1. Sensor-based Methods for Improved Understanding of Biological Water Treatment
Sammanfattning : .... LÄS MER
2. Partial renewal of granular activated carbon filters for improved drinking water treatment
Sammanfattning : Drinking water is widely collected from surface water sources. In these water sources, both the quantity and quality of natural organic matter (NOM) have been affected around the world during the last decades, especially in Northern Europe and North America. LÄS MER
3. Coagulant Protein from plant materials: Potential Water Treatment Agent
Sammanfattning : Access to fresh water is a human right, yet more than 780 million people, especially in rural areas, rely on unimproved sources and the need for finding ways of treating water is crucial. Although the use of natural coagulant protein in drinking water treatment has been discussed for a long time, the method is still not in practice, probably due to availability of material and limited knowledge.

4. Assessing and optimizing biofilter performance in drinking water treatment
Sammanfattning : Biological filtration is a widely used treatment barrier in drinking water treatment plants to ensure the biological stability of treated water in distribution systems. Biofilters remove particulate and dissolved organic matter (DOM) and biodegradable organic matter from water. LÄS MER
5. Biogeochemical Processes in Denitrifying Woodchip Bioreactors and their Application in the Mining Industry
Sammanfattning : This thesis evaluates passive denitrifying woodchip bioreactors (DWBs) for the removal of nitrate (NO3-) in neutral pH mine drainage, where water is passed through a carbon-rich porous matrix (e.g. woodchips) for the reduction of NO3- to nitrogen gas. LÄS MER
