A customer alerted us to an issue with their acid-based anodic nickel stripper. The issue had been ongoing for at least a couple of months and they had tried many different things to solve the issue.
One of the issues was the automatic backwash filtration system had been down for an extended period. It was thought that was the main culprit, based on the appearance of the strip solution showing a great deal of floating solids that would settle to the bottom when there was no circulation.
Filtration Fixed, but…
The filtration system was fixed, and the customer decided to dump and make up a new strip bath. For the first few days, the strip seemed to be back to normal. However, after about three days, the bath started to appear murky again and the stripping performance was well below expectations.
