1. Towards Energy-Efficient Drinking Water Production using Biomimicry
Sammanfattning : 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. LÄS MER
2. Sustainable and Safe Use of Non-conventional Waters -Reclaimed Water and Desalinated Water
Sammanfattning : 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. LÄS MER
3. Evaluation of Modern Irrigation Techniques with Brackish Water
Sammanfattning : Modern irrigation techniques are becoming increasingly important in water-scarce countries especially in arid and semiarid regions. Higher crop production and better water use efficiency are usually achieved by drip irrigation as compared to other irrigation methods. LÄS MER
4. 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.

5. Fresh Perspectives on the Assessment of Sewage Sludge Management
Sammanfattning : Sewage sludge management and its role in closing nutrient cycles have received considerable attention in recent years. This thesis quantified phosphorus flows in Gothenburg, Sweden, under current and possible future waste management practices, and aimed to improve the assessment of wastewater and sludge management from an environmental and human health perspective through blending risk assessment (RA) and life cycle assessment (LCA).
