  1. 16. Numerical simulations of mixing for gas exhaust treatment

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Viktor Lahti; [2019]
    Keywords : ;

    Abstract : According to the World Health Organisation, nine out of ten people live in places with sub par air quality. Therefore, the study of the treatment of polluted air is from a global point of view of great importance, and a matter of life quality for both humans and as well as animals. READ MORE

  3. 17. Possibilities for removal of micropollutants in small-scale wastewater treatment - methods and multi-criteria analysis

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Anqi Li; [2018]
    Keywords : pharmaceuticals; column experiment; removal efficiency; absorbents;

    Abstract : The quality of worlds’ water resources is facing new challenges, for instance detectable concentration of various trace contaminants under the term micropollutants is discharging into water bodies from both municipal wastewater treatment plants and from on-site wastewater facilities. A project called RedMic aim at identifying and quantifying emissions of micropollutants from on-site wastewater treatments as a basis for providing innovative treatment technologies to reduce potential risks for groundwater and surface water contamination.

  4. 18. Ozonation of pharmaceutical residues in a wastewater treatment plant : Modeling the ozone demand based on a multivariate analysis of influential parameters

    University essay from Linköpings universitet/Teknisk biologi

    Author : Erica Engberg; Emilia Johansson; [2018]
    Keywords : ;

    Abstract : Most pharmaceutical residues in wastewater treatment plants (WWTPs) end up in the hydrosphere where they cause negative effects on the aquatic life and might disrupt ecosystems. By implementing an ozonation step (treatment with ozone) in the wastewater treatment process, these pharmaceutical residues can be reduced. READ MORE

  5. 19. Ozone Treatment Targeting Pharmaceutical Residues : Validation and Process Control in a Wastewater Treatment Plant

    University essay from Linköpings universitet/Teknisk biologi

    Author : Erik Fornander; [2018]
    Keywords : Ozone; Ozone treatment; Wastewater; Process control; Pharmaceutical residues; Wastewater treatment plant; Validation; Modelling;

    Abstract : Major studies conducted in Europe and North America has concluded that the current processes in wastewater treatment plants insufficiently degrade micropollutants e.g. pharmaceutical residues. Several sorption and oxidation methods has therefore been investigated with the purpose of removing or degrading micropollutants in wastewater. READ MORE

  6. 20. A review on ozonation and17a-ethinylestradiol - formation and effects in the environment of the by-products

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Erica Svensson; [2017]
    Keywords : Ethinylestradiol; EE2; By-products; Ozonation products; Transformation products; Ozonation; Earth and Environmental Sciences;

    Abstract : Today, waste water treatment plants do not remove pharmaceutical residues from the water (as there are currently no regulations for wastewater treatment in regards to pharmaceuticals residues in Sweden) resulting in a high concentration of pharmaceuticals reaching the environment. The Swedish environmental protection agency have recently concluded that there is a need for advanced treatment of pharmaceuticals in wastewater. READ MORE
