  2. 21. 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

  4. 22. Metal pathways in stormwater treatment systems

    Author : Laila Søberg; Lian Lundy; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Abstract : Heavy metals in urban stormwater runoff affect the ecological status of receiving surface waters. To avoid this, various stormwater treatment systems have been developed and implemented during the last 50 years. One of themost common and continuously popular systems is wet stormwater ponds.

  5. 23. Floating treatment wetlands for stormwater management : Plant species selection and influence of external factors for heavy metal and chloride removal in a cold climate

    Author : Maria Schück; Maria Greger; Hans Brix; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Floating treatment wetlands; Phytodesalination; Rhizofiltration; Phytoremediation; Stormwater; Heavy metals; Chloride; Plant traits; Carex riparia; Carex pseudocyperus; Phalaris arundinacea; Flytande våtmarker; dagvatten; tungmetaller; klorid; fytoremediering; slokstarr; rörflen; jättestarr; växtfysiologi; Plant Physiology;

    Abstract : Stormwater, which consists of rainwater and snowmelt, often contains pollutants from vehicle traffic, building materials, and industries. These pollutants include chloride and heavy metals, which can cause several environmental issues, such as being toxic to biota at elevated concentrations. READ MORE

  6. 24. Microalgae at wastewater treatment in cold climate

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

    Abstract : The thesis concludes that microalgae may improve wastewater treatment in ponds in cold climate, from a treatment perspective as well as a sustainability perspective. A literature review revealed that the microalgae biomass produced may find economic use, depending on what species will come to dominate, since there are many possible products from microalgae biomass.

  7. 25. Metal and microplastic treatment in stormwater bioretention

    Author : Katharina Lange; Helene Österlund; Elodie Passeport; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ; Centre - Centre for Stormwater Management DRIZZLE ;

    Abstract : Metals and microplastic particles are common stormwater pollutants, which can be harmful when released to the environment. The aim of this thesis is to increase the understanding of the treatment of metals and their different fractions, as well as microplastic, in bioretention systems. READ MORE
