6. Weathering of mining waste rock containing alum shale and limestone
Sammanfattning : Geochemical processes occurring in the waste rock dumps ofan old phosphate mine, located in Maardu, northem Estonia, havebeen studied and modelled. The waste rock contains pyritic,metalliferous and organic-rich shale, as well as limestone.Production of acidity during pyrite oxidation is a potentialmechanism for heavy metal release. LÄS MER
7. Modeling Flow and Solute Transport in Packed Beds : Applications in On-site Wastewater Treatment Systems
Sammanfattning : The use of separate phosphorus (P) filter units containing replaceable filter materials with a high P binding capacity have been suggested as an appropriate passive method to treat the P from pre-treated domestic wastewater in on-site facilities. A large number of materials have been identified and suggested as being potentially suitable for such filters. LÄS MER
