  1. 11. Variability and regulation of the planktonic respiratory quotient in a eutrophic lake (Lake Vombsjön) in summer 2016

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Karla Münzner; [2017]
    Keywords : Physical geography and ecosystem analysis; biogeochemistry; bacterioplankton respiration; eutrophic lake; carbon cycling; Lake Vombsjön; Earth and Environmental Sciences;

    Abstract : Bacterial respiration and biomass growth are important processes for carbon cycling in freshwater ecosystems and bacterial respiration is often quantified from measured O2 concentrations by using a respiratory quotient (RQ=O2 consumed to produce CO2, in moles) of 1. Recent studies have shown, however, that RQs can vary a lot in different aquatic ecosystems (0. READ MORE

  3. 12. Rhizosphere Priming and Methane Oxidation in Agricultural Soil - Effect of Land Use on Atmospheric Concentrations of CO2 and CH4 and Climate Change

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Esben Øster Mortensen; [2017]
    Keywords : The Priming Effect; Rhizosphere; Methane Oxidation; Land Use; Agriculture; Soil Ecology; Microorganisms; Climate Change; Atmospheric concentrations of CO2 and CH4.; Earth and Environmental Sciences; Biology and Life Sciences; Agriculture and Food Sciences;

    Abstract : Rhizosphere interactions have high influence on the fluxes of carbon to and from terrestrial ecosystems. One very important part of the rhizosphere interactions is the rhizosphere priming effect (RPE) which is defined as changes in the decomposition rate of soil organic matter (SOM) in response to labile organic carbon input from plant roots.

  4. 13. Investigation of the combustion behavior in a fluidized reactor with oxygen carriers as bed material

    University essay from KTH/Energi- och ugnsteknik

    Author : Carl Kajnäs; [2016]
    Keywords : Bed materials; Fluidized bed combustion; Gaseous fuels; Oxygen carrier aided combustion; Oxygen carriers.;

    Abstract : The behavior of using oxygen carriers as bed material in a fluidized bed combustion was investigated in this work when methane, air and carbon monoxide, air are used as fluidizing gases. More specifically, conversion rate, unsteadiness and gas composition was investigated and it was found that the conversion rate of carbon monoxide and methane are higher when oxygen carriers are used as bed material compared to silica sand and that the highest conversion rate was for oxygen carriers with high oxygen transport capacity and high reactivity towards the gaseous fuel.

  5. 14. Mainstream deammonification reac-tor at low DO values and employing granular biomass.

    University essay from KTH/Mark- och vattenteknik

    Author : Marco Salmistraro; [2015]
    Keywords : ANAMMOX; Deammonification; Dissolved oxygen control; Granu-lar biomass; Mainstream municipal wastewater treatment; Partial nitrification;

    Abstract : Nitrogen removal from wastewater has been exstensively addressed by scientific literature in recent years; one of the most widely implemented technologies consists of the combination of partial nitritation and anaerobic ammonium oxidation (ANAMMOX). Compared to traditional nitrification and denitrification techniques such solution eliminates the requirement for an external carbon source and allows for a reduced production of excess sludge; furthermore, it brings down the costs associated to aeration by 60-90% and the emissions of CO2 by 90%.

  6. 15. Upgrading of Landfill Gas with Household Waste Slag

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Seyedhani Sadatgol; [2015]
    Keywords : Landfill gas; Hydrogen sulfide; Bottom Ash; Carbonation; Slag;

    Abstract : Modern landfills produce landfill gas, LFG, on a smaller scale and with limited content of degradable organic materials in the waste. The waste deposit in the Sofielund landfill began in 2005 and the final coverage is not yet commenced. The landfill waste must contain up to 10% decomposable organic materials at most. READ MORE
