    Sammanfattning : Integrating thermal energy storage (TES) technologies to a process enables storing and releasing thermal energy on demand. Depending on the implementation, this may lead to economic and ecological improvements, e.g. by shifting the peak demand to off-peak hours or by increasing the share of utilized renewable energy.

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Reducing eutrophication in our surface waters caused by nutrient overload is of importance in order to ensure an environment in ecological balance for future generations. Municipal wastewater treatment plants are the main point source of nutrients emissions. LÄS MER

  4. 4. Sustainable Water Quality Monitoring for Developing Countries in the Context of Mining : Monitoring systems and modelling

    Detta är en avhandling från Water Resources Engineering, Lund University

    Författare :Clemencio Nhantumbo; Lund University.; Lunds universitet.; [2017-05-07]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Water Quality; Monitoring systems; Modelling; pH and alkalinity;

    Sammanfattning : Mining, seen as a source of revenue in most developing countries, threatens seriously the environment. Mining impacts the water quality and one of the main problems of mining is acid mine drainage. Low pH and high concentration of heavy metals characterize acid mine drainage. LÄS MER

  5. 5. Microalgae at wastewater treatment in cold climate

    Detta är en avhandling från Luleå : Univ

    Författare :Erik Grönlund; Mittuniversitetet.; [2002]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Other technology Environmental engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Miljöteknik; Microalgae wastewater treatment cold climate sustainability; VA-teknik; Urban Water Engineering;

    Sammanfattning : The thesis concludes that microalgae may improve wastewater treatment in ponds in cold climate, from a treatment perspective as well as a sustainability perspective. A literature review revealed that the microalgae biomass produced may find economic use, depending on what species will come to dominate, since there are many possible products from microalgae biomass.
