High Quality Industry RO Membrane Water Purifier BW30-4040 Membrane for Drinking Water
Improved seawater reverse osmosis elements offer the highest productivity while maintaining excellent salt rejection.
• SW30 membrane elements have the highest flow rates available to meet the water demands of both sea-based and land-based desalinators.
• SW30 elements may also be operated at lower pressure to reduce pump size, cost and operating expenses.
• Improved seawater membrane combined with automated, precision element fabrication result in the most consistent product performance available.

Refer to Cleaning Guidelines in specification sheet 609-23010.
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, it is recommended that residual free chlorine be removed by
pretreatment prior to membrane exposure. Please refer to technical bulletin 609-22010 for more 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.
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 operating state is recommended as follows:
Feed pressure should be increased gradually over a 30-60 second time frame.
Cross-flow velocity at set operating point should be achieved gradually over 15-20 seconds.
Permeate obtained from first hour of operation should be discarded.
