is a pity to see such pseudo-scientific nonsense being posted in a technical forum such as this. The term "anaerobic" describes a condition in which there is an absence of free oxygen. Water contains chemically-bound oxygen. Anaerobic conditions are easily created and maintained in a myriad of processes. End of story.

Ing.Tiziano Zampollo, my criticism was not directed at your article, but rather at the first comment. It was my first time contributing to these fora, and I should have replied to the comment rather than added to the the main thread. I shall be more careful from now on. ;)

Dear John, Your points of view are welcomed! ( a little less the form chosen....though).
You've missed the point: we're dealing with wastewater not pure water. To be biological, we need bacteria. To have live bacteria You need Oxygen, either free or bound. Anaerobic bacteria use chemically bound type to breathe and substrate as food. At those ORPs (-400 mV) free oxygen is zero, and chemically bound oxygen is consumed; nitrates become N2 and SO4 becomes H2S or elementar S (that's the scope of the "anaerobic path chosen"). I assume You're not into WWTP, whereas UASB, EGSB, ABR and HEABR are in use ever since. Such process is probably one of that myriad of processes You mention.
BTW, thanks for taking time to read and comment.
