2. 1. Towards Energy-Efficient Drinking Water Production using Biomimicry

   Author : Simon Isaksson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Filter; Membrane Protein; Supported Lipid Bilayer; Drinking Water; Water Treatment; Silica; Aquaporin; Liposome; Biomimicry;

   Abstract : Water is a prerequisite for life and we therefore need pure drinking water to survive. Yet there are more than half a billion people that do not have access to pure drinking water. Water treatment can be performed in many different ways, one of the most commonly used being filtration. READ MORE

4. 2. Time-resolved Structural and Mechanistic Studies of Water Oxidation in Photosystem II : water here, water there, water everywhere

   Author : Casper de Lichtenberg; Johannes Messinger; Wolfgang P. Schröder; Holger Dau; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Oxygenic Photosynthesis; Photosystem II; TR-MIMS; isotope exchange; EPR; EDNMR; water splitting; water oxidation;

   Abstract : Oxygenic photosynthesis is undisputedly one of the most important chemical processes for human life on earth as it not only fills the atmosphere with the oxygen that we need to breathe, but also sustains the accumulation of biomass, which is not only used as nourishment but is also present in almost every aspect of our lives as building material, textiles in clothes and furniture, or even as living decorations to name a few.The photosynthetic water-splitting mechanism is catalyzed by a water:plastoquinone oxido-reductase by the name of photosystem II (PSII), which is embedded in the thylakoid membranes of plants, algae and cyanobacteria.

5. 3. Advancing the Implementation of Protective Measures for Drinking Water Sources in Sweden

   Author : Nadine Gärtner; Chalmers tekniska högskola; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; water protection; mitigation measures; spatial planning; groundwater; surface water; drinking water; risk assessment;

   Abstract : The world’s drinking water sources are under growing pressure due to human activities, including infrastructure projects, agriculture, climate change, and the ever-increasing need for freshwater. Although there is a strong call to protect our source waters instead of increasing treatment efficiency at the drinking water treatment plant, the extent of protection measures is often hotly debated.

6. 4. PFAS in the water supply: source water contamination

   Author : Dauren Mussabek; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; source water; drinking water; per- and polyfluoroalkyl substances; PFAS; AFFF; UV treatment;

   Abstract : Water contamination with per- and polyfluoroalkyl substances (PFAS) is a serious problem for water suppliers in many regions. Due to persistence of the substances and a complex distribution mechanism, PFAS can have an adverse impact on water quality. READ MORE

7. 5. Sustainable and Safe Use of Non-conventional Waters -Reclaimed Water and Desalinated Water

   Author : Shuang Liu; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Water reuse; Desalination; Strategy; Water security; Guidelines; Policy; Microbial risk assessment;

   Abstract : Fresh water scarcity, pollution and an uneven distribution have caused an increasingly serious global water crisis. One of the most widely adopted response strategies is the exploitation and use of non-conventional water sources. READ MORE
