What is the minimum duration for which an RO system must run before testing?

For an RO (Reverse Osmosis) system, the minimum duration before testing is 15 minutes. This timeframe allows the system to stabilize and reach a consistent operating state, which is crucial for obtaining accurate readings of the water quality and performance metrics.

During this initial period, any residual air bubbles in the system can disperse, and the membranes will become fully hydrated with water. This ensures that the measurements taken afterward reflect the actual performance of the membrane and the overall system, as opposed to transient behaviors that could distort results if testing were conducted too soon.

Testing too early could lead to misleading data, impacting decisions regarding the operating status of the system and potentially resulting in improper maintenance or oversight. Therefore, the 15-minute minimum is set to ensure reliability and accuracy in testing the RO system's efficiency and effectiveness.
