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

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Sara Schützer; [2022]
    Keywords : ;

    Abstract : 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). READ MORE

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

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Homayoon Davam; [2022]
    Keywords : Enterobacteriaceae; Salmonella; composting; straw; litter decontamination; chicken manure;

    Abstract : 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. READ MORE

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

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

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

    Abstract : 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

    University essay from Lunds universitet/Kemiteknik (CI)

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

    Abstract : 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. READ MORE

  6. 5. Causes and impact of surface water pollution in Addis Ababa, Ethiopia

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Malin Eriksson; Jonathan Sigvant; [2019]
    Keywords : Akaki river; E. coli; health risk; interview study; irrigation; physico-chemical parameters; water samples; Akaki; E. coli; fysikalisk-kemiska parametrar; hälsorisker; intervjustudie; vattenprover;

    Abstract : Surface water is globally becoming more and more a scarce resource, and in Addis Ababa the capital of Ethiopia, river water quality has been degraded due to anthropological forcing for many years. Therefore, the study objective was to investigate causes and impact of surface water pollution in Kebena and Great Akaki rivers. READ MORE
