  • Distribution of heterotrophic and autotrophic organisms in a biological aerated filter
    Distribution of heterotrophic and autotrophic organisms in a biological aerated filter

    Biological aerated filtration is a viable option for small municipal wastewater treatment plants. A low cost filter media was obtained by triturating volcanic rock. An apparent porosity of 46 % and a specific surface area of 395 m 2 /m 3 ·d were obtained once the filter was packed by using a grain size of 8.2 mm. The performance of the system, operated as a biological filter, was evaluated under an average organic load of 2.6±0.4 kgCODT/m 3 ·d (6.7±1.1 gCODT/m 2 ·d) without primary and secondary...

  • Biological active groundwater filters: exploiting natural diversity
    Biological active groundwater filters: exploiting natural diversity

    In the Netherlands, biological trickling filters without chemical pre-oxidation are generally applied to treat anaerobic groundwater, containing methane, iron, ammonium and manganese. Previous research showed that all compounds can be removed in one filter step and that not only the ammonia oxidation (by nitrification), but also the iron oxidation is often a biological process, despite oxygen saturated conditions and neutral pH. However, the optimal conditions for each process differs. In this paper...

  • Nitrogen-removal efficiency in an upflow partially packed biological aerated filter (BAF) without backwashing process
    Nitrogen-removal efficiency in an upflow partially packed biological aerated filter (BAF) without backwashing process

    An upflow, partially packed biological aerated filter (BAF) reactor was used to remove nitrogen in the form of ammonia ions by a nitrification process that involves physical, chemical and biological phenomena governed by a variety of parameters such as dissolved oxygen concentration, pH and alkalinity. Dissolved oxygen (DO) and pH were shown to have effects on the nitrification process in this study. Three C:N ratios i.e., 10, 4 and 1 were compared during this study by varying the nitrogen loading...
