| These conditions raise the potential for nitrification, leaching, denitrification, or runoff losses. |
|
| The remaining processes that could account for the rapid depletion of riverine nitrate are denitrification and microbial assimilation. |
|
| Losses are experienced mainly through effluents but also by denitrification, sediment formation, and loss to the atmosphere. |
|
| Methanol is also being used increasingly in new applications, such as wastewater denitrification, biodiesel, gasoline blends and fuel cells. |
|
| Emissions of nitrous oxide from agricultural soils are primarily due to the microbial processes of nitrification and denitrification in the soil. |
|
| This forced industry to move ahead rapidly with developing air denitrification processes. |
|
| The process, called denitrification, results in a loss of nitrogen from the soil. |
|
| Water table management may facilitate denitrification in the off-season. |
|
| Nitrate ion has been shown to act as a terminal electron acceptor in the denitrification process in flooded soils and has been suggested to play a similar role in plants. |
|
| In an anaerobic environment, xylenes are biodegradable in denitrification conditions. |
|
| Anaerobic fixed-bed reactor can achieve sulfur autotrophic denitrification. |
|
| An increase in export production in the vicinity of eastern boundary currents will intensify the suboxic conditions naturally found there and will increase nitrous oxide production by denitrification. |
|
| Due to impeded drainage, the denitrification potential of the majority of soils in Northern Ireland is relatively high, reducing the nitrate concentration in soil and, therefore, the amount of nitrate susceptible to leaching. |
|
| We evaluated differences in denitrification potential and a suite of other soil biological and chemical properties in soil samples taken from organic, integrated, and conventional treatments in an experimental apple orchard. |
|
| The study is expected to produce a new method for the identification of denitrification activity in aquifers where analysis of nitrate concentrations would otherwise be inconclusive. |
|
| The main purpose of this study is to investigate the application of novel gas-permeable membrane bioreactors for cost-effective nitrification and denitrification in wastewater. |
|
| The gas is a by-product of the biological denitrification process in anaerobic environments and of the biological nitrification process in aerobic environments. |
|
| These organic compounds can also serve as the energy source for biological denitrification processes in which nitrate is converted to nitrogen gas in the absence of molecular oxygen. |
|
| Nitrous oxide is emitted during the denitrification process. |
|
| The final step in the cycle is denitrification, in which still one more group of bacteria convert nitrate to nitrogen gas, releasing it back into the air. |
|
|
|
| If soil becomes waterlogged from too much rain, denitrification can occur. |
|
| The wastewater is discharged into the public sewage system and treated in the municipal wastewater treatment plant, which is a biological plant with nitrification and denitrification. |
|
| McKenzie notes that in areas where there has not been more than five or six inches of rain and the water can drain away, the denitrification should be minimal and the crop should start greening up. |
|
| Simultaneous nitrification and denitrification with an upflow fixed bed reactor applying clinoptilolite as media. |
|
| The steps, which are not altogether sequential, fall into the following classifications: nitrogen fixation, nitrogen assimilation, ammonification, nitrification, and denitrification. |
|
| Increased merits in terms of both initial costs and running costs were pursued through the elimination of the need for denitrification equipment. |
|
| This technique is designed to promote biological activity that speeds up the bio-degradation of putrescible materials and causes nitrification of the ammoniacal nitrogen and thus denitrification of the nitrates. |
|
| Without denitrification, however, the Earth's supply of nitrogen would eventually accumulate in the oceans, since nitrates are highly soluble and are continuously leached from the soil into nearby bodies of water. |
|
| Building wetlands around the rivers would encourage the natural denitrification that occurs in such ecosystems, and buffering rivers with grasses to absorb the nitrates would help a lot as well, Dr. Scavia said. |
|
| Organically farmed soils exhibited higher potential denitrification rates, greater denitrification efficiency, higher organic matter, and greater microbial activity than conventionally farmed soils. |
|
| The above models and calculations indicate that compliance with the objective of a maximum of 50 mg per litre of nitrates in groundwater at watershed level and considering denitrification is ensured. |
|
| Alberta Agriculture and Rural Development is reporting signs of denitrification in southern Alberta crops due to excessive spring moisture conditions. |
|
| Further, wet or anaerobic soils also lose nitrogen through denitrification, releasing the greenhouse gases nitric oxide and nitrous oxide. |
|
| The formation is either through nitrification or denitrification or nitrifier denitrification or combination of all these three processes. |
|
| The principle pathway for nitrification may have been nitrifier denitrification. |

| Consequently, power companies in many European countries are now taking steps to add denitrification and desulfurization equipment to their power plants. |
|
| The E-G model does not account for denitrification or N immobilization. |
|
| The business has extended to industrial wastewater and municipal wastewater treatment, sewage treatment, flue gas desulfurization and denitrification systems. |
