| biogeochemistry of the compost bioreactor components of a composite acid mine drainage passive remediation system. | the compost bioreactor ("anaerobic cell") components of three composite passive remediation systems constructed to treat acid mine drainage (amd) at the former wheal jane tin mine, cornwall, uk were studied over a period of 16 months. while there was some amelioration of the preprocessed amd in each of the three compost bioreactors, as evidenced by ph increase and decrease in metal concentrations, only one of the cells showed effective removal of the two dominant heavy metals (iron and zinc) pre ... | 2005 | 15680629 |
| microbiology of a wetland ecosystem constructed to remediate mine drainage from a heavy metal mine. | a pilot passive treatment plant (pptp) was constructed to evaluate the potential of a composite wetland system to remediate acidic, metal-rich water draining the former wheal jane tin, in cornwall, england. the treatment plant consists of three separate and controllable composite systems, each of which comprises a series of aerobic wetlands for iron oxidation and precipitation, a compost bioreactor for removing chalcophilic metals and to generate alkalinity, and rock filter ponds for removing so ... | 2005 | 15680626 |
