  1. 1. Treatment of organic pollutants in high salinity wastewater : new catalysis systems

    Författare :Han Yu; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High salinity wastewater; Electrochemical catalysis; Photo-electro catalysis; Degradation;

    Sammanfattning : High salinity wastewater (HSW, NaCl mass fraction ≥ 1%) from industries and aquacultures contains massive organic matters with a wide variety. These organic matters have been considered as significant threaten to both human and environment. The removal and degradation of them before discharge emerge as necessity. LÄS MER

  2. 2. Anammox-based systems for nitrogen removal from mainstream municipal wastewater

    Författare :Andriy Malovanyy; Elzbieta Plaza; Adriano Joss; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wastewater; Nitrogen removal; Ion exchange; Deammonification; Anammox; Mainstream; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : Nitrogen removal from municipal wastewater with the application of deammonification process offers an operational cost reduction, especially if it is combined with a maximal use of organic content of wastewater for biogas production. In this thesis, two approaches for integration of the deammonification process into the municipal wastewater treatment scheme were studied. LÄS MER

  3. 3. Ammonium removal from municipal wastewater with application of ion exchange and partial nitritation/Anammox process

    Författare :Andriy Malovanyy; Elzbieta Plaza; Andrei Zagorodni; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wastewater; nitrogen removal; ion exchange; nitritation; Anammox;

    Sammanfattning : Nitrogen removal from municipal wastewater with application of Anammox process offers cost reduction, especially if it is combined with maximal use of organic content of wastewater for biogas production. In this study a new technology is proposed, which is based on ammonium concentration from municipal wastewater by ion exchange followed by biological removal of ammonium from the concentrated stream by partial nitritation/Anammox process.

  4. 4. Groundwater-Seawater Interactions : Seawater Intrusion, Submarine Groundwater Discharge and Temporal Variability and Randomness Effects

    Författare :Carmen Prieto; Georgia Destouni; Vassilios Kaleris; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydraulic engineering; Seawater intrusion; submarine groundwater discharge; coastal groundwater management; coastal zone management; temporal variability; temporal randomness; Vattenteknik; Water engineering; Vattenteknik;

    Sammanfattning : Fresh groundwater quality and availability in coastal areas is affected by seawater intrusion into coastal aquifers, and coastal water quality and ecosystem status may be significantly affected by groundwater pollutants that are transported into coastal waters by submarine groundwater dis-charge (SGD). This thesis uses an overall regional perspective for investigating: i) seawater intru-sion and its possible control in sustainable coastal groundwater management; ii) SGD and its relevant quantification as one interacting part among the diverse main regional pathways of freshwater and tracer/pollutant inputs from land to sea; and iii) the integrated system functioning of both i) and ii) as main components of the same coastal groundwater system.
