“…Nitrite is critical for nitrogen removal because a significant amount of nitrite is the premise for the subsequent denitrification, so the stability of nitrite accumulation was investigated in a sequencing batch reactor [16]. In addition, it has been reported that some factors such as pH [17], carbon source [15], and temperature [34] affected nitrite accumulation in the treatment of piggery wastewater, which seems to be contradictory to the results in the current study. However, considering that P. putida could reduce nitrite rapidly (Fig.…”

This work evaluates the efficiency of ammonium removal from piggery wastewater using a sequencing batch reactor (SBR) inoculated with a newly isolated strain of Pseudomonas putida HJH1. The strain HJH1 not only could survive and remove up to 72.4 mg/L NO 2 --N under aerobic conditions, but it also has good performance for simultaneous nitrification and denitrification (SND) with no nitrite accumulation. The SBR system was able to consistently remove: 1) 76.4-100% ammonium nitrogen and 71.4-100% COD from artificial wastewater in stage 1, and 2) 89.2-99.1% ammonium nitrogen and 82.4-100% COD from piggery wastewater in stage 2. During the whole operation, the strain HJH1 predominated in the SBR all the time to function together with other bacteria. Results indicated that the SBR system inoculated with Pseudomonas putida HJH1 can efficiently remove ammonium nitrogen from piggery wastewater, thereby having potential applications for future nitrogen removal.

“…However, in a pre-nitrifying process, nitrate as the end product of nitrification could accumulate in the aerobic compartment and slowly move into the anoxic compartment through mass transfer. Obaja et al (2003) observed that nitrate increased constantly when all ammonium was nitrified to nitrate in their nitrification and denitrification study using a sequencing batch reactor. However, ammonia and nitrate removal efficiency reached 99.7 and 99.9%, respectively.…”

Water body deterioration caused by natural and anthropogenic activities has been a source of concern for regulating agencies. Several problems such as eutrophication and blue baby syndrome are caused by the excessive presence of nutrients within the aquatic biota. This also presents danger to the benthic community. In this study, an integrated aerobic/anoxic attached growth bioreactor was evaluated for its performance in removing nutrients (ammonia and nitrate) from simulated synthetic low and medium strength domestic wastewater. The experiment was conducted in two stages. ) was low in both stages 1 and 2. In both stages 1 and 2, ammonia removal reached 98%. The HRT was found to exert slight influence in nutrient removal using the integrated bioreactor. At HRT of 7.2 and 12 days, effluent ammonia concentration of 1.1 and 0.6 mg LG 1 was obtained, whereas effluent nitrate was in the range of 0.55 and 0.22 mg LG 1 , respectively. Chemical Oxygen Demand (COD) was also monitored at steady states and was found below 20 mg LG 1 in both stages 1 and 2 at HRT of 12 days. This study, therefore demonstrates the capacity of an integrated bioreactor to mitigate the enormous challenge of water body deterioration and toxicity caused by indiscriminate discharge of polluted wastewater.

Abstract. The objective of this study was to investigate the pollutant removal efficiency of different types of wastewaters by a sequencing batch reactor (SBR). A laboratory-scale SBR was used to treat sewage, medical wastewater and industrial wastewater. The effects of different conditions of aeration, stirring and settling on the efficiency of pollutants removal were explored to optimize the performance, especially for the removal of organic matter (COD), ammonia nitrogen (NH 4 + -N), total nitrogen(TN) and total phosphorus(TP) of different types of polluted water. From the results it was showed that when aeration 6 hours, stirring 4 hours and settling 2 hours in SBR, the removal rates of COD, nitrogen and phosphorus of domestic sewage were 93%, 98% and 83%, respectively; when aeration 5 hours, stirring 5 hours and settling 1 hour in the SBR, the removal rates of COD and nitrogen of pharmaceutical wastewater were 83% and 90%, respectively; when aeration 4 hours, stirring 4 hours and settling 1 hour in the SBR, removal rates of COD, nitrogen and phosphorus of industrial wastewater were 97%, 93% and 97%, respectively.
