  1. 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.

    1. 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. ;)

    2. 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.
       

  2. The anaerobic is a simple view of the mind of a person who discovered a State of putrefaction advanced, quite incomprehensible to him, whom he named as opposed to an aerobic State anaerobic.
    At this time we only discovered the aerobic State and the scientific community welcomed his vision of opposition.
    Except that the following elements contradict this approach:
    Water, H2O contains oxygen. Where there is water there is therefore necessarily oxygen. Even if there is a 0.001%.
    The atmosphere is totally aerobic at several levels of its layer or it has been shown that there was life and in proportion. 21% on Earth, and decrease gradually and as we climb in altitude.
    Those who speak of the anaerobic describe a medium often inaccessible and distant in the most remote places of our planet, there or it is of course impossible to check.
    Some describe this environment in purification of wastewater.
    Except that it is hard to admit that where there is water in aerobic condition with oxygen, can settle an anaerobic State without oxygen.
    How is this medium for foothold?
    How does this environment persist?
    What is the trigger for creation of this State?
    How and which would be able to delineate in oxygen aerobic environments, the component of the safety barrier of the aerobic State, of the anaerobic State in a liquid in motion?
    By the principle of the existing atmospheric conditions on Earth, water and air are in perpetual motion. Because of this principle oxygen is regenerated continuously even in the remotest corners of our land.

    See scientific communication: anaeroby does not exist on earth, anaerobic can not exist on our planet

    1. Thanks for insights, Jean Marius. As a matter of fact You are 100% right. There are definitions, rules and conventions.
      To live on earth and deal with other human beings we also need to accept conventions: today the 99% easily becomes 100% at people's eyes...
      ...whereas the lack of free oxygen is considered anoxic and the lack of both free+bound oxygen is called anaerobic. Tolerances and scale, that's what I mean.
      We are into industrial treatment, we're not into analytical lab theory. IMHO 0,0000000% as well as 100,00000% are set points, working hypo, not Always achievable in the real industrial world.
      Just my thought
