Hi,
We are seeing acetone in the wastewater (spent tank) and trying to find out the source of acetone.
FYI:
1) Our product contains IPA.
2) Based on the results we got from EPA lab (6 months historical data), we see acetone ranging from 1 to 7 ppm in wastewater.
3) Plant is not dumping acetone contaminated water in the spent tank.
4) It’s not an EPA lab doing anything wrong. We tried 2 different EPA labs and they all got same acetone results.
5) We don't have a procedure for waste water sample collection from spent tank and sample shipment to EPA lab for testing.
I can't think of anything else to find the source of acetone. Anyone has any suggestions or has an experience with this type of problem.
Thanks,
|

Hi,
Just a thought - I believe industrial grade isopropyl alcohol (IPA) can contain several 100ppm of acetone . Steve
