چکیده
The development of low-operational-cost and low-operational-complexity active sulphate (SO4) reducing bioremediation for Acid Mine Drainage (AMD) is an ongoing pursuit towards sustainable mining. This study introduces a fixed bed pervious concrete anaerobic bioreactor as second stage AMD remediation process. investigated the pH self-regulation capabilities, SO4 capabilities rate limiting parameters using glucose organic matter source. was pre-treated permeable reactive barrier. A 21-day trial comprised increase in loading while undertaken to identify performance conditions. daily average concentration reduction 55.2% achieved over initial 13 days experiments. found that COD ratio VFA alkalinity below 5:1 0.5:1 respectively were limiting. capable self-regulating within neutral range 6.5 7.5. findings indicate design can reduce operational costs complexity bioremediation.

متن کاملBioremediation for Acid Mine Drainage: Organic
Biological sulfate reduction has been slowly replacing chemical unit processes to treat acid mine drainage (AMD). Bioremediations for AMD treatment are favored due to their low capital and maintenance cost. This paper describes the available AMD treatment, current SRB commercialization such as THIOPAQ® and BioSulphide® technologies, and also the factors and limitations faced. THIOPAQ® and BioSu...
متن کاملAlternative substrates of bacterial sulphate reduction suitable for the biological-chemical treatment of acid mine drainage
The impacts of AMD pollution on biological systems are mostly severe and the problem may persist from many decades to thousands of years. Consequently AMD prior to being released into the environment must be treated to meet government standards for the amount of metal and non-metal ions contained in the water. One of the best available technologies for the removal of metals from AMD is precipit...
