I am quite sure the green tint is from copper degragation. Condensate steam treatment is simply a ph adjustment to condensate water. If you are seeing green it meand big money for your mechanical contractor. Seek help ASAP>
: We experienced a similar problem using Nalco's Advanced Condensate Treatment program (ACT)
: it was due to overfeeding of the chemical. It would cause our boilers to foam up and carry over.
: We were finding green gunk in our steam traps and strainers. Also our heating coils were gunking up and freezing. After Many man-hours of blowing down the system and cleaning our traps we got rid of the so-called latest in water treatment miracles. Beware of the latest & Greatest i find if it aint broke dont f%*K with it.
:
: : We've switched chemical suppliers using a new polymer and trying to maintain between 1285-1434 as recommened by them. What we are experiencing is boilerwater with a green tint and when the steam drum was opened,even the inside had a very slight greenish film. This does not sound normal.
: : Has anyone else ever experienced this? even the meter recommended by them does not read that high so they told us to dilute boiler sample by 50% and multiply results by 2.
: : SOMETHING IS NOT RIGHT HERE.
