Lesson 8: Nitrification and Denitrification

Organic matter containing nitrogen, e.g., protein and nucleic acid, also biodegrades to release ammonia. Releasing this ammonia into receiving streams has a direct toxic effect on fish and other animals and, in addition, causes significant oxygen depletion. Nitrate is regarded as an undesirable substance in …

Scientists have known for a while that climate change is making the world’s oceans more ,acidic,. When carbon dioxide dissolves in the ocean, it reacts with the water to form carbonic acid. Ocean acidification causes many problems, including interfering with the shell-building abilities of crabs and other organisms that require calcium carbonate to build.

Acid Mine Drainage - an overview | ScienceDirect Topics

AMD is the largest source of environmental problems caused by the mining industry. AMD is the result of tailings and overburden being exposed to air and water. The oxidation of pyrite and other sulfide minerals in the presence of oxidizing bacteria results in the production of acids. This oxidation process occurs slowly in all soils.

Acidic and basic contaminants in amine treating

Higher molecular weight ,organic, acid anions ,come, from the hydrolysis of higher molecular weight nitrile compounds. Ammonium ion produced by the hydrolysis reaction will yield an H+ to the amine; the resulting ammonia molecule is then stripped from solution by steam in the regenerator and it accumulates in the overhead condensing system.
