  1. 1. Effect of biofilm thickness and carrier type on the performance of anaerobic moving bed biofilm reactors (AnMBBRs)

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Astrid Hermansson; [2020]
    Keywords : Anaerobic; wastewater treatment; AnMBBR; MBBR; biofilm thickness; carrier; organic removal; water engineering; environmental engineering; avloppsteknik; vattenförsörjningsteknik; Technology and Engineering;

    Abstract : The anaerobic moving bed biofilm reactor (AnMBBR) is a wastewater treatment process that has shown effective for the treatment of industrial wastewaters. As the AnMBBR is a biofilm process, nutrients, products, etc. must be transported through the biofilm. The thickness of the biofilm may, therefore, impact the process. READ MORE

  3. 2. The possibilities of recycling wash water at Vidinge

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Julia Mauritzson; [2020]
    Keywords : reuse; treatment; fresh-cut; water engineering; environmental engineering; avloppsteknik; vattenförsörjningsteknik; Technology and Engineering;

    Abstract : Water is a resource of importance and with drier weather around the world, including Swe-den, there is a risk of too low levels of water to satisfy for instance households, animals and industries in the future. Fresh-cut fruit and vegetable industries are water intense and almost all process water is used in the washing process. READ MORE

  4. 3. Yield of Bromate from Ozonated Wastewater and the Potential for Biological Reduction of Bromate in Wastewater in Sweden

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Lauren Dell; [2020]
    Keywords : biological reduction; bromate; ozonation; disinfection by-products; bromide; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Technology and Engineering;

    Abstract : The impact that anthropogenic micropollutants have on the environment is increasingly gaining attention. As a result of this, Sweden, among other countries, is looking towards implementing advanced treatment for micropollutant and pharmaceutical product removal from wastewater prior to discharge into the environment.

  5. 4. Pulse Electric Field as a Pre-treatment Method of Wastewater Sludge prior to Anaerobic Digestion

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Milton Matilde; [2020]
    Keywords : PEF; AD; biogas yield; sludge pre-treatment; water engineering; environmental engineering; avloppsteknik; vattenförsörjningsteknik; Technology and Engineering;

    Abstract : This work analyzed the impact caused by different intensities of Pulsed Electric Fields (PEF) pre-treatment on the biogas production from small-scale anaerobic digesters of wastewater sludge under thermophilic conditions. PEF technology consists of passing the substrate through an electric field which generates a potential difference across the cells, resulting in electroporation. READ MORE

  6. 5. Partial denitrification as nitrite provider for mainstream anammox

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Felix Wallin Holmin; [2020]
    Keywords : Water engineering; Environmental engineering; Mainstream anammox; Partial denitrification; PDA; MBBR; Nitrogen removal; Vattenförsörjningsteknik; Avloppsteknik; Technology and Engineering;

    Abstract : In traditional wastewater treatment, nitrogen is removed through the biological process combination of nitrification and denitrification. Although it is a well-established method, the need for aeration and possible addition of an external carbon source results in it being an energy-negative and costly process, thus making alternative methods for nitrogen removal compelling to examine.
