Which is primarily verified during leak checks in a reverse osmosis system?

During leak checks in a reverse osmosis system, the primary focus is on verifying the integrity of the connections. This is crucial because leaks can lead to decreased system performance, water waste, and potential contamination of the treated water. Ensuring that all connections—such as those between pipes, valves, and the membrane—are sealed properly helps maintain the system's efficiency and effectiveness.

The process of leak checking involves inspecting these connections under pressure to detect any signs of water escaping, which could indicate a failure in the seals or fittings. If leaks are present, they can compromise the entire water treatment process and lead to significant operational issues. Therefore, ensuring the integrity of all connections is key to maintaining the reliability of the reverse osmosis system.
