Air bubbles

[Nova 8]

I'm sorry but you have read wrong, again call any waste water treatment plant, or any plant that needs to oxygenate water to return it to a lake or stream, they all use bubbler sytems, in extreme cases the will use batch reactors that use misters, concept is the same however. Also the bubbles have the same concentration of oxygen as the atmosphere, about 21%

the fact that they are bubble does not matter, you are correct that its all about the surface area, bubbles increase surface area as they each have their own, added up its is quite significant

FACTS

I never said the air inside a bubble contains a lesser % of oxygen then the air above the tank (20.98% I learnt in school), but I said a bubbles maximun oxygen volumn which is limited by its small size doesn't compare with the avalible % of oxygen of the total surface area (just not stated that well).

I await your email.
Also about the "FACTS" thing, what a load you could be anyone just typing crap, ohh the joys of the internet. Don't try a push your "theroey" until you show actual real FACTS.

It does not matter what the total volume in the bubble is, only the concentration, this is what drives gas tranfer.

The email has been sent, i'll say it here just so anyone following this knows, I sent the procedures and background notes this evening and will send the data tomorrow, I dont have it on my home computer.

They are facts, period

It is not theory it is proven. I have the privelage of working with some very qualified people in this field. If you would care to look into it they are California Department of Water Resources (DWR) employees. You can look them up and email them and they will more than likely be happy to answer your questions. Dr Ed Dammel, Dr John Johnston, and Dr Ramzi Mahmood. All are DWR employees and also University professors at CSUS. If you would like an email address where you can reach them, pm me, or go to www.ecs.csus.edu and get their emails for yourself, I only ask that if you email them please be polite and professional.

You can believe what you want, but as far as I can tell what you believe has no basis in reality, you refer to the joys of the internet but I have no reason to believe based on what you have said that you get your information from anywhere else.

I will see if I can dig up some photos from an aeration tank at a treatment plant, where the use plain old bubbles to aerate the water

if anyone else is interested in seeing the results of the gas transfer lab pm me and I will send it out tomorrow afternoon

in case you were wondering why i keep referring to waste water treatment, it is because the bacteria that consumes organic material has more influence on the DO concentration than any other organism. In waste water treatment plants the bacteria only exists to consume waste, in order to for the bacteria to consume the waste there must be oxygen, in order to efficiently oxygenate the water bubblers are used................ does any of this sound familiar

sent the data and the results to Nova, I had them here after all. Again if anyone else would like to see it let me know. The results are pretty clear

I have opened up to two word documents, You said its an excel sheet right? I just found out I dont have excel on my computer right now so I'm going to go to a mates right now to get it.
Just so you know, if I do msg the people you told me to, I will be polite and treat them with the repect they deserve.

I was just breezing through the word document and I dont understand alot of the math but I do understand how to read the charts and I understand the writing just fine, so I'm hoping that will be enough, but if I get stuck I'll pm you like you said to explain it.

The equations only seem hard because you are probably not familiar with what the variables are. The spreadsheet that I sent you has all the math done and the results are graphed so you can see the results visually.

for anyone who is curious, the math invoolved is a first order differential equation. It is exponential as you may expect, or may not depending on how well you understand gas transfer. Basically the less oxygen in the water there is the faster the rate will be, when it comes close to saturation levels its slows to a crawl.

It is not theory it is proven.

Just quickly about this, to me religion is a theory and evolution is proven, but if you ask the church it will be the opposite way around, this is what I meant.
BTW if I read through all this info and am convienced 100%, I will not only admit to it, but I'll be right there with you spreading the word.

Okay, well the church is founded in faith, and evolution in evidence. I am saying "proven" for the same reason, as there is scientific evidence to back it up. Although the evidence for evolution is not conclusive, in this case its hard to argue otherwise after conducting the experiments yourself. It is an easy experiment to do, just difficult to get a lab grade DO meter, and not many people have the ability to deoxygenate water at will
