The number of culturable nitrifying and denitrification bacteria, ammonifiers bacteria and azotobacteria in a sample was determined by counting colony forming units (CFU).
2]O in constructed wetland is mainly produced by nitrification, denitrification, and denitrifier denitrification (Wrage et al.
2]O) emissions from agricultural systems are thought to result principally from the microbial-mediated processes of nitrification (the oxidation of ammonium to nitrate) and denitrification (the reduction of nitrate to [N.
In the biological process, nitrogen removal is achieved through nitrification by autotrophs and denitrification by heterotrophs; i.
Increased merits in terms of both initial costs and running costs were pursued through the elimination of the need for denitrification equipment.
In addition to these achievements in power output and generating efficiency, increased merits in terms of both initial costs and running costs were pursued through the elimination of the need for denitrification equipment; together these benefits enable a faster investment return than with the 380kW system.
It is subjected to environmental losses like volatilization denitrification leaching and runoff.
The environmental protection minister, Zhou Shengxian, told an annual government meeting that authorities last year banned 7 million high-emission vehicles from the road, shut down 50,000 coal-fired furnaces, installed denitrification and desulfurisation equipment in power plants and factories, and added new sewage treatment plants, Xinhua said.
The formation is either through nitrification or denitrification or nitrifier denitrification or combination of all these three processes (Horak, Siska 2006).
Conventional nitrogen removal processes involve nitrification/denitrification, which involves the conversion (through aeration) of ammonium to nitrite and to nitrate followed by denitrification of nitrate to nitrite and finally to nitrogen gas with the use of organic carbon compounds as an energy source.
ESN's controlled-release technology delivers the right amount of nitrogen to crops throughout the growing season, resulting in better crop quality, higher yield and protecting nitrogen from loss to leaching, volatilization and denitrification.
