    Sammanfattning : After the sewage wastewater is collected from different households and directed to the treatment plants, it goes through several processes, which are physical, chemical and biological. The different processes remove the contaminant, and produce a semi-solid material named sludge. Sludge has a huge amount of liquid. LÄS MER

  3. 3. Adsorption of micropollutants in wastewater using pulverized activate carbon - The influence of organic matter content and characteristics

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Anna Nicola Messinger; [2019]
    Nyckelord :Pulverised Activated carbon; PAC; UVA254; Wastewater treatment; Micropollutants; Activated carbon; Earth and Environmental Sciences;

    Sammanfattning : Wastewater is one of the biggest emission sources of organic micropollutants to the aquatic environment. Due to the negative effects of micropollutants on the receiving waters, advanced treatment steps are needed to reduce these emissions. Activated carbon is one promising approach. LÄS MER

  4. 4. Produktion av näringspellets med varierad mekanisk kraft och ligninhalt : Utvärdering av pelletsegenskaper och energianvändning

    M1-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

  5. 5. Processes and drivers of biological and chemical Phosphorus removal in wastewater treatment plants

    Magister-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Författare :Javad Kordi; [2019]
    Nyckelord :;

    Sammanfattning : Phosphorus (P) is one of the most important elements exists in wastewater in soluble forms. Several methods have been using for P recovery in wastewater treatment plants, but this study tried to investigate on the most important drivers and the processes of biological phosphorus removal (EBPR) and chemical phosphorus removal that are the major technics of P recovery globally.
