DOW FILMTEC SW30HR-380 Membrane

Quality parts at an exceptional value
Product Description

DOW FILMTEC SW30HR-380 delivers high boron rejection to help customers meet World Health Organization (WHO) and other drinking water standards. DOW FILMTEC SW30HR-380 elements deliver high performance over their operating lifetime without the use of oxidative post-treatments like many competitive products. This is one reason why DOW FILMTEC elements are more durable and may be cleaned more effectively over a wider pH range (1-13) than other RO elements.

The DOW FILMTEC SW30HR-380 is a premium grade seawater reverse osmosis element featuring both high active area and high salt rejection to offer the best long-term economics for seawater deslination systems.

Advantages

  • High flux reduces energy use or pressure required
  • Good rejection results in good quality water
  • High boron rejection
  • Filmtec performance and quality

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

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 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.

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.
  • Maximum pressure drop across an entire pressure vessel (housing) is 50 psi (3.4 bar).
  • Avoid permeate-side backpressure at all times.
