    Sammanfattning : För att växter ska växa bra krävs det en mix av olika näringsämnen där de två viktigaste näringsämnena normalt sett är kväve (N) och fosfor (P). Det är viktigt att mixen av olika näringsämnen passar växtens behov samt att näringsämnena är möjliga för växten att ta upp. LÄS MER

  3. 27. THEORETICAL STUDY TO IMPROVE THE ENERGY BALANCE IN WASTEWATER TREATMENT PLANT : Investigation of microalgae photobioreactor in biological treatment step and open algal pond in reject water treatment in Uppsala and Västerås

    Master-uppsats, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Richard Marcin; Matej Mucha; [2015]
    Nyckelord :Energy balance; Wastewater treatment plant; Microalgae; Photobioreactor; Open algal pond;

    Sammanfattning : The self-treatment system of nature cannot handle man-caused high rate water pollution on its own, therefore cleaning in wastewater treatment plant (WWTP) is necessary to avoid eutrophication – excessive enrichment of nature by nutrients. Current technologies applied in WWTPs are old, outdating and highly energy demanding, especially biological treatment step generally requires large amount of energy for aeration of water. LÄS MER

  4. 28. The effect of different carbon sources on reduction of nitrate in effluent from the mining industry : Olika kolkällors inverkan på reduktion av nitrat i processvatten från gruvindustrin

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Hanna Lindberg; [2014]
    Nyckelord :Denitrification; mine effluent; nitrogen; external carbon; sediment;

    Sammanfattning : Mine water effluent contains high levels of nitrogen due to residues from undetonated ammonium- nitrate based explosives. Excess nitrogen in aquatic ecosystems can cause eutrophication. LÄS MER

  5. 29. Effects of the carotenoid inhibiting herbicide diflufenican on the photosynthesis of benthic algae

    Kandidat-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Jelena Rakovic; [2014]
    Nyckelord :benthic algae; freshwater; herbicides; diflufenican; PAM; fluorescence; Lake Erken; photosynthetic efficiency;

    Sammanfattning : Throughout the world, the large-scale use of pesticides in agriculture is an area of concern due to known harmful effects on human and environmental health. Mixtures of different pesticides are found in lakes and streams, where their presence endangers aquatic organisms, like benthic algae, and the ecosystem services they provide. LÄS MER

  7. 30. Flow Cytometry Sensor System Targeting Escherichia Coli as an Indicator of Faecal Contamination of Water Sources

    Master-uppsats, Linköpings universitet/Teknisk biologi; Linköpings universitet/Tekniska högskolan

    Författare :Tobias Benselfelt; [2014]
    Nyckelord :Sensor system; Water quality; Flow cytometry; Faecal contamination; Faecal indicator; Escherichia Coli; Untreated water; Near infrared light; NIR; Antibody; Immunoglobulin; IgY; Alexa Fluor 790; Photomultiplier tube; CMOS; camera.;

    Sammanfattning : Poor water quality is a global health concern affecting one billion people around the world. It is important to monitor water sources in order to maintain the quality of our drinking water and to avoid disease outbreaks. LÄS MER
