The SHARON (Single reactor system for High activity Ammonium Removal Over Nitrite) wastewater treatment process is a combination of two already used nitrogen removing reactions. One process utilizes fast growing nitrifiers utilizing nitrification of ammonia to nitrite and Anammox which is the denitrification of nitrite to atmospheric nitrogen ...
The disadvantages of gas nitriding are: Reaction kinetics heavily influenced by surface condition – an oily surface or one contaminated with cutting fluids will deliver poor results; Surface activation is sometimes required to treat steels with a high chromium content – compare sputtering during plasma nitriding
The two main chemicals needed for the metabolism of anammox bacteria to function are ammonia and nitrite. Nitrate and nitrite are produced by microorganisms within wastewater treatment facilities as a result of sewage treatment. The chemical compound ammonia monooxygenase converts ammonia in wastewater into nitrite during the nitrification process.
Since denitrification can remove NO 3 −, reducing its leaching to groundwater, it can be strategically used to treat sewage or animal residues of high nitrogen content. Denitrification can leak N 2 O, which is an ozone-depleting substance and a greenhouse gas that can have a considerable influence on global warming.
Nitrogenous dissolved solids (amino acids, ammonia, etc.) are similarly converted to biological floc or oxidized by the floc to nitrites, nitrates, and, in some processes, to nitrogen gas through denitrification. While denitrification is encouraged in some treatment processes, denitrification often impairs the settling of the floc causing poor ...
Nitrogen cycle. Nitrification is the biological oxidation of ammonia to nitrate via the intermediary nitrite.Nitrification is an important step in the nitrogen cycle in soil.The process of complete nitrification may occur through separate organisms [1] or entirely within one organism, as in comammox bacteria.
