What does RO membrane replacement mean in practice?
The decision is made after comparing retention and flow under similar conditions when new prefilters and the correct pressure do not restore the parameters.
When does it matter?
The low flow from the faucet itself may be due to the tank or valve, not to a worn diaphragm.
Which solutions are related to it?
Before replacement, the feed, permeate and concentrate are measured and the new membrane is hygienically installed and rinsed down the drain.
