Abstract |
Aktuelle Entwicklungen auf dem Gebiet der aktiven Wasserbehandlung im Bergbau in den spezifischen Anwendungsgebieten • Behandlung von sauren Bergbauwässern (AMD – acidic mine drainage) mit Schwerpunkt HDS-Technologie (HDS – high-density sludge) • In-situ-Behandlung bergbaubeeinflusster Grundwasserkörper, insbesondere nach Anwendung der In-situ-Laugung (ISL) • In-situ-Behandlung von Tagebaurestseen mit Schwerpunkt In-lake-Verfahren werden hinsichtlich Machbarkeit, technologischer Kenngrößen und Effizienz bewertet und kommen-tiert. Recent developments in the field of active water treatment technologies in the mining sector are re-viewed. Application areas of interest include • Treatment of acidic mine drainage (AMD) emphasizing HDS technology (HDS – high-density sludge) • In-situ treatment of groundwater affected by mining, in particular after the application of in-situ leaching (ISL) • In-situ treatment of lakes arising in former open-pit lignite mines, in particular the application of in-lake methods The various applications are evaluated with regard to feasibility, technical characteristics and treat-ment efficiency. |

Abstract |
ERWAT's Ancor Wastewater Treatment Works on the Far East Rand commissioned a 10 Ml/day full-scale plant to treat toxic mine-water from the Grootvlei gold mine using primary sewage sludge. The R15-million plant is treating sulphate rich acid mine drainage using the Rhodes BioSURE Process. First, the pumped mine-water is treated at a high-density separation (HDS) plant to remove iron and condition pH levels. Then it is pumped two km via a newly-constructed 10 Ml capacity pipeline to the Ancor works. This mine-water is then mixed together with primary sewage sludge in a mixing tank from where a splitter box directs the material to eight biological sulphate reducing reactors or bioreactors. The overflow water which is rich in sulphide is pumped through the main pump station to another mixing box. Here, iron slurry is mixed with the material before it is again divided between four reactor clarifiers for sulphide removal. The overflow water, now containing reduced sulphate levels and virtually no sulphide is pumped to Ancor's biofilters for removal of remaining Chemical Oxygen Demand (COD) and ammonia following the conventional sewage treatment process for eventual release into the Blesbokspruit. |
