    Abstract : In recent years, high arsenic (As) levels of about 300 µg/L have been reported around the gold mining areas of Geita and Mara regions within the Lake Victoria basin (LVB) in Tanzania. During a sampling campaign at Geita and Mara, the groundwater and surface water samples revealed the presence of high As concentrations as well as Fe and sulfide. READ MORE

  5. 3. Electropermutation assisted by ion-exchange textile : removal of nitrate from drinking water

    Author : Carl-Ola Danielsson; Anders Dahlkild; Mårten Behm; Anna Velin; Gerald Pourcelly; KTH; []

    Abstract : Increased levels of nitrate in ground water have made many wells unsuitable as sources for drinking water. In this thesis an ion-exchang eassisted electromembrane process, suitable for nitrate removal, is investigated both theoretically and experimentally. READ MORE

  6. 4. Anammox-based systems for nitrogen removal from mainstream municipal wastewater

    Author : Andriy Malovanyy; Elzbieta Plaza; Adriano Joss; KTH; []

    Abstract : Nitrogen removal from municipal wastewater with the application of deammonification process offers an operational cost reduction, especially if it is combined with a maximal use of organic content of wastewater for biogas production. In this thesis, two approaches for integration of the deammonification process into the municipal wastewater treatment scheme were studied. READ MORE
