Summary for anode bags required Discussion
Anode bags required for power acid tank is the core question here: the poster asks whether lead anodes in a power acid tank with 9-10% sulfuric acid and reverse current need bags, and why. The thread excerpt shown contains only the question, so no named expert answer or detailed explanation is available to confirm a definitive yes or no. Based on the wording, the issue is about whether bags are needed to contain anode sludge or prevent contamination in this acid environment, but the source provided does not include the actual technical response. Because no answers are present in the excerpt, the safest takeaway is that the thread raises the need for anode bags in a sulfuric acid reverse-current setup, but the final recommendation cannot be determined from the supplied text alone.
We have power acid tank with 9-10% by vol. sulfuric acid concentration and reverse current for our application.Do we need the bags
⇦ huh? for lead anodes ? if answer is yes why do we need bags for anodes?.

A. Have you considered using carbon anodes. I try not to suggest lead anodes because of the possiblility that any dissolved lead in solution will then become effluent
