If all tanks and final pH read the same with acid pumps running and an alarm is triggered, what should you check first?

In situations where all tanks and final pH readings are consistent yet an alarm is triggered while acid pumps are operating, it is crucial to first check the reagent level and the reagent pump prime. This is because if the reagent (acid) level is low, it will hinder the amount of acid being injected into the process, which can prevent the pH from reaching the desired levels. Additionally, if the pump is not primed correctly, it may not be delivering the acid effectively, leading to insufficient acid flow and ultimately triggering an alarm due to pH not meeting the set point.

Ensuring that the reagent level is adequate and that the pump is primed will help in diagnosing whether the acid addition system is functioning properly. A thorough check of these parameters can help identify if any corrective action is necessary before considering other potential issues.
