each filter is matched to flowrate

How do you measure flowrate for an air driven filter ?

Most are dynamic environs which change as cells clog and flow diverts.
I imagine it would be quite the equation.
Perhaps contact a filter company pr dude?


How do you check if you reached the "matching" flow ?

By dosing with ammonia and measuring time taken to convert it all to nitrate

Where do you get the optimum flowrate for a given
air-driven sponge filter ?

a veteren can adjust air taps by eye alone to what is working elsewhere


Is it something written on the box the sponge comes in ?
yes often it is, however I'm sure a rep can assist you with this as the
answer is going to be difficult on paper.
you are better practising with them and working out your own optimums.
Slighty easier with a few hundred tanks to stuff around with


and no, every sewrage farm is not an open system!
infact most are closed too!

Closed in what sense ?
Do you dump raw sewage into the same tank
cleaned water is taken out from the system ?
Interesting...

No friend, you process batches and then dilute.
Serious go on a tour, you will get some good ideas.
Almost every filter in the hobby was developed from the sewrage industry.
Wheels and ugf and all sorts of stuff
I can see your interested and I can only say READ READ READ man!!



you have missed the point friend
and it's too late and my chicky is too hot too explain now.
later tho


There is always another day - sleep well
and please explain this when you find some time.

no prob mate, but perhaps a few less broad demands and maybe I will bother
explaining anything more than half arsed
