What could happen if a Total Chlorine sample is collected before the minimum operating time of the RO?

When a Total Chlorine sample is collected before the minimum operating time of the reverse osmosis (RO) system, the results could be falsely negative. This is primarily due to the fact that during the initial period of operation, the RO system may not have adequately filtered out all chlorine present in the water. If the sampling occurs too early, any residual chlorine may still be present, but due to insufficient time for the system to equilibrate properly, the sampling may inaccurately suggest that the chlorine levels are lower than they actually are.

This can lead to a misunderstanding of the system's ability to effectively remove chlorine, potentially causing issues if action is not taken based on incorrect test data. Therefore, it's crucial to adhere to the guidelines regarding minimum operating times to ensure that sampling yields accurate and reliable results regarding the presence of chlorine.
