“…Also, the PN/PS increased with extension of time. This result was consistent with the previous research (Zhu et al, 2012), but had obvious differences with the study of Luo et al (2014). The reason for this comparative analysis might focus on the inoculated sludge source, wastewater characteristics, and sludge granulation.…”

“…S2 shows the 3D-EEM results of EPS in both reactors on day 30. Both 3D-EEM spectra provides information about two major substances of EPS: aromatic protein (peak A, Ex/Em = 200–250/280–380) and tryptophan protein like (peak B, Ex/Em = 250–310/320–380) [40]. The locations of peaks have not changed in R2, indicating no distinct changes of the structure and functional groups of EPS.…”

A novel biological nitrogen removal system based on nitritation coupled with thiosulfate-driven denitritation (Nitritation-TDD) was developed to achieve a high nitrogen removal rate and low sludge production. A nitritation sequential batch reactor (nitritation SBR) and an anoxic up-flow sludge bed (AnUSB) reactor were applied for effective nitritation and denitritation, respectively. Above 75% nitrite was accumulated in the nitritation SBR with an influent ammonia loading rate of 0.43 kg N/d/m3. During Nitritation-TDD operation, particle sizes (d50) of the sludge decreased from 406 to 225 um in nitritation SBR and from 327–183 um in AnUSB reactor. Pyrosequencing tests revealed that ammonium-oxidizing bacteria (AOB) population was stabilized at approximately 7.0% (calculated as population of AOB-related genus divided by the total microbial population) in the nitritation SBR. In contrast, nitrite-oxidizing bacteria (NOB) population decreased from 6.5–0.6% over the same time, indicating the effective nitrite accumulation in the nitritation SBR. Thiobacillus, accounting for 34.2% in the AnUSB reactor, was mainly responsible for nitrogen removal via autotrophic denitritation, using an external source of thiosulfate as electron donor. Also, it was found that free nitrous acid could directly affect the denitritation activity.
