| dc.description.abstract | It is a known fact that access to drinking water is becoming more difficult all over the world. Excessive consumption of water causes increased salinity in existing resources. Therefore, it is necessary to develop economical and efficient treatment methods for both nitrogen removal and against salting in order to access safe drinking water. The present study analyses the effect of salinity on the process performance of sulfur-based autotrophic denitrification/denitritation, which is a low-cost and efficient method for drinking water purification. The bioreactor was operated under different salt concentrations (0.05–4 % or 0.5–40 g NaCl/L), nitrate/nitrite loading rates (NLR) (0.033–0.62 gNO3-N/(L.d)), and hydraulic retention times (HRTs) (18–8 h). Even at a high salt concentration such as 4 % NaCl, which is not very common in drinking water, denitrification (nitrate removal efficiency (NRE) 99.36 %) was found to occur smoothly. NRE decreased by up to 33 % at low HRT values (8 h). Compared to denitrification, denitritation performance was higher and no negative effect of salt concentration was observed. Sulfur-based autotrophic denitrification/denitritation process was found to be highly effective in nitrate and nitrite removal from salt water. | |
