There's only a very small percentage of acetic acid in it, so there
shouldn't be any waste considerations.  And the material coming out of the
pipes would be a calcium acetate and water . . . along with the rest of the
cider organics.

I wouldn't use cider, but rather white vinegar.  That would have less
residual organics, and still give you about a 3% acetic acid, which should
fall below any reporting thresholds.  Then again, it's been a while since
I've been in the environmental world.  But I can tell you that from a
chemist's perspective, that would work, though it will take a lot of vinegar
. . . And you might need some "respiratory protection" to avoid the smell.

Subject: Here's one for you

We have a clogged water filtration system on one or more of our resistance
welders. Two of our engineers suggest running diluted apple cider through
the system (similar to unclogging a coffee pot, only a much bigger project).
What would the proper disposal procedure for the diluted cider be? 

Thanks!

Roger
