1. Faradaic Reactions in Capacitive Deionization : A Comparison of Desalination Performance in Flow-through Cell Architectures
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : 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.

2. Fluctuating pH simulating natural variability modulates larval growth for Strongylocentrotus droebachiensis
Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskapSammanfattning : 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.

3. Optimisation of an ultrafiltration unit on a bench-scale pilot plant - A comparison between carbon and sand filtrate
Master-uppsats, KTH/KemiteknikSammanfattning : Kommunalförbundet Norrvatten är en av Sveriges största producenter av dricksvatten och förser över 50 miljoner vatten till över 700 000 invånare i norra Stockholm. Vattnet är renat i Görvälnverket som har sedan år 2016 planlagt en expansion av verkets kapacitet och kvalité. LÄS MER
4. Analysis of the water quality dynamics of Lake Vomb; Interactions between water quality profile and cyanobacterial bloom in a eutrophic lake in Sweden
Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresursläraSammanfattning : 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. LÄS MER
5. Storage of poultry manure in containers : changes in physiochemical parameters and survival of intestinal bacteria
Master-uppsats, SLU/Dept. of Animal Nutrition and ManagementSammanfattning : 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
