  1. 1. Constructed wetland for post-treatment of phosphorus in wastewater : An initial assessment of potential design and application to a small-scale water treatment plant in Åre municipality, Sweden

    University essay from Mittuniversitetet/Institutionen för naturvetenskap, design och hållbar utveckling (2023-)

    Author : Johan Arnemo; [2023]
    Keywords : : cold climate; ecological engineering; free water surface wetland; horizontal subsurface wetland; phosphorus treatment;

    Abstract : In recent years, the treatment of phosphorus in Nyland's water treatment plant (located in Åre municipality) has been substandard. The problem has persisted despite attempts to lower the concentration to meet the emission requirements. READ MORE

  2. 2. Energy improvement options for a small-scale brewery: a literature study

    University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

    Author : Eneko Arana; [2022]
    Keywords : Brewing industry; energy audit; energy efficiency; environmental impact; sustainability and energy recovery.;

    Abstract : In the age of technology and development in which we live nowadays, it is inevitable to realise that this so-called progress is translated into pollution, damage to the environment and abuse of energy and fossil fuels. The companies and factories that produce the goods we need, use a lot of energy and pollute in massive ways, posing dilemmas such as how to make these companies more energetically and environmentally efficient, with the aim of decreasing the emissions and energy use.

  3. 3. Removal of per- and polyfluoroalkyl substances(PFAS) from contaminated leachate usingaeration foam fractionation

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Axel Krögerström; [2021]
    Keywords : PFAS; Foam Fractionation; Leachate; Removal Efficiency; Wastewater Treatment;

    Abstract : Leachate from landfills is contaminated in many ways and per- and polyfluoroalkyl substances (PFAS)-contamination is one of them. Recent studies have demonstrated the environmental and human concerns of PFAS. Therefore, the treatment of leachate is important. READ MORE

  4. 4. Investigating the state of rural water supply in Rio Grande do Sul, Brazil - a regional study on the implementation of United Nations Sustainable Development Goal 6.1: safe and affordable drinking water for all

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Keywords : Drinking water; Sustainable development goal 6; Rural water supply; Water safety; Rio Grande do Sul; Technology and Engineering;

    Abstract : Access to clean drinking water is a human right and a necessity for life, yet many rely on precarious water sources across the world. The United Nations outlines a great aspiration in Agenda 2030 - that safe and affordable drinking water should be available for all by 2030. READ MORE

  5. 5. 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
