Nitrification in activated sludge – microbiological insight into nitrogen oxidation process
Journal Title: CHEMIK nauka-technika-rynek - Year 2011, Vol 65, Issue 3
Abstract
Activated sludge is known to be one of the most effective and popular methods of wastewater treatment. A wide range of complex biochemical and chemical processes are performed in this biocenosis, which result in obtaining a highly purified product. Nitrification, the removal of inorganic nitrogen compounds, is a crucial wastewater treatment process. Knowledge and the development of molecular biology techniques help in research performed on complex mixtures of microorganisms at the level of their nucleic acids and reveal the vast diversity of nitrifiers and other bacterial groups. The aim of this article is to provide a brief description of modern molecular methods that are useful in research into the biodiversity of nitrifiers in activated sludge and the nitrification monitoring. It was also a goal of the article to underline that biology and chemistry are closely linked mainly in the case of the biochemical processes performed in the environment.
