Peggy:

I'll rise to the challange. You argue that a holding tank needs lots
of ventillation to prevent odors. Most tanks don't have a large vent
hose so little exchange of air occurs and they are non-arobic.

Do you know of any system that uses a small air pump to bubble air
through the sewage to oxygenate it. Seems to me a small aquarium pump
would work but they all run on 115 volts and are noisy. This addition
would also require another hole in the tank but that is not hard to do
and would be worth the effort if the odors were eliminated.

Hi Bill, I'll save Peggie the trouble and post her previous answer to the
same question:

Roger Long wrote:
Peggie,

I see some rather pricey system for pumping air into holding tanks to
aerate them. I'd like to try rigging up my own. How much air does it
take? Is there a critical amount below which nothing useful happens
or does any air help?

The Groco Sweetank pump moves 1.7 liters of air/minute, which is about
the minimum that'll work. Two things are important: a sufficient amount
of air to aerate the contents, and piping to distribute it throughout
the tank. Otherwise it'll only push foul gasses out the vent all the
time instead of only when the head is flushed.

You can see the compete manual for the Sweetank he
http://www.groco.net/parts/data/622.pdf


I'd like to avoid the 12 volt drain. Since we are in an area where
there will usually be wake motion, I have an idea for boat motion
powered pump.

I don't think it would produce enough air. The Sweetank requires only 3
watts of 12v power...not much of a battery drain. If even that's too
much for your current 12 resources, a relative small solar panel would
replace the drain on your battery.

It's price of $150-200 seems expensive...but the purchase price is
offset by what you're spending for tank products now, 'cuz a properly
aerated tank requires nothing else. So depending on how much you're
spending for tank products, the Sweetank can pay for itself in just a
few years.

No matter how many times you've had it, if it's
offered take it, because it'll never be quite the same again.

C'mon people. How about a sanitation question or two to cheer me

Good grief!! You really do think that you are superior, don't you?

If you were half as bright as you think that you are, then you would realise
that Harry *had* looked at the headers.

I hope that the members of Harry's ng don't assume that all asa posters are
as stupid as you are.

Nope, don't give a rat's ass! Having too much fun in real life not to care!

Has kkkaty sailed the Atlantic Ocean twice since February? (Didn't think
so...)

As far as her "new moniker". All I can say is she must have added a much
needed "spell-checker".

As long as your happy with her "services", then why would I care? :-)
