  2. 1. Innovative treatment technologies for PFAS-contaminated water - Utilizing foam partitioning and exploring electrochemical oxidation

    Author : Sanne Smith; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The presence of per- and polyfluoroalkyl substances (PFAS) in the aquatic environment has become a global cause for concern. PFAS are persistent anthropogenic chemicals, and certain PFAS are known to be mobile, bioaccumulative and toxic. READ MORE

  4. 2. Climatic conditions inside nuclear reactor containments - Monitoring campaign

    Author : Mikael Oxfall; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nuclear power plant; concrete; onsite measurements; relative humidity; boiling water reactor; pressurized water reactor; moisture transport coefficient; moisture flux.;

    Abstract : The reactor containment is one of the most important buildings at a nuclear power plant. In case of an accident the containment wall is the final protection against radioactive leakage to the surrounding environment. A reactor containment contains different types of concrete structures.

    Abstract : The United Nations (UN) has adopted 17 “Sustainable Development Goals” (SDGs) to achieve a clean, better and sustainable future. SDG 6 is to ensure that everyone has access to clean water and sanitation by 2030. READ MORE

  6. 4. Controlling and monitoring of deammonification process in moving bed biofilm reactor

    Author : Jingjing Yang; Elzbieta Plaza; Britt-Marie Wilén; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : It is considered that partial nitrification combined with anammox, named deammonification, is more environmental friendly compared with conventional nitrification/denitrification due to decrease energy requirement, low emission of CO2 and N2O. Dissolved oxygen (DO) is a significant parameter influencing the nitrogen removal rate and activity of different microorganisms. READ MORE

  7. 5. Start-up and operational strategies for deammonification plants : - a study with one-stage moving bed biofilm reactors treating reject water

    Author : Linda Kanders; Eva Thorin; Susanne Lackner; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : To limit eutrophication, wastewater treatment plants use biological methods to convert degraded nitrogen to nitrogen gas. Deammonification, or partial nitritation in combination with anammox, has been shown to be an energy efficient process. READ MORE
