  1. 1. Faradaic Reactions in Capacitive Deionization : A Comparison of Desalination Performance in Flow-through Cell Architectures

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : John Bradley; Miranda Carlström; [2023]
    Keywords : Capacitive deionization; Faradaic reactions; Flow-through CDI; Upstream anode; Downstream anode; Desalination Performance; pH fluctuations;

    Abstract : Capacitive Deionization (CDI) is an energy-efficient desalination technology that utilizes an electric field to extract ions from water. Flow-through CDI systems show potential for superior desalination performance compared to traditional flow-by CDI; however, they face the challenge of increased occurrence of Faradaic reactions, leading to undesired by-products and reduced energy efficiency.

  3. 2. Fluctuating pH simulating natural variability modulates larval growth for Strongylocentrotus droebachiensis

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Bryn Anderson; [2022-08-05]
    Keywords : ocean acidification; global change; sea urchin; duration; intensity; biological response;

    Abstract : Ocean acidification (OA) is the downward trend of ocean pH mainly resulting from the absorption of carbon dioxide (CO2) emissions from anthropogenic sources. pH of the open ocean is expected to drop to 7.7 by the end of the century. READ MORE

  5. 4. Analysis of the water quality dynamics of Lake Vomb; Interactions between water quality profile and cyanobacterial bloom in a eutrophic lake in Sweden

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Wiebke Coenen; [2022]
    Keywords : Vombsj¨on; Lake profile; Cyanobacteria; Drinking water; Random Forest; Technology and Engineering;

    Abstract : Lake Vomb, located in Sk˚ane, Sweden, provides water for groundwater infiltration, used for the drinking water supply of several municipalities, including Malm¨o. The lake is in a bad ecological condition with intense algae blooms during summer. Cyanobacteria dominate mentioned blooms in 2021 posing the threat of releasing cyanotoxins. READ MORE

  6. 5. 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
