2. 1. Extending Access : Perspectives on Business Model Innovation in Water and Sanitation Service Provision

   Author : Caroline Jennings Saul; Anders Gustafsson; Nina Veflen; Karlstads universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business Innovation; Water business; WASH; Sanitation; Digitalization; Base of the pyramid; Business Administration; Företagsekonomi;

   Abstract : Many organizations are attempting to improve the well-being of people living in poverty, whether it be philanthropic, through offering transformative services, or buying into the doing well by doing good ethos of corporate Base of the Pyramid (BoP) strategies. Some of these efforts are being directed towards extending access to safely managed water and sanitation services to everyone. READ MORE

4. 2. Colloidal Organic Pollutants in Road Runoff: Sources, Emissions and Effective Treatment Technologies

   Author : Anna Markiewicz; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; organic pollutants; nanoparticles; stormwater; sorption filters; road dust; emulsions; washwater; vehicle wash; road runoff; microparticles; sweepsand; colloids; street sweeping;

   Abstract : Thousands of organic substances circulate in our society and are diffusely emitted through traffic, combustion and leaching from constructions and building materials into the urban environment. The research in this PhD thesis focuses on road runoff as the highest concentrations of pollutants are frequently found in runoff from areas with high traffic intensity. READ MORE

5. 3. The Impact of Dissolved Matter on Fiberline Processes

   Author : Caroline Wilke; Ulf Germgård; Niclas Andersson; Juha Fiskari; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bleach plant control; Carbonate; Carryover; Chlorine dioxide bleaching; COD; Dissolved lignin; Dissolved matter; Fiberline control; Filtrate; Hexenuronic acid; Hydrogen peroxide bleaching; Kappa number; Oxygen delignification; Wash loss; Chemical Engineering; Kemiteknik;

   Abstract : The impact of dissolved matter on the performance of four fiberline process stages was investigated: oxygen delignification, hot acid treatment, chlorine dioxide bleaching, and hydrogen peroxide reinforced alkaline extraction. In particular the impact on delignification due to dissolved lignin was studied. READ MORE

6. 4. Characterization of soot in air and rain over southern Asia

   Author : Erik J. Engström; Caroline Leck; Henning Rodhe; Paolo Laj; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; soot; black carbon; atmospheric concentration; light absorption; wet deposition; scavenging; wash-out ratio; South-Asia.; Atmosphere and hydrosphere sciences; Atmosfärs- och hydrosfärsvetenskap;

   Abstract : Filter-based optical measurements of light absorbing particulate matter at awavelength of about 550 nm, here referred to as soot, in air and rainwaterhave been performed during the period from 1st June 2005 to 31th May 2009at Godavari in Nepal, Sinhagad in India and Hanimaadhoo in The Maldives.A method for determination of water-insoluble light absorbing matter inrainwater has been developed.

7. 5. Microbial Ecology of Granular Sludge

   Author : Raquel Liebana; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-throughput DNA analysis; sequencing batch reactors; granular structure; wash-out dynamics; aerobic granular sludge; disturbance; fluorescence in-situ hybridization; microbial community dynamics; granulation; reproducibility;

   Abstract : Granular sludge is an efficient and compact biofilm process for wastewater treatment. Despite the well-established methods for granule cultivation, the ecological processes underpinning the microbial community assembly during granulation are poorly understood. READ MORE
