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


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.
