  1. 1. Investigating the dynamics controlling dissolved organic matter bioreactivity in agricultural stream water and its link to carbon evasion : A statistical analysis

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Sara Schützer; [2022]
    Nyckelord :;

    Sammanfattning : While streams and rivers emit large quantities of CO2 to the atmosphere, both the mechanisms controlling CO2 evasion as well as the sources of CO2 are still uncertain. One potential source of stream CO2 is in-stream degradation of dissolved organic matter (DOM). LÄS MER

  3. 2. Storage of poultry manure in containers : changes in physiochemical parameters and survival of intestinal bacteria

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Homayoon Davam; [2022]
    Nyckelord :Enterobacteriaceae; Salmonella; composting; straw; litter decontamination; chicken manure;

    Sammanfattning : High nutrient content of chicken litter has made it one of the best organic fertilizers for agricultural land. However, reusing poultry litter in agriculture can be associated with food-borne pathogens such as E.coli, Salmonella and Campylobacter. LÄS MER

  4. 3. Influence of mixing and heat transfer in process scale-up

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Paula Martín Díaz; [2022]
    Nyckelord :Scale-up; mixing; heat transfer; computational fluid dynamics; process simulation;

    Sammanfattning : Process scale-up studies are, generally, non-linear. This basically means that it is not possible to take a chemical process in the laboratory and bring it to a pilot or production plant by simply increasing the quantities of chemicals and the equipment size proportionally.

  5. 4. GAC filter Design Criteria for Wastewater Treatment for Removal of Organic Micropollutants – A Literature Review

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Bhargav Reddy Elavarthi; [2021]
    Nyckelord :micropollutants; activated carbon filtration; empty bed contact time EBCT ; pharmaceuticals; breakthrough curves; adsorption; PFOS; carbon use; water and environmental engineering; Technology and Engineering;

    Sammanfattning : Granular Activated Carbon (GAC) is nowadays suggested as a fourth (quaternary) treatment step at municipal wastewater treatment plants to remove certain chemicals and particularly organic micropollutants (OMPs). This work investigated the different factors that affect the performance of the GAC filter for the removal of micropollutants in a municipal wastewater treatment plant. LÄS MER

  7. 5. Är Bäljane å en möjlig recipient för Nårabs lakvatten?

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Maja Anehagen; [2019]
    Nyckelord :leachate; lakvatten; ytvatten; surface waters; environmental effects; toxicity; heavy metals; Earth and Environmental Sciences;

    Sammanfattning : The aim of this bachelor thesis was to investigate whether or not Bäljane stream is a possible recipient for treated leachate from a Swedish municipal solid waste plant. This report will see how the current environmental status is in the river and how it will be affected in the future if emissions of treated leachate occur. LÄS MER
