RO Membrane FAQs

How do I choose a replacement RO membrane?

The correct replacement membrane depends on the existing membrane model, pressure vessel size, system flow rate, operating pressure, feed water type and required permeate quality. If you are unsure, Crystwater can help review the application before you order.
What information is needed to match an RO membrane?

Useful information includes the existing membrane model, pressure vessel details, system photos, feed water source, operating pressure, flow rate, recovery target and current water quality results. This helps reduce the risk of selecting an incompatible membrane.
Can I replace an RO membrane with a different brand?

In many cases, an RO membrane can be replaced with an equivalent membrane from another manufacturer, but the size, performance range, operating limits and system conditions must be checked first. Crystwater can help compare replacement options for commercial and industrial RO systems.
What should be checked before replacing RO membranes?

Before replacing RO membranes, check pretreatment performance, feed water quality, operating pressure, recovery rate, differential pressure, cleaning history and any signs of scaling, fouling or chemical damage. If the root cause is not addressed, new membranes may fail prematurely.
