2. 1. Urine separating wastewater systems : experiences of design and nitrogen conservation

   Author : Erica Johansson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

   Abstract : Urine separating (US) wastewater systems, where urine is collected and used as a fertiliser, may be a strategy to achieve a high degree of nutrient recycling from human waste to agriculture. The Swedish experiences of US systems show that the design of the toilets and the sewers are of great importance to achieve a working system. READ MORE

4. 2. Nutrient recovery from waste streams through struvite formation

   Author : Maryam Latifian; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; struvite; nutrient; phosphorus; nitrogen; wastewater treatment; anaerobic digestion; urine;

   Abstract : Eutrophication or the nutrient enrichment of water bodies, typically by nitrogen and phosphorus has adversely affected the aquatic life and the quality of water. Governments have been forced to take actions in order to reduce the release of these nutrients into the environment. READ MORE

   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainable sanitation; sand filter; phosphorus filter; package plant; cold climate; treatment process; system analysis; sustainability indicators; decentralization; centralization; historical development; on-site; resource recovery; source separation; source-separating systems; blackwater; urine; greywater; hållbarthetsanalys; små avlopp system; enskilda avlopp; markbädd; minireningsverk; kallt klimat; systemanalys; fosforfälla; fosforfilter; indikator; urin sortering; svartvatten; toalettvatten; gråvatten; BDT; VA-teknik; Urban Water Engineering;

   Abstract : Current socio-technical wastewater system paradigms are being challenged by emerging global issues such as climate change, environmental degradation and scarcity of resources. Thus, exploration of innovative new urban water management solutions is required that enable closure of resource loops. READ MORE

6. 4. Adsorption and reclamation of wastewater nitrogen and the value of human urine as a nitrogen fertiliser

   Author : Annelie Hedström; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

   Abstract : Ammonium adsorption and ammonium ion exchange technique are possible alternatives for ammonium reclamation at conventional wastewater treatment plants. There are a few ion exchange applications that have been suggested for nitrogen reclamation, which can be further developed. READ MORE

7. 5. Antibacterial effects of nitrite in urine

   Author : Stefan Carlsson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Nitrite; nitrate; nitric oxide; urinary tract infection; catheter-associated urinary tract infection; antimicrobial; Escherichia coli.;

   Abstract : Urinary tract infections (UTI`s) are among the most common conditions causing individuals to seek medical care. In addition, catheter-associated infections account for most of the hospital-acquired UTI´s and is also a major source of resistant nosocomial pathogens. READ MORE
