1. Anaerobic digestion in the kraft pulp and paper industry : Challenges and possibilities for implementation
Sammanfattning : The pulp and paper industry is a large producer of wastewater and sludge, putting high pressure on waste treatment. In addition, more rigorous environmental legislation for pollution control and demands to increase the use of renewable energy have put further pressure on the pulp and paper industry’s waste treatment, where anaerobic digestion (AD) and the production of methane could pose a solution.

2. Wastewater treatment in constructed wetlands : Effects of vegetation, hydraulics and data analysis methods
Sammanfattning : Degradation of water resources has become one of the most pressing global concerns currently facing mankind. Constructed Wetlands (CWs) represent a concept to combat deterioration of water resources by acting as buffers between wastewater and receiving water bodies. LÄS MER
3. Constructed Wetlands and Deconstructed Discourses : Greenhouse gas fluxes and discourses on purifying capacities
Sammanfattning : This thesis is a study within the sciences ofconstructed wetlands. It has two sections. Section one is a natural scienrific study ofgas fluxes from construcred wetlands and section two is an analysis ofhow natural sciences describe constructed wetlands. LÄS MER
4. Removal of Natural Organic Matter and Control of Trihalomethanes Formation in Water Treatment
Sammanfattning : Volcanic ash, pumice and Moringa oleifera (M. oleifera) were investigated as indigenous materials for removal of natural organic matter (NOM) at Kampala and Masaka water treatment plants in Uganda. LÄS MER
5. Antimicrobial materials from cellulose using environmentally friendly techniques
Sammanfattning : The transition to a more biobased society introduces both new opportunities and new challenges as we replace nonrenewable materials with renewable alternatives. One important challenge will be to control microbial growth on materials, both to protect the materials from biological degradation and to prevent the spread of infections and toxins that can cause illness.
