Hi guys, not sure if I'm in the correct category here, but have read the stock pot / waste treatment threads and have a question.
The thread instructed to increase the pH of waste acids to 2.5 before adding to the final treatment drum that contains solid iron. My understanding is that this drum is used to cement all metals below iron out of the solution so you are left with mostly iron in solution.
What is the reason for increasing the pH to 2.5 ?
