This past January we began seeing unusual 'growths'
((for lack of better descriptive wording)) on the surface of panels after copper
II, they are typically observed on one end of the panels, often only a couple
panels per tankload exhibit this.
These 'growths' look like fine strands of metal of
fabric fibers, they are clustered together like someone poor shavings there, and
plated over them. If any of you recall pics of those bacteria found in that Mars
asteroid from the Antarctic, they appear similar to that (not saying we have
bacteria growing in our baths of course). Occasionally we see this out towards
the center of panels, I don't believe we have ever seen all panels in a tankload
exhibit this either. This condition is observed on one or two loads per day (out
of about 20 - 30), some days not at all.
We started seeing this in one bath (of three in
house) until recently it appeared in another bath simultaneously.
Any help on this would be greatly appreciated as
our process engineers, lab techs, and suppliers are baffled.
