Nitrogen Removal from Milking Center Wastewater via Simultaneous Nitrification and Denitrification Using a Biofilm Filtration Reactor
Milking center wastewater (MCW) has a relatively low ratio of carbon to nitrogen (C/N ratio), which should be separately managed from livestock manure due to the negative impacts of manure nutrients and harmful effects on down-stream in the livestock manure process with respect to the microbial growth. Simultaneous nitrification and denitrification (SND) is linked to inhibition of the second ni...
متن کاملSimultaneous nitrification/denitrification and trace organic contaminant (TrOC) removal by an anoxic-aerobic membrane bioreactor (MBR).
Simultaneous nitrification/denitrification and trace organic contaminant (TrOC) removal during wastewater treatment by an integrated anoxic-aerobic MBR was examined. A set of 30 compounds was selected to represent TrOCs that occur ubiquitously in domestic wastewater. The system achieved over 95% total organic carbon (TOC) and over 80% total nitrogen (TN) removal. In addition, 21 of the 30 TrOCs...
متن کاملTotal Nitrogen Removal in a Completely Mixed Membrane Biofilm Reactor for Nitrification and Denitrification
A Hollow-fiber Membrane Biofilm Reactor (MBfR) was used to nitrify and denitrify synthetic wastewater to remove nitrogenous pollutants such as ammonium, nitrate, and nitrite. Aerobic and anoxic MBfRs were combined to oxidize and reduce these nitrogenous pollutions using biofilms as the catalyst for these chemical reactions. The MBfR is capable of converting ammonium (NH4) to nitrogen gas (N2), ...

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 کاملThe 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...
