1. 16. Investigation of the redox-conditions in the Nam Du well field, Hanoi, Vietnam, and their implications for mobilisation of arsenic

   L3-uppsats, SLU/Dept. of Soil Sciences

   Författare :Johanna Moreskog; [2007]
   Nyckelord :arsenic mobilisation; redox potential; wells; Ha Noi; Viet Nam;

   Sammanfattning : In 2005, a new well field along the Red River started pumping groundwater for production of drinking water in the Nam Du area south of Hanoi, Vietnam. Elevated concentrations of ammonium have been a well-known problem in the southern part of Hanoi area, but recently elevated concentrations of arsenic in the groundwater has also been of concern.

3. 17. Avskiljning av ammoniumkväve och fosfatfosfor i reaktiva filtermaterial : skak- och kolonnförsök

   Uppsats för yrkesexamina på avancerad nivå, Institutionen för geovetenskaper

   Författare :Katarina Poll; [2005]
   Nyckelord :sorption; removal; precipitation; reactive filters; wastewater;

   Sammanfattning : In Sweden more than 400 000 private households have not yet sufficient wastewater purification. These effluent is considered as an increasing problem and many onsite purification methods have been studied. In this investigation, the method of reactive bed filters have been tested by column and batch experiments. LÄS MER
