ITS JUST THE AIR FOLKS, JUST THE AIR

Well here we go again. I've been very lax about posting my missives. My associates believe that I have been derelict in my duties, as a person of blogs, for not having posted more "informatives" (I kinda like that title) on this site.

You need to understand the difference between the word "aerobic" or "requiring free oxygen" vs what I call "atmospheric oxygen". "Atmospheric oxygen" means being in an atmospheric like environment. This is a crucial difference when discussing aerobic treatment devices. The crucial difference is efficiency.

Aerobic bacteria, or bacteria functioning metabolically with an aerobic metabolism, need free oxygen but they need it instantly and constantly to be efficient at digesting or metabolizing organic compounds (stuff). Aerobic devices that depend on dissolved oxygen (DO) in water to supply the "free oxygen" to aerobic bacteria (we trap within these devices and force them to work for us) are not efficient. Why you ask because I have your undying attention? DO is not constant within water. There is a mosaic of "free oxygen" in the water (7mg/l in water is considered saturated). Not very much oxygen by the way and saturated DO does not exist in most aerobic devices (except mine).

The DO is not a constant in every measurable amount of the water. The bacteria are not in constant contact with the "free oxygen" at all times as they would be if in atmospheric conditions. They have to wait (like waiting for a bus) until the "free oxygen" molecule happens along (again like the bus) for them to metabolize the oxygen and organic compounds (stuff). Luckily bacteria don't appear to have the same frustration potential as humans (again like the bus).

So if we want efficiency in "aerobic treatment, we don't want the treatment to merely be aerobic, we want it to be atmospheric like. Welllllllll, guess what? There are such devices that have atmospheric like conditions within them, while they sit on the bottom of your septic tank.
They are the various Pirana System models.

They are quite small, three feet tall and twelve inches in diameter or less, and very easy to install. They use very little electricity, require 2 cfm or less of air at less than 4 psi. Why small, easy and use little energy? Because the bacteria live in "atmospheric like oxygen" conditions within the devices. This means the bacteria have instant and constant access to oxygen to metabolize organic compounds (stuff). This means efficiency. Efficient allows for reduced size but increased effectiveness.

So when you think of aerobic treatment, qualify your thinking and think "atmospheric like" aerobic treatment. You now understand the difference and have a choice.

Well, thanks for stopping by. Remember, unlike my wife, that its out there so check your shoes before entering the house.
