Mechanism for Simultaneous Nitrification/Denitrification
The operating characteristics of six full-scale wastewater treatment plants using the staged, closed loop bioreactor process known as orbal were evaluated to determine the degree of simultaneous biological nutrient removal (SBNR) occurring. Low effluent total nitrogen concentrations indicate that simultaneous nitrification and denitrification occurs reliably in these facilities. The use of SRT ...
متن کاملNitrous Oxide Nitrification and Denitrification
The isotopic signatures of N and O in N2O emitted from tropical soils vary both spatially and temporally, leading to large uncertainty in the overall tropical source signature and thereby limiting the utility of isotopes in constraining the global N2O budget. Determining the reasons for spatial and temporal variations in isotope signatures requires that we know the isotope enrichment factors fo...
متن کاملStable-Isotope Analysis of a Combined Nitrification-Denitrification Sustained by Thermophilic Methanotrophs under Low-Oxygen Conditions.
To simulate growth conditions experienced by microbiota at O(inf2)-limited interfaces of organic matter in compost, an experimental system capable of maintaining dual limitations of oxygen and carbon for extended periods, i.e., a pO(inf2)-auxostat, has been used. (sup15)N tracer studies on thermophilic (53(deg)C) decomposition processes occurring in manure-straw aggregates showed the emission o...
متن کاملNitrous Oxide Sources in Aerobic Soils: Nitrification, Denitrification and Other Biological Processes
Nitrous oxide (NrO) production in aerobic, intact soil cores collected from two forest sites was partitioned into different sources of N,O by subjecting soils to specitlc inhibitors during short-term incubations. We used acetylene (IO Pa) to selectively inhibit N,O production by nitrifiers, 100 kPa (100% v/v) 0, to inhibit N,O production by denitrifiers, and sterilixed soil to evaluate chemical...
متن کاملInfiltration mechanism controls nitrification and denitrification processes under dairy waste lagoon.
Earthen waste lagoons are commonly used to store liquid wastes from concentrated animal feeding operations. The fate of ammonium (NH) and nitrate (NO) was studied in the vadose zone below earthen-clay dairy farm waste lagoons using three independent vadose zone monitoring systems. The vadose zone was monitored from 0.5 to 30 m below land surface through direct sampling of the sediment porewater...
