Free Chlorine Tolerance <0.1 ppm Maximum temperature for continuous operation above pH 10 is 95°F (35°C). b Refer to Cleaning Guidelines in specification sheet 609-23010. c Under certain conditions, the presence of free chlorine and other oxidizing agents will cause premature membrane failure. Since oxidation
damage is not covered under warranty, FilmTec recommends removing residual free chlorine by pretreatment prior to membrane exposure.
Please refer to technical bulletin 609-22010 for more information.

Important
Information
Proper start-up of reverse osmosis water treatment systems is essential to prepare the membranes
for operating service and to prevent membrane damage due to overfeeding or hydraulic shock.
Following the proper start-up sequence also helps ensure that system operating parameters conform
to design specifications so that system water quality and productivity goals can be achieved.
Before initiating system start-up procedures, membrane pretreatment, loading of the membrane
elements, instrument calibration, and other system checks should be completed.
Please refer to the application information literature entitled “Start-Up Sequence” (Form No. 609-
02077) for more information.

Operation
Guidelines
Avoid any abrupt pressure or cross-flow variations on the spiral elements during start-up,
shutdown, cleaning, or other sequences to prevent possible membrane damage. During start-up, a
gradual change from a standstill to an operating state is recommended as follows:

Feed pressure should be increased gradually over a 30-60 second time frame.
Cross-flow velocity at the set operating point should be achieved gradually over 15-20 seconds.
Permeate obtained from the first hour of operation should be discarded.

General Information Keep elements moist at all times after initial wetting.
If operating limits and guidelines given in this bulletin are not strictly followed, the limited
warranty will be null and void.
To prevent biological growth during prolonged system shutdowns, it is recommended that
membrane elements be immersed in a preservative solution.
The customer is fully responsible for the effects of incompatible chemicals and lubricants on
elements.
The maximum pressure drop across an entire pressure vessel (housing) is 50 psi (3.4 bar).
Avoid static permeate-side backpressure at all times.

Regulatory Note These membranes may be subject to drinking water application restrictions in some countries:
please check the application status before use and sale.

Notice: The use of this product in and of itself does not necessarily guarantee the removal of cysts and pathogens from water.
Effective cyst and pathogen reduction is dependent on the complete system design and on the operation and maintenance of the
system.
