Anammox Process: 7

2021
Today one of the most important environmental problems in the world is the proliferation of wastewater. The nitrogen is an important component that can be found in a wide range of concentrations and chemical forms. In the last decades, the nitrogen cycle has been re-evaluated, thanks to the anammox bacteria discovery.

Sewage Treatment with Anammox

Science, 2010
Organic matter must be removed from sewage to protect the quality of the water bodies that it is discharged to. Most current sewage treatment plants are aimed at removing organic matter only. They are energy-inefficient, whereas potentially the organic matter could be regarded as a source of energy.
