell
chitin, mussel shell etc. can serve as good and available source of nutrients for sulfate
reducing bacteria. Some of the substrates like sheep manure, crab shell, chitin, mixture of
mushroom compost, cow manure, saw dust, wood chips and cut rice straw have been
reported to remove almost complete sulfate from water in several batch reactor studies.
