As usual, having searched the web, there's loads of general info but little
in the way of specifics.
I'd like to know, roughly, the air flow rate per cubic meter needed to be
pumped though a septic tank, to crate anaerobic reaction. ....200
litres/hour per cubic meter?....2000litres litres/hour per cubic
meter???....I did read somewhere the temperature must be no lower than 10
C......that's as far as the specifics went. Cheers
We have another tank which contains only liquid, through which I want to
pump air. A web site was advertising a system that used annaerobic reaction
in the main tank, and aerobic in the second stage, prior to watercourse
discharge. It's for this aerobic reaction I want to find out more info.
No, it's a septic tank ie, the liquids soakway (?)
motor on the air compressor, bubbling air continuously
through what I guess was a 500 gallon'ish aerobic chamber.
They were off-mains and had tried to get by only running the
compressor when they ran the generator. It started to smell
indicating it had gone anaerobic. Sorting out the electrics
so that the compressor ran 24x7 fixed it.
I guess the proper answer is to use a DO meter and adjust
the air accordingly, as what is needed should vary with
temperature and effluent flow. However, a big tank should
even things out.
I don't know if that helps - but may be useful as an
indicator of the amount of compressor power/ airflow that
may be needed.
