What action is taken if total chlorine testing after the 2nd carbon tank shows results above the action limit?

When total chlorine testing after the second carbon tank shows results above the action limit, stopping all treatments is a critical response. Chlorine can be harmful to downstream processes, particularly in reverse osmosis (RO) systems where chlorine can damage membranes and adversely affect performance. By halting treatments, you prevent potential damage to the RO system, ensuring that the integrity of the membranes is maintained, and that water quality performance does not deteriorate.

Taking this action allows for an immediate assessment to identify the source of the elevated chlorine levels, making it an essential step in protecting the overall water treatment process. Once corrective measures are identified and implemented, the system can then be safely restarted, ensuring that all safety and operational protocols are followed to avoid any long-term harm to the infrastructure.
