1. Innovative treatment technologies for PFAS-contaminated water - Utilizing foam partitioning and exploring electrochemical oxidation
Sammanfattning : The presence of per- and polyfluoroalkyl substances (PFAS) in the aquatic environment has become a global cause for concern. PFAS are persistent anthropogenic chemicals, and certain PFAS are known to be mobile, bioaccumulative and toxic. LÄS MER
2. Aspects of drinking water supply in areas of humic water
Sammanfattning : The thesis investigated several aspects that are important for drinking water supply from waters with high amounts of humic substance (humic water). The results showed that the composition of humic substances is important in their sorption to aquifer material during surface water artificial recharge through infiltration basins to groundwater.

3. (O)ändligt vatten : En studie om hur förskolebarn som kännare engageras i samhälleliga miljöfrågor
Sammanfattning : Syftet med den här avhandlingen i förskoledidaktik är att tillsammans med förskolebarn på olika sätt utforska aktören vatten för att därigenom undersöka former och metoder för engagemang och medverkan i samhälleliga och naturvetenskapliga miljöfrågor. Mer specifikt är syftet att i ett praktiskt utforskande med förskolebarn och vatten – som aktör och mer-än-mänsklig samarbetspartner – undersöka hur eller med vilka metoder det är möjligt att producera ett engagemang, i vilket förskolebarnet är både kännare och kännande, i vår samtids centrala miljöfrågor.

4. Water Supply in Tanzania and Performance of Local Plant Materials in Purification of Turbid Water
Sammanfattning : Water supply services in urban and rural areas of Tanzania were reviewed and specific studies were carried out on water supply and on purification of turbid water sources using locally available plant materials in rural villages of Singida Rural District. The review showed that large proportions of urban and rural populations in Tanzania face acute water supply problems mainly due to poor planning, implementation and management of water supply projects, including an inability to address social, technical, operation and maintenance and financial issues.

5. Assessment of stormwater and snowmelt quality based on water management priorities and the consequent water quality parameters
Sammanfattning : Stormwater and snowmelt pollution contributes to degradation of quality of the receiving waters. For assessing such impacts, it is effective to focus on specific causes of degradation, as done in this study of the quality of stormwater and snowmelt discharges into the receiving waters serving for supply of raw drinking water and water-based recreation.
