Page: 1. Upstream denitrification
Waste water, return sludge and internal recirculation are mixed in the denitrification basin. Both denitrification and nitrification rebwp8:2 Nitrification basins can be configured as cascades. To increase operating flexibility, it can be possible for the last parts of the denitrification basin (in the direction of flow ...

Page: 2. Cascade denitrification
Waste water flows through two or more activation basins (each with an upstream or simultaneous denitr. stage) conse­cutively, with the waste water being fed in a divided manner to the denitr. basin (à internal recirculation omitted). High O ...

Page: 3. Simultaneous denitrification
type of upstream denitrification with a high internal return ratio can be realised in the circulation basin with nitr. and denitr. zones. 8090 % N can be removed like this. \\ \\ !UBT477Simultane Deni.jpg border=1

Page: 3 Denitrification
Aerobic rebwp8:Oxygen content nitrification rebwp8:2 Nitrification is followed by denitrification in an anoxic rebwp8:Oxygen content basin (no dissolved O{}2, nitrate acts as the O{}2 source). Here, NO{}3{}\ is reduced by heterotrophic Cdegrading bacteria ...

Page: 4. Alternating denitrification
Two basins which are aerated intermittently in each case are loaded alternately one after the other, with water from the loaded, nonaerated basin flowing into the other, aerated basin and from there to the final sedimentation stage. \\ \\ !UBT478Alternierende Deni.jpg border=1

Page: 5. Intermittent denitrification
nitrification rebwp8:2 Nitrification and denitrification phases alternate over time in a single basin. \\ \\ !UBT479Intermittierende Deni.jpg border=1

Page: 6. Downstream denitrification
used when the waste water has a very low C/N ratio so that the addition of external carbon is unavoidable. For the sake of safety it is followed by a subsequent aeration basin. \\ \\ !UBT480Nachgeschaltete Deni.jpg border=1

Page: Activation basin-trickling bed combination
case the BOD5 rebwp8:BOD5 removal takes place in the first stage (activat­ion basin) and the nitri­fication rebwp8:2 Nitrification takes place in the second stage (trick­ling bed rebwp8:Trickling bed method ). A final sedi ...

Page: N removal
Nitrogen is present in waste water partly as organic N, partly as NH{}4\N. Organic N can be used either directly for building up bacterial mass or is converted by bacterial enzymes into NH{}4\N (hydrolysis). In a first step ...

Page: pH value
Activation methods rebwp8:Activated sludge method are less sensitive to pH variations than trickling bed rebwp8:Trickling bed method methods owing to the greater volumes. The pH in the activation basin should generally be between 6.5 and 8.5 (the growth ...
