1. Uncharted Waters : Non-target analysis of disinfection by-products in drinking water
Sammanfattning : Disinfection by-products (DBPs) are potentially toxic compounds formed when drinking water is treated with disinfectants, such as chlorine or chloramine. A large proportion of the exposure to DBPs is still unknown and the health risks observed through epidemiological studies cannot be explained by DBPs known today. LÄS MER
2. Catalytic Water Production from First-Principles Calculations
Sammanfattning : The main subject of this thesis is the catalytic water production reaction on metal surfaces. This reaction is of great current interest due to its importance in fuel cells, a clean and efficient way to convert chemical energy into electrical. LÄS MER
3. Relaxation dynamics of perturbed water and other H-bonded liquids
Sammanfattning : Most liquids can be supercooled below its melting point where the dynamics dramatically slows down with decreasing temperature until the material appears solid on the experimental time scale and becomes stuck in an out-of-equilibrium configuration, a glass. Water, one of the most abundant substances on earth, is no exception. LÄS MER
4. Hazardous substances in wastewater systems : a delicate issue for wastewater management
Sammanfattning : Many substances derived from human activity end up in wastewater systems at some point. A large number of different substances - up to 30,000 - are present in wastewater. Some of them are valuable, such as nitrogen and phosphorus, but there are also hazardous substances such as heavy metals and anthropogenic organic substances. LÄS MER
5. Biofiltration of odorous gas emissions
Sammanfattning : Biofiltration has shown its potential as an interesting treatment alternative for contaminated gas streams. Unlike conventional technologies, such as adsorption, scrubbers, and incineration, biofiltration offers effective pollution control at relatively low capital and operating costs, and without the generation of secondary pollution that may require subsequent treatment.
