    Abstract : 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. READ MORE

  4. 3. Biogas Production : Anaerobic Digestion of Grains Diluted in Process Water from a Wastewater Treatment Plant

    University essay from Institutionen för tematisk utbildning och forskning

    Author : Anna Lundén; [2003]
    Keywords : Interdisciplinary studies; Anaerobic digestion; sewage sludge; biogas; Tekniska verken; TVÄRVETENSKAP;

    Abstract : In light of constant research regarding the development of alternate fuels, anaerobic digestion of grains diluted in process water from a wastewater treatment plant has been investigaed by starting biogas reactors to produce methane. The possibility of using the sludge from the reactors as fertilizer was also explored. READ MORE
