The TDS alarm setting on the RO system should be set at how many times the normal product TDS?

The TDS (Total Dissolved Solids) alarm setting on a reverse osmosis (RO) system is typically set at two times the normal product TDS. This threshold is crucial for proper system function and maintenance. Setting the alarm at this level allows for early detection of membrane fouling or scaling, indicating that the system's efficiency is compromised. By monitoring the TDS levels and having an alarm that triggers at twice the expected normal TDS, operators can take timely action to investigate and rectify issues before significant material degradation or operational failures can occur.

This proactive approach helps ensure optimal system performance and longevity, thereby minimizing potential downtime and costly maintenance. Monitoring TDS levels is essential in ensuring water quality and operational reliability in any RO system, making the two-fold increase in alarm setting a standard practice in the industry.
