  2. 21. Ozonation in Advanced Wastewater Treatment : Practical Aspects and Development of a Prediction Tool for Pharmaceutical Removal

    Author : Rubén Juárez; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ozonation; wastewater; suspended solids; pharmaceuticals; bromate;

    Abstract : Pharmaceuticals that are not completely metabolized in the human body are excreted in wastewater and may find their way into surface waters, where they can have harmful effects on aquatic fauna and flora. The implementation of ozonation at wastewater treatment plants (WWTPs) can reduce the amount of pharmaceuticals discharged to the environment. READ MORE

  4. 22. Reactive filter materials for ammonium and phosphorus sorption in small scale wastewater treatment

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

    Abstract : Existing small scale wastewater treatment systems in Nordic countries have generally low treatment efficiency regarding phosphorus and nitrogen. Even though only 15% of the Swedish population is connected to on-site wastewater treatment systems, the total discharge of phosphorus from these systems exceeds the total discharge from all municipal treatment plants in Sweden.

  5. 23. Attraction channel as entrance to fishways

    Author : Elianne Wassvik; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : The utilization of rivers for hydropower production leads to problems for fish migration. Migratory fish that swim upstream for reproduction need to overcome obstructions to reach their spawning grounds. On their way upstream they follow high water velocities. READ MORE

  6. 24. Journal bearing design, lubrication and operation for enhanced performance

    Author : Gregory F Simmons; Rob Dwyer-Joyce; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : The increasing introduction of intermittent power sources combined with the de-regulation of electricity markets has led to increased instability in the electrical grid. This has led to increased start-up and shutdown of regulating power sources such as hydro-electric power plants and operation at non-ideal operating states both of which increase the wear and tear on machines.

  7. 25. Nitrifyers in constructed wetlands treating landfill leachates

    Author : Carina Sundberg; Per-Eric Lindgren; Karin Sundblad-Tonderski; Jenny Stendahl; Hans Brix; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Landfill leachate is produced many years after a landfill site closes. Hence, treatment by “natural methods”, as e.g. constructed wetlands, with low management requirements is attractive. READ MORE
