Title Activated Sludge for the Treatment of Sulphur-rich Wastewaters Type Journal Article
Year 2002 Publication Miner. Eng. Abbreviated Journal

Abstract The aim of this investigation was to assess the potential of activated sludge for the remediation of sulphur-rich wastewaters. A pilot-scale activated sludge plant was acclimatised to a low load of sulphide and operated as a flow-through unit. Additional sludge samples from different full-scale plants were compared with the acclimatised and unacclimatised sludges using batch absorption tests. The effects of sludge source and acclimatisation on the ability of the sludge to biodegrade high loads of sulphide were evaluated. Acclimatisation to low-sulphide concentrations enabled the sludge to degrade subsequent high loads which were toxic to unacclimatised sludge. Acclimatisation was seen to be an effect of selection pressure on the biomass, suggesting that the treatment capability of activated sludge will develop after acclimation, indicating potential for treatment of acid mine drainage (AMD) by a standard wastewater treatment process. Existing options for biological treatment of AMD are described and the potential of activated sludge treatment for AMD discussed in comparison with existing technologies.

Title Passive mine water treatment as an alternative to active systems Type Journal Article
Year 2002 Publication Grundwasser Abbreviated Journal
Volume (down) 7 Issue 2 Pages 67-77
Keywords Groundwater quality geographical abstracts: physical geography hydrology (71 6 11) water treatment groundwater pollution water quality mine
Abstract For the treatment of contaminated mine waters reliable treatment methods with low investment and operational costs are essential. Therefore, passive treatment systems recently have been installed in Great Britain and in Germany (e.g. anoxic limestone drains, constructed wetlands, reactive barriers, roughing filters) and during the last eight years such systems successfully treated mine waters, using up to 6 ha of space. In some cases with highly contaminated mine water, a combination of active and passive systems should be applied, as in any case the water quality has to reach the limits. Because not all the processes of passive treatment systems are understood in detail, current research projects (e.g. EU-project PIRAMID) were established to clarify open questions.

Title Pitfalls of passive mine water treatment Type Journal Article
Year 2002 Publication Reviews in Environmental Science & Biotechnology Abbreviated Journal
Volume (down) 1 Issue 5 Pages 335-343
Keywords acid mine drainage acidophilic microorganisms heavy metals iron oxidation iron reduction remediation sulfate reduction wetlands Wheal Jane
Abstract Passive (wetland) treatment of waters draining abandoned and derelict mine sites has a number of detrac-tions. Detailed knowledge of many of the fundamental processes that dictate the performance and longevity of constructed systems is currently very limited and therefore more research effort is needed before passive treatment becomes an “off-the-shelf” technology.

Title Mine water tracing Type Journal Article
Year 2002 Publication Geological Society Special Publication Abbreviated Journal
Volume (down) - Issue 198 Pages 47-60
Keywords Groundwater problems and environmental effects Pollution and waste management non radioactive geomechanics abstracts: excavations (77 10 10) geological abstracts: environmental geology (72 14 2) flooding seepage abandoned mine tracer groundwater flow
Abstract This paper describes how tracer tests can be used in flooded underground mines to evaluate the hydrodynamic conditions or reliability of dams. Mine water tracer tests are conducted in order to evaluate the flow paths of seepage water, connections from the surface to the mine, and to support remediation plans for abandoned and flooded underground mines. There are only a few descriptions of successful tracer tests in the literature, and experience with mine water tracing is limited. Potential tracers are restricted due to the complicated chemical composition or low pH mine waters. A new injection and sampling method ('LydiA'-technique) overcomes some of the problems in mine water tracing. A successful tracer test from the Harz Mountains in Germany with Lycopodium clavatum, microspheres and sodium chloride is described, and the results of 29 mine water tracer tests indicate mean flow velocities of between 0.3 and 1.7 m min-1.
