1. Towards Energy-Efficient Drinking Water Production using Biomimicry
Sammanfattning : Water is a prerequisite for life and we therefore need pure drinking water to survive. Yet there are more than half a billion people that do not have access to pure drinking water. Water treatment can be performed in many different ways, one of the most commonly used being filtration. LÄS MER
2. Time-resolved Structural and Mechanistic Studies of Water Oxidation in Photosystem II : water here, water there, water everywhere
Sammanfattning : Oxygenic photosynthesis is undisputedly one of the most important chemical processes for human life on earth as it not only fills the atmosphere with the oxygen that we need to breathe, but also sustains the accumulation of biomass, which is not only used as nourishment but is also present in almost every aspect of our lives as building material, textiles in clothes and furniture, or even as living decorations to name a few.The photosynthetic water-splitting mechanism is catalyzed by a water:plastoquinone oxido-reductase by the name of photosystem II (PSII), which is embedded in the thylakoid membranes of plants, algae and cyanobacteria.

3. Tracking changes in dissolved natural organic matter composition : evaluating drinking water production using optical and molecular level tools
Sammanfattning : During the last decades, the abundance of dissolved organic matter (DOM), a complex heterogeneous mixture of organic compounds, has increased in many surface waters in Northern Europe and North America. Surface waters are widely used as raw water sources for drinking water production. LÄS MER
4. Wastewater discharges and microbial variability in a surface water source
Sammanfattning : Planning for drinking-water safety in surface waters includes a systematic assessment of hazards in the catchment, and microbial contamination is considered a major health risk. The aim of this thesis was to identify and characterize microbial hazardous events reported for River Göta älv, Sweden. LÄS MER
5. Access to water : Rights, obligations and the Bangalore situation
Sammanfattning : The city of Bangalore in southern India is undergoing rapid urbanisation and administrative transition. Its growth puts pressure on the available water sources – being mainly the disputed inter-State River Cauvery and the hard-rock aquifers – with ensuing problems of access. LÄS MER
