21. On the interactions of ions and odor molecules with nanomaterials in water and synthetic urine
Sammanfattning : Towards the quest of finding materials to be used as adsorbents in real systems, it is crucial to understand the underlying adsorption processesfully. In many applications, adsorption occurs in biological fluids containing a vast range of ions, organic molecules, and biomolecules. LÄS MER
22. Alkaline Urine Dehydration : how to dry source-separated human urine and recover nutrients?
Sammanfattning : Human urine is a renewable resource from which water, nutrients and energy can be recovered and safely recycled. This thesis presents a novel on-site technology, called alkaline dehydration, for recovering nutrients from source-separated urine. LÄS MER
23. Bladder cancer. Urine tumour markers and hematuria
Sammanfattning : Cancer of the urinary organs is one of the more common cancer forms in Sweden, with bladder cancer as the fourth most common cancer among men, and the seventh most common among women. The bladder cancer incidence is rising with age and is seldom seen before 50 years of age. LÄS MER
24. Safe Nutrient Recovery from Human Urine - System and Hygiene Evaluation of Alkaline Urine Dehydration
Sammanfattning : Only 7% of the world’s wastewater receives tertiary treatment, while the rest is causing eutrophication, hypoxia and climate change through the plant nutrients found in excreta, particularly urine. If managed adequately, urine can be used as a fertiliser because it contains the same nutrients as the fertilisers used to produce food world-wide. LÄS MER
25. Treatment technologies for human faeces and urine
Sammanfattning : This thesis examines simple, cheap, environmentally friendly and resource efficient technologies for the treatment of source-separated human faeces and urine to enable safe recycling of their plant nutrients for plant production in developing countries. Composting of faeces-to-food waste (F:FW) in wet weight mix ratios of 1:0, 3:1 and 1:1 was studied in 78 L reactors insulated by 25 mm styrofoam; and of F:FW in wet volume/weight ratios of 1:0, 1:1 and 1:3 in 216 L reactors insulated by 75 mm styrofoam.
