Preface Uranium is a radioactive element and a heavy metal which is naturally occurring in ground and surface water. Although uranium is enriched in granites and gneiss ground water from these host rocks often shows low to intermediate uranium con centrations, while some ground waters from sandstone and carbonate aquifers show elevated uranium concentrations up to several hundred mg/1 without man made impact. On the other side, surface water contains increased anthropogenic uranium concentrations due to the intensive use of phosphate fertilizers and in mining areas due to mining and milling...

This book accompanies you on a journey that starts with the basics of mine water treatment and takes you further through correct sampling for planning to active and passive systems. In the respective chapters you will learn the most important techniques about the parameters to be measured (e.g. on-site parameters, flow rate), which methods are available to actively treat your mine water (e.g. high density sludge method, reverse osmosis, ion exchange) and which ones to perform passive treatment (e.g. constructed wetlands, vertical flow reactor, limestone channel). You will also get an insight...
