RO & Sea Water Membranes

Product Details:

Lewabrane® RO S085 HR 4040 elements are spiral-wound, composite polyamide membrane elements designed for the desalination of seawater. The S085 HR membrane is characterized by an extremely durable, highly cross-linked polymeric separating layer suitable for high salinity, high pressure applications. The Lewabrane® RO S085 HR 4040 membrane element is recommended for single pass applications where stable salt rejection performance during the expected operating lifetime is an important consideration.

Product Details:

The A-Series, family of proprietary thin-film reverse osmosis membrane elements, are characterized by high flux and high sodium chloride rejection. AG Standard Brackish Water Elements are selected when high rejection and operating pressures as low as 200 psi (1,379 kPa) are desired. These elements allow moderate energy savings, and are considered a standard in the industry.

Product Details:

FILMTEC brackish water reverse osmosis membrane elements provide consistent system performance in light industrial applications.

• Filmtec BW30-8040 is an industry standard for reliable operation and production of high quality water. 
• Filmtec BW30-2540 elements are designed for systems smaller than 1 gpm (0.2 m3 /h) offering a hard shell exterior for extra strength.

Elements with a hard shell exterior are recommended for systems with multiple-element housings containing three or more membranes, as they are designed to withstand higher pressure drops.

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 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.

Please refer to the product technical manual.

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. Refer to FILMTEC Reverse Osmosis and Nanofiltration Element Three-Year Prorated Limited Warranty (Form No. 609-35010)
• 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 static permeate-side backpressure at all times

Product Stewardship:

• DuPont has a fundamental concern for all who make, distribute, and use its products, and for the environment in which we live. This concern is the basis for our product stewardship philosophy by which we assess the safety, health, and environmental information on our products and then take appropriate steps to protect employee and public health and our environment. The success of our product stewardship program rests with each and every individual involved with DuPont productsfrom the initial concept and research, to manufacture, use, sale, disposal, and recycle of each product.
