Reverse Osmosis Membrane Preservation for RO & NF Membranes Print E-mail

RO Membrane Preservation - If a reverse osmosis system is shut-down or out of production for more than 24 hours it is highly recommended that the RO membranes are cleaned and then correctly preserved. Failure to preserve the RO membranes may result in the development of un-wanted bacteria and biofilm on the membrane surfaces. This can lead to significant operational problems such as increased pressure drops and reduced normalized permeate flows.

It is also important to note that prior to any plant shutdown, reverse osmosis and nanofiltration membranes need to be carefully cleaned using a high quality membrane cleaner, the precise cleaning procedure will be dependent on the operational parameters of the system. The system MUST then be flushed with permeate before the preservation solution can be pumped into the reverse osmosis system, usually at low pressure.
