RO Membrane Compaction
Advanced Reverse Osmosis Technology
RO Membrane Compaction - Physical compression
of the membrane. This compression results in a decrease in flux.
The rate of compaction is directly proportional to an increase in
temperature and pressure. Compaction
occurs naturally over time requiring a greater feed pressure. Feed
pumps are sized to the pressure requirements of the third year.
Compaction is permanent and can occur quickly in CA
membranes if operated at high pressures for any extended period
of time. PA membranes have greater structural strength and can be
operated at higher than normal pressures with little concern to
compaction. Change as a result of compaction is expected for CA
and TFC membranes during the first 200 hours of operation.
