Thermo Scientific Barnstead Pacific RO
Pure water system
Your pure water system is equipped with automatic flushing. Flushing is carried out when the
system is switched on, at the end of each production, and also every 12 hours. For this, rinsing
solenoid valve (V3) is opened and the strong flow of water across reverse osmosis module (F2)
sweeps coarse particles and other contaminants away from the surface of the membranes and
carries them with it to drain.
This automatic flushing has a positive effect on the service life of the reverse osmosis module.
An additional advantage of automatic flushing is that it prevents bacterial growth from occurring
in the reverse osmosis module when the system is at a standstill for a long time. For this reason,
we highly recommend that you leave the system switched on over the weekend and during holi-
day times, so that the 12 hour flush can effectively guard against bacterial growth.
