Nitrification: A biological process, during which nitrifying bacteria convert toxic ammonia to less harmful nitrate. It is commonly used to remove nitrogen substances from wastewater, but in lakes and ponds it occurs naturally.

nitrification
Sequential oxidation of ammonium salts to nitrite and nitrate by micro-organisms.

Nitrification: biochemical oxidation of ammonia (NH3), ammonium (NH4), or atmospheric nitrogen (N) to nitrate (NO3) or nitrite (NO2).

Nitrification - The conversion of nitrogen organic compounds to inorganic compounds of nitrogen. This conversion is accomplished, in the main, by bacteria. [Applied and Environmental Microbiology; v60; 3307-3314; 1994.

nitrification
the conversion of nitrogenous matter or free nitrogen into nitrates and ammonia by bacteria.
non-ionic surfactants ...

nitrification. The biochemical transformation of ammonium nitrogen to nitrate nitrogen.
nitrification inhibitor. A chemical that slows down the conversion of ammonium to nitrate nitrogen.

Denitrification: The biological reduction of nitrate to nitrogen gas by denitrifying bacteria in soil.

D denitrification
Definition (english only)
1) The loss of nitrogen from soil by biological or chemical means. It is a gaseous loss, unrelated to loss by physical processes such as through leachates. 2) The breakdown of nitrates by soil ...

Nitrification The biological oxidation of ammonia and ammonium sequentially to nitrite and then nitrate. It occurs naturally in surface waters, and can be engineered in wastewater treatment systems.

denitrification the microbial production of N2 and N2O from nitrites and nitrates, mostly anaerobic, but not always ...

0 ppmdenitrification The biochemical conversion of dissolved nitrate and nitrite nitrogen in soil or water to nitrogen gas. desalination The removal of dissolved salts, such as sodium chloride, from water.

ultimate BOD A measure of dissolved oxygen required for biological oxidation of carbon and nitrification of organic matter in wastewater. See BOD.

Nitrification The conversion of nitrites to nitrates, usually by microorganisms. The term is commonly used to describe the process of conversion of ammonium ions via nitrites to nitrates.
