1. 1. Evaluation of The Viral Reduction Potential using Ultrafiltration Membranes in the Drinking Water Treatment Process at Norrvatten

   University essay from KTH/Industriell bioteknologi

   Author : Emma Eriksson; [2023]
   Keywords : Microbiological barrier; Ultrafiltration; NanoCeram filter; Drinking Water; Raw Water; Mikrobiologisk barriär; Ultrafiltering; NanoCeram filter; Dricksvatten; Råvatten;

   Abstract : En pilotanläggning för ultrafiltering testas nu i Norrvattens reningsprocess för att undersöka ifall den kan användas som en tredje mikrobiologisk barriär i reningsprocessen. Målet med detta projekt är att testa membranets kapacitet att filtrera bort viruspartiklar men även membranet generella reduktionsförmåga för andra mikrobiologiska och kemiska kontamineringar.

3. 2. Spatial patterns of Dissolved Organic Matter in Swedish Surface Waters

   University essay from SLU/Dept. of Aquatic Sciences and Assessment

   Author : Anna Lackner; [2022]
   Keywords : Dissolved Organic Matter; Brownification; Digital Mapping; Soil Moisture; Stream Length;

   Abstract : Dissolved organic matter (DOM) in surface water has been widely studied, in part due to its significance for aquatic ecology and drinking water quality. Across Sweden, increases in the total organic carbon (TOC) concentrations and color of surface waters, known as brownification, were noted in the decades before and after year 2000, though recent analysis has found widespread DOM increase to have ceased after 2010.

4. 3. Modelling the Effects of Climate Change on Future DOC Export to Lake Mälaren Using a Generalized Watershed Loading Functions (GWLF) Model

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Klara Lindqvist; [2022]
   Keywords : Hydrology; DOC; browning; climate change; drinking water production; Mälaren; Hydrologi; DOC; brunifiering; klimatförändringar; dricksvattenproduktion; Mälaren;

   Abstract : Browning of boreal freshwaters due to an increased export of terrestrial dissolved organic carbon (DOC) has been observed for some decennia. Drivers include recovery from acid deposition and changing climate and land cover. READ MORE

5. 4. Closing the loop of human waste: can eco-innovation be the key? Findings from the case study of the LooPi urinal

   University essay from Lunds universitet/Internationella miljöinstitutet

   Author : Maricruz Vargas Esquivel; [2022]
   Keywords : eco-innovation; eco-toilet; wastewater reuse; circular economy; Vienna; Earth and Environmental Sciences;

   Abstract : The Circular Economy (CE) primary goal is to be capable of "closing the loops" in processes by changing the idea of resources and waste. Eco-innovation ("the introduction of any new or significantly improved product (good or service), process, organizational change or marketing solution that reduces the use of natural resources (including materials, energy, water, and land)" could be a way to encourage industries to develop more solutions with "closed-loop" systems.

6. 5. Hydrodynamic modelling of fate and transport of natural organic matter and per- and polyfluoroalkyl substances in Lake Ekoln

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Frida Ekman; [2021]
   Keywords : Ekoln; Natural organic matter NOM ; Total organic matter TOC ; Colour; degradation; sedimentation; photooxidation; PFAS; MIKE 3 FM; Ekoln; naturligt organiskt material NOM ; totalt organiskt kol TOC ; färg; nedbrytning; sedimentation; foto-oxidation; PFAS; MIKE 3 FM;

   Abstract : Societies are facing great challenges with obtaining a good quality and quantity of drinking water in the context of climate change. Increases in natural organic matter (NOM) and per- and polyfluoroalkyl substances (PFAS) have been observed in lakes and drinking water the past years, which is of great concern for water treatment plants in Sweden.
