  1. 1. Biofilms in Nitrogen Removal - Bacterial Population Dynamics and Spatial Distribution

    Författare :Robert Almstrand; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; AOB; NOB; biofilms; image analysis; FISH; Nitrosomonas; population dynamics; spatial distribution;

    Sammanfattning : Efficient nitrogen removal at wastewater treatment plants (WWTPs) is necessary to avoid eutrophication of recipient waters. The most commonly used approach consists of aerobic nitrification and subsequent anaerobic denitrification resulting in the release of dinitrogen gas into the atmosphere. LÄS MER

  3. 2. Bioassays for the determination of nitrification inhibition

    Författare :Camilla Grunditz; KTH; []
    Nyckelord :;

    Sammanfattning : Requirements for nitrogen reduction in wastewater treatmentplants were introduced in Sweden in the early 1990’s. Thiswas a governmental move to reduce the nitrogen discharges tothe Baltic and Kattegatt in order to prevent eutrophication.The nitrification process in wastewater treatment plants isperformed by nitrifying bacteria.

  4. 3. Nitrifyers in constructed wetlands treating landfill leachates

    Författare :Carina Sundberg; Per-Eric Lindgren; Karin Sundblad-Tonderski; Jenny Stendahl; Hans Brix; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Landfill leachate is produced many years after a landfill site closes. Hence, treatment by “natural methods”, as e.g. constructed wetlands, with low management requirements is attractive. LÄS MER

  5. 4. Dynamic Modeling of Nitrifying Trickling Filters

    Författare :Torsten Wik; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Distributed parameter system; Trickling Filter; Biofilm; Process Model; Experiments; Wastewater; Dynamics;

    Sammanfattning : Trickling filters, one kind of biofilm reactors, for removal of nitrogen in municipal wastewater are presently increasing in number in Sweden. For improved control and operation of wastewater treatment plants, where such reactors are used, dynamic models describing their behavior are necessary. LÄS MER
