  2. 21. Assessment of stormwater and snowmelt quality based on water management priorities and the consequent water quality parameters

    Author : Helen Galfi; Maria Viklander; Jiri Marsalek; Helene Österlund; Jon M. Hathaway; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stormwater quality; indicator bacteria; water quality assessment; VA-teknik; Urban Water Engineering; Centre - Centre for Stormwater Management DRIZZLE ; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ;

    Abstract : Stormwater and snowmelt pollution contributes to degradation of quality of the receiving waters. For assessing such impacts, it is effective to focus on specific causes of degradation, as done in this study of the quality of stormwater and snowmelt discharges into the receiving waters serving for supply of raw drinking water and water-based recreation.

  4. 22. Hydrodynamic and Microbiological Modelling of Water Quality in Drinking Water Sources

    Author : Ekaterina Sokolova; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ECO Lab; Bacteroidales; inactivation; microcosm experiment; fate and transport modelling; pathogens; microbial source tracking; MIKE 3; faecal indicators;

    Abstract : Faecal contamination of drinking water sources poses risks for waterborne disease outbreaks. To manage these risks the fate and transport of faecal contamination in a drinking water source need to be understood and quantitatively described. READ MORE

  5. 23. Evaluation of Modern Irrigation Techniques with Brackish Water

    Author : Tarek Selim Aboulila; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Soil water; Soil Salinity; Drip irrigation; HYDRUS-2D 3D; El-Salam Canal; Egypt.;

    Abstract : Modern irrigation techniques are becoming increasingly important in water-scarce countries especially in arid and semiarid regions. Higher crop production and better water use efficiency are usually achieved by drip irrigation as compared to other irrigation methods. READ MORE

  6. 24. Transport Properties and Durability of LCP and FRP materials for process equipment

    Author : Stefanie Römhild; Mikael Hedenqvist; Rodney Rychwalski; KTH; []
    Keywords : Liquid crystalline polymer LCP ; Vectra A950; disclination; annealing; transport properties; diffusion; lining; bonding; glass fibre reinforced plastics FRP ; thermoset; vinyl ester; novolac; water; water activity; sorption isotherm; long-term properties; FEP;

    Abstract : This thesis focuses on transport properties and durability of liquid crystalline polymers (LCP)and fibre reinforced plastics (FRP) with regard to application in industrial process equipment.In the first part of the study the possibility of using a thermotropic LCP of type Vectra A950as lining material for FRP process equipment was investigated.
