  • 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...

  • Influence of organic and ammonia loading on nitrifier activity and nitrification performance for a two-stage biological aerated filter system
    Influence of organic and ammonia loading on nitrifier activity and nitrification performance for a two-stage biological aerated filter system

    A pilot-scale, two-stage (carbon oxidation stage one, ammonia oxidation stage two) fixed film biological aerated filter (BAF) process was operated during the wintertime on-site at a domestic wastewater treatment plant. Over the study period, hydraulic loadings to the system were varied and generated a range of organic and ammonia loading conditions. Nitrification performance was monitored based on water quality along the length of the filters, effluent water quality, and activity levels of ammonia...

  • Monitoring and control of a partially packed biological aerated filter (BAF) reactor for improving nitrogen removal efficiency
    Monitoring and control of a partially packed biological aerated filter (BAF) reactor for improving nitrogen removal efficiency

    This paper examines on-off systems and automatic monitoring and control of a biological aerated filter to identify the end point of nitrification and denitrification processes, and chemical oxygen demand (COD), ammonia-nitrogen removal (NH 3 -N) and aeration savings. Oxidation-reduction potential (ORP), pH and dissolved oxygen (DO) were measured on-line and chemical parameters were measured in the wastewater. The ‘nitrate knee’ in the ORP profile was characterised by a breakpoint at average 160 min...

  • Comparison of combined and separated biological aerated filter (BAF) performance for pre-denitrification/ nitrification of municipal wastewater
    Comparison of combined and separated biological aerated filter (BAF) performance for pre-denitrification/ nitrification of municipal wastewater

    The performance of two systems of semi-industrial up-flow biological aerated filters (BAF) with pre-denitrification followed by nitrification was studied and compared under various operating and loading conditions. The first system consisted of two separate reactors for the denitrification and the nitrification step, whereas in the second system the aerobic nitrification zone was packed on top of the anoxic denitrification zone in one reactor. The second system potentially offers substantial savings...
