  1. 1. Separating Acetate, Formate and MSA from natural samples using ion chromatography

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Alexandra Drake; [2013]
    Nyckelord :short organic acids; acetate; formate; MSA; ion chromatography; climate; Lomonosovfonna; Svalbard; Antarctica;

    Sammanfattning : Anjoner från de tre korta organiska syrorna: acetat, format och MSA är intressanta att mäta då de kan användas för olika sorters miljöstudier. Jonkromatografen vid Institutionen för Geovetenskaper kan för närvarande inte skilja på dessa tre ämnen, därför utvecklades sex nya metoder i detta projekt för att lösa problemet. LÄS MER

  2. 2. Ground Water and Surface Water Influence on the Water Quality in the Antequera River basin, Bolivia : A Minor Field Study

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

  4. 4. Hydrodynamic modelling and estimation of exchange rates for Bardawil Lagoon, Egypt. An investigation of governing forces and physical processes using numerical models.

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Jonas Linnersund; Erik Mårtensson; [2008]
    Nyckelord :Fysisk geografi; climatology; cartography; Environmental studies; Miljöstudier; wind; water balance; tide; sediment transport; salt balance; renewal time; net intertidal volume; finite element; internal circulation; ADCIRC; CMS-Flow; Bardawil Lagoon; Physical geography; pedology; geomorphology; geomorfologi; marklära; kartografi; klimatologi; Technological sciences; Teknik; Earth and Environmental Sciences; Technology and Engineering;

    Sammanfattning : Bardawil Lagoon, a natural lagoon located on the northern coast of the Sinai Peninsula, Egypt, there are three inlets of which two are man-made connecting the lagoon with the Mediterranean Sea. The inlets are subjected to changes in morphology, due to sediment transport, over time and this may lead to degrees of closure of either inlet. LÄS MER

  5. 5. Evaluation of using fine grain size Polonite® as sorbent for retaining phosphorus from wastewater.

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Carl Nelin Jensen; [2008]
    Nyckelord :offshore technology; hydraulic engineering; Civil engineering; Miljöstudier; Environmental studies; Recycling of sorbent and nutrient; Polonite®; Wastewater treatment; Phosphorus reduction; soil mechanics; Väg- och vattenbyggnadsteknik; Earth and Environmental Sciences; Technology and Engineering;

    Sammanfattning : To avoid eutrofication and excessive algal bloms it is necessary to reduce the phosphorus contents in wastewater. Previous wastewater treatment systems often have a good process for phosphorus reduction but in general not the ability to recycle the material and phosphorus for further utilisation after its use in wastewater treatment.
