Micropollutant Removal in Low NH4⁺-N Bioreactors
is possible under biological treatment conditions with low
NH4+—N concentrations and high C:N ratios, two 12-L
sequencing batch reactors were run in series down-stream of a full-scale
municipal activated sludge process. The full-scale plant contained three
equally sized compartments (one anoxic and two oxic, 2 mg/L
O2) and was operated with 1 d HRT, ∼25 d SRT, ∼2 g/L SS. The
two 12-L post-treatment reactors were operated in series with carriers (K1,
AnoxKaldnes; 40% fill ratio), a HRT of 24 h per reactor and three batches per
day. In the first post-treatment reactor, the batch cycle contained two
reaction phases: one oxic (5–6 h) with 0.5–2.5 mg/L O2, and
one anoxic (1–2 h) with acetate addition (40 mg/L DOC). In the second
post-treatment reactor, the batch cycle contained one oxic reaction phase
(7–8 h) with 0.2–1.5 mg/L O2 and acetate addition (110 mg/L
DOC).
A 3-week sampling campaign was conducted six months after
reactor start-up. Daily flow proportional samples of the influent and effluent
from each reactor were collected, filtered (MN GF-5, 0.4 μm, Macherey-Nagel)
and stored at 6 °C until the end of each sampling week. The samples were then
mixed proportionally to the flow to obtain 7-day composite samples and stored
at −20 °C until analysis.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
