  2. 1. Environmental impact of peat mining : Development of storm water treatment methods

    Author : Bjørn Kløve; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographical and geological engineering; Hydrogeology; drainage artificial floodplaines; phosphorus; suspended solids; nitrogen; erosion; peat mining; peak runoff controll; sedimentation; water treatment; water resources; hydrology; hydraulics; Hydrogeologi; teknisk geologi; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Abstract : Drainage of peatlands increases the transport of suspended solids (SS) and the leaching of nutrients to downstream receiving waters. Increased settling of peat and eutrophication of lakes has been noted in many studies downstream from peat mines. READ MORE

  4. 2. Biogeochemical Processes in Denitrifying Woodchip Bioreactors and their Application in the Mining Industry

    Author : Albin Nordström; Roger Herbert; Fritjof Fagerlund; Gunno Renman; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; water treatment; mine drainage; nitrate; nitrous oxide; DNRA; fermentation; syntrophy; temperature; kväverening; gruvvatten; nitrat; lustgas; DNRA; fermentation; syntrofi; temperatur; Hydrology; Hydrologi;

    Abstract : This thesis evaluates passive denitrifying woodchip bioreactors (DWBs) for the removal of nitrate (NO3-) in neutral pH mine drainage, where water is passed through a carbon-rich porous matrix (e.g. woodchips) for the reduction of NO3- to nitrogen gas. READ MORE

  5. 3. Water powered percussive rock drilling : process analysis, modelling and numerical simulation

    Author : Göran Tuomas; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Abstract : This thesis is devoted to problems, processes and systems related to the recently developed water powered percussive rock drilling method. The technology, which uses ordinary water to drive down-the-hole hammers, has been used to produce more than 6 million meters of blast holes within the mining industry. READ MORE

  6. 4. Sustainable Water Quality Monitoring for Developing Countries in the Context of Mining : Monitoring systems and modelling

    Author : Clemencio Nhantumbo; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Water Quality; Monitoring systems; Modelling; pH and alkalinity;

    Abstract : Mining, seen as a source of revenue in most developing countries, threatens seriously the environment. Mining impacts the water quality and one of the main problems of mining is acid mine drainage. Low pH and high concentration of heavy metals characterize acid mine drainage. READ MORE

  7. 5. Radon in Groundwater- Influencing Factors and Prediction Methodology for a Swedish Environment

    Author : Kirlna Skeppström; Bo Olofsson; Per Erik Jansson; Jon Petter Gustafsson; Gerhard Barmen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Radon; Grondwater; GIS; RV method; Multivariate statistics; Water engineering; Vattenteknik;

    Abstract : This thesis presents a method for predicting radon (222Rn) levels in groundwater on a general scale, within an area of approximately 185 x 145 km2. The method applies to Swedish conditions, where 222Rn is the main contributor to natural radioactivity. READ MORE
