water pollution biological Sulphate removal technology sulphate acidity metals treatment technique |
| Abstract |
Mining is implicated as a significant contributor to water pollution, the prime reason being, that pyrites oxidize to sulphuric acid when exposed to air and water. Mine effluents, often containing sulphate, acidity and metals, should be treated to render it suitable for re-use in the mining industry, for irrigation of crops or for discharge in water bodies. This study describes the removal of all three mentioned pollutants in mine effluents, from different origins, containing different concentrations of various metals. The objectives were achieved, applying the biological sulphate removal technology, using ethanol as the carbon and energy source. It was shown that diluting the mine effluent with the effluent from the biological treatment, the pH increased due to the alkalinity in the treated water while the metals precipitated with the produced sulphide. When this treatment regime was changed and the mine water was fed undiluted, it was found that the metals stimulated the methanogenic bacteria (MB) as trace elements. This resulted in a high COD utilization of the MB, such that too little COD was available for the SRB. Metal removal in all three studies was observed and in most instances the metals were eliminated to the required disposal concentration. |

mining uranium mining passive treatment Saxony mine water treatment |
| Abstract |
Treatment of radioactively-contaminated and metal-laden mine waters and of seepage fiom tailings ponds and waste rock piles is among the key issues facing WISMUT GmbH in their task to remediate the legacy of uranium mining and processing in the Free States of saxony and rhuringia, Federal Republic of Germany. Generally, contaminant loads of feed waters wn aimnisn over time. At a certain level of costs for the removal of one contaminant unit, continued operation of conventional water treatment plants can hardly be justified any longer. As treatment is still required for water protection, there is an urgent need for-the development and implementation of more cost efficient technologies. WISMUT GmbH and BioPlanta GmbH have studied the suitability of helophye species for contaminant removal from mine waters. In a fust step, original waters were used for an in vitro bioassay. The test results allowed for the determination of the effects of biotic and abiotic factors on helophy'tes'tolerancer ange, growth, and uptake capability of radionuclides and metals. Test series were carried out using Phiagmites australis, Carex disticha, Typha latifolia, and Juncus effusus. Relevant cont-aminant components of the mine waters under investigation included uraniunl iron, arsenic, manganese, nickel, and copper. Investigations led to a number of recommendations conceming plant selection for specific water treatment needs. In a second step, based on these results, a constructed wetland was built in l99g as a pilot plant for the treatment of flood waters liom the pöhla-Tellerhäuser mine and went on-line. Relevant constituents of the neutral flood waters include radium, iron, and arsenic. This wetland specifically uses both physico-chemical and microbiological processes as well as contaminant accumulation by helophytes to achieve the treatment objectives. with the pilot plant in operation for three years now, average removal rates achieved are 95 Yo for kon, 86 yo for arsenic, and 75 % for raäium. WISMUT GmbH intends to put a number of other projects of passive/biological mine water treatment into operation before the end of 2001_ |
