1. Impact of Drinking Water Treatment and Pipe Biofilms on Bacterial Dynamics in the Distribution System
Abstract : This thesis addresses drinking water quality and microbiology in full-scale drinking water distribution systems (DWDSs). It examines how UV irradiation and slow sand filters (SSFs) alter the water bacteriome, and how the biofilm in the DWDS affects the drinking water quality. READ MORE

2. Tracking changes in dissolved natural organic matter composition : evaluating drinking water production using optical and molecular level tools
Abstract : 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. READ MORE

3. Endocrine disrupting compounds in effluent waters : Chemical analysis to evaluate exposure of fish
Abstract : The aim of this thesis was to investigate if endocrine disruption related to the release of estrogenic and/or androgenic substances via sewage treatment plant and pulp mill effluents is significant in Swedish waters. Chemical analysis of bile fluid in combination with measurement of biomarkers was used for the evaluation of internal exposure and effects in fish. READ MORE

4. Towards Energy-Efficient Drinking Water Production using Biomimicry
Abstract : 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. READ MORE

5. Biofilms and microbial barriers in drinking water treatment and distribution
Abstract : The primary objective of conventional drinking water treatment and distribution is to deliver to the consumer water that is both aesthetically pleasing and does not constitute a human health risk. To achieve this, water utilities employ a range of physical (i.e. sand and membrane filtration) and chemical (i. READ MORE
