The development of simultaneous partial nitrification, ANAMMOX and denitrification (SNAD) process in a single reactor for nitrogen removal.
The simultaneous partial nitrification, ANAMMOX and denitrification (SNAD) process was validated to potentially remove ammonium and COD from wastewater in a single, oxygen-limited, non-woven rotating biological contactor (NRBC) reactor. An ammonium conversion efficiency of 79%, TN removal efficiency of 70% and COD removal efficiency of 94% were obtained with the nitrogen and COD loading rate of...
متن کاملEffect of Dissolved Oxygen and Chemical Oxygen Demand to Nitrogen Ratios on the Partial Nitrification/Denitrification Process in Moving bed Biofilm Reactors
Partial nitrification was reported to be technically feasible and economically favorable, especially for wastewaterwith high ammonium concentration or low C/N ratio. In this study, the effect of dissolved oxygen (DO)and influent ratio of chemical oxygen demand to nitrogen (COD/N) ratio on biological nitrogen removal fromsynthetic wastewater was investigated. Experiments were c...
متن کاملClosed water recirculating system for fish rearing equipped with bioreactor capable of simultaneous nitrification and denitrification.
Five crucian carp, Carassius auratus langsdorfiicarps had been reared in a closed water recirculating system. The system was equipped with the compact bioreactor using the plate gels capable of both nitrification and denitrification in a single unit. Ammonia and nitrite concentrations in the rearing water had been maintained below 0.05 mg-N/L, and nitrate concentration also controlled between 2...
متن کاملNitrogen Removal from Milking Center Wastewater via Simultaneous Nitrification and Denitrification using a Biofilm Filtration System
Milking center wastewater (MCW) has a relatively low ratio of carbon to nitrogen (C/N ratio), which shall be separately managed from livestock manure due to the negative impacts of manure nutrients and harmful effects on down-stream of livestock manure process with respect to the microbial growth. Simultaneous nitrification and denitrification (SND) is corresponded by the inhibition of second n...
متن کاملDevelopment of simultaneous partial nitrification, anammox and denitrification (SNAD) process in a sequential batch reactor.
Simultaneous partial nitrification, anammox and denitrification (SNAD) process was developed in a sequential batch reactor (SBR) and the influence of hydraulic retention time (HRT) on the SNAD process was investigated. Around 96% NH(4)(+)-N removal and 87% COD removal were observed at 9 d HRT. Marginal decreases in the removal efficiencies were observed when the HRT was reduced to 3d or the loa...
