Hi everyone!
We have a BBT tank appears to have beer stone (correct me if I'm wrong).
I have run out of ideas, we have runned many cycles of chlorinated caustic, nitric acid and phosphoric acid.
Concentrations were 4-5% for 60min.
After 2 cycles we used only the acids for about 5 times more, we used cold and hot temperatures also.
I have some samples that can give you an idea.
After the first CIP
Later
And finally we got there
The organics seems to cleaned out nice.
But I'm guessing the rest won't come off with CIP.
How bad is it?
Maybe scrub it by hand, with what?
Any opinions would be great.
