3. 12. Bark and charcoal filters for greywater treatment : pollutant removal and recycling opportunities

   Författare :Sahar Dalahmeh; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : Water scarcity, inappropriate sanitation and wastewater pollution are critically important global issues. Greywater is a sustainable water source for recycling, so this thesis examined simple, robust, low-cost alternatives for on-site treatment of greywater to irrigation water quality. LÄS MER

4. 13. On-site sanitation systems - An integrated assessment of treatment efficiency and sustainability

   Författare :Brenda Vidal; Annelie Hedström; Inga Herrmann; Arve Heistad; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; small-scale; sand filter; phosphorus filter; package plant; blackwater; greywater; urine diversion; multi-criteria; composite sample; VA-teknik; Urban Water Engineering;

   Sammanfattning : Small on-site sanitation systems for wastewater collection and treatment are prevalent in suburban and rural areas in many countries. However, these systems often underperform, causing potential impact to the receiving waters and increasing the risks to public health, thus hindering the overall sustainability of the systems.

   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ekonomisk teori; Nationalekonomi; ekonometri; economic policy; economic systems; economic theory; econometrics; Economics; Discrete Choice; Welfare; Child Health; Water and Sanitation; Household Demand; ekonomiska system; ekonomisk politik; Public health; epidemiology; Folkhälsa; epidemiologi; Environmental health; Miljömedicin;

   Sammanfattning : This thesis focuses on different aspects of household demand, and the determinants of demand, for water and sanitation related inputs fundamental to the households' well-being, i.e. drinking water and toilet facilities. The thesis consists of five chapters, one introductory chapter and four self-contained, essentially empirical, studies. LÄS MER

7. 15. Urban wastewater systems: From disposal to reuse. A study of different systems with focus on water and nutrients flows

   Författare :Justyna Czemiel Berndtsson; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Storm Water; Urban; Wastewater; Civil engineering; offshore technology; hydraulic engineering; Väg- och vattenbyggnadsteknik; soil mechanics; pollution control; Environmental technology; Miljöteknik; kontroll av utsläpp; Nutrients;

   Sammanfattning : Urban wastewater systems are currently exposed to a major rethink dictated by new demands on resource management. It is postulated that next to providing efficient sanitation (preventing spread of pathogenic microorganisms) these systems should support resource reuse. LÄS MER
