Simultaneous removal of nitrite and organics in a biofilm-enhanced high-salt wastewater treatment system via mixotrophic denitrification coupled with sulfate reduction

Nitrogen 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...

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...

Coupled Anaerobic Baffled Reactor (ABR)/Activated Sludge Treatment of Synthetic Wastewater with High Concentration of Sulfate and COD

A synthetic wastewater with high concentration of sulfate and COD was treated in anaerobic baffled reactor (ABR) coupled with an activated sludge. The work was accomplished in two phases. In the first phase, the concentration of sulfate was kept constant at 500mg/l, but COD concentration was increased from (3000mg/l to 6000mg/l), consequently, COD and sulfate removal in ABR reached to 80% and 9...

salt inhibition effects on simultaneous heterotrophic/autotrophic denitrification of high nitrate wastewater

denitrification of high- nitrate high- salinity wastewater is difficult due to plasmolysis and inactivation of denitrifiers at high salinity conditions. in this study, the effects of salinity and empty bed contact time (ebct) on simultaneous heterotrophic and sulfur based autotrophic denitrification of synthetic wastewater were evaluated in an up flow packed bed reactor .the reactor was filled ...
