   Sammanfattning : Conventional end-of-pipe solutions for wastewater treatment have been criticized from a sustainable view-point, in particular regarding recycling of nutrients. The integration of hydroponic cultivation into a wastewater treatment system has been proposed as an ecological alternative, where nutrients can be removed from the wastewater through plant uptake; however, cultivation of plants in a temperate climate, such as Sweden, implies that additional energy is needed during the colder and darker period.

4. 38. Aerosol-water interaction at sub and super-saturated regimes : From small scale molecular mechanisms to large scale atmospheric models

   Författare :Narges Rastak; Ilona Riipinen; Maria Kanakidou; Stockholms universitet; []

   Sammanfattning : The term “atmospheric aerosol” refers to solid or liquid particles suspended in the atmosphere. Atmospheric aerosols influence the Earth’s energy budget directly by scattering and absorbing radiation (known as the direct aerosol effect) and indirectly by acting as cloud condensation nuclei (CCN) and ice nucleating particles and thereby modifying cloud properties (known as the indirect aerosol effect).

7. 40. 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. LÄS MER
