“…This was not in line with the findings from Liu et al [17]. Both NH 4 + -N/ SO 4 2--S conversion ratio (at 15.96 ± 2.41) and n(TN)/n(TS) removal ratio (at 9.69±1.84) were far away from the theoretical value [10,17] when n(N)/n(S) was 4. At the same time, 38.7% of the converted NH 4 + -N was oxidized to NO 3 --N. Therefore, it is concluded that n(N)/n(S) had little effect on NH 4 + -N conversion efficiency.…”

“…According to autotrophic denitrification experiments, the reduction product of SO 4 2--S is S 0 instead of S 2-. HS -/S 2-also were not detected in the experiment of Liu et al [17], which was implemented in an inorganic environment too. Liu et al [17] speculated the reactions of sulfate reduction-ammonia oxidation in Equations (5) and (6) …”

“…For instance, some researchers considered that S 2-should be the intermediate product [10,[18][19] due to S 2-detection in heterotrophic environment. While other researchers considered S 2-should not be the intermediate product [17] due to no S 2-observed in autotrophic environment. pH value increased in autotrophic environment [17] but decreased in heterotrophic environment [19,20].…”

ABSTRACT:The sulfate reduction-ammonia oxidation reaction with ANAMMOX sludge at autotrophic condition was investigated. It was found that the pH level decreased, and elemental sulfur and dinitrogen were produced at the end of this process, while NO 3 --N was a byproduct. A lower ratio of n(N) to n(S) can improve SO 4 2--S conversion ratio where a larger portion of NH 4 + -N was oxidized into NO 3 --N, resulting in a decreased removal ratio of n(TN)/n(TS). This indicates that ammonia can be oxidized into NO 2 --N or NO 3 --N by sulfate, then the residual NH 4 + -N and the produced NO 2 --N would be removed via ANAMMOX.

This paper examines correlations and processes related to nutrient removal in a wastewater treatment plant (WWTP), verifying the efficiency of plant improvements and the extent that public awareness campaigns have had on treated water quality. Increases in water pH value resulted in a decrease in nitrate nitrogen and phosphate phosphorus levels in treated wastewater, demonstrating a better performance of microorganisms with higher pH values. On the contrary, both nutrients proved to increase with increasing temperatures, although there were no significant differences in the nitrogen loading rate, representing a good behavior of the WWTP despite the considered season. This fact can be explained by a new storm tank located at the sewage plant that cushions sharp-point organic loads, allowing a more stable performance of the WWTP. An increase in electrical conductivity resulted in higher phosphate phosphorus levels in the effluent, indicating a special sensitivity of phosphorus accumulating organisms (PAOs) to high osmotic pressures. High C/N ratios, both chemical oxygen demand and biochemical oxygen demand resulted in lower nitrification rates, indicating the favored growth of heterotrophs over slow-growing nitrifying bacteria. Sludge age proved to have a strong effect on nutrients removal, increasing the diversity of ammonia oxidizing bacteria but worsening the nitrogen removal efficiency with older solids residence time. In order to meet the requirements of the Council Directive (91/271/CEE) for phosphate phosphorus removal, an anaerobic selector for PAOs growing should be implemented.
