RO Membrane Preservation

Advanced Reverse Osmosis Technology

RO Membrane Preservarion - It is recommended to preserve membrane systems when the unit is out of production for more than 24 hours. Failure to preserve membranes may result in the development of biofilm on the membrane surface, causing operation problems such as increased pressure drops and lower normalized permeate flow to occur.

Also note that prior to any shutdown, RO/NF membranes need to be cleaned (dependent on the operation parameters). The system then MUST be flushed with RO permeate before the preservation solution can be pumped into the RO (at low pressure).
