FilmTec™ Seamaxx™–440i Elements are the choice for seawater systems operating at low to medium levels of salinity and temperature, as well as for brackish water with relatively high salinity. The element’s flowrate is significantly above flowrates of any other SWRO element currently available in the market. This extraordinary high element productivity leads to substantial savings, primarily in energy consumption when compared to conventional low-energy SWRO products. In addition, FilmTec™ Seamaxx™–440i includes the typical FilmTec™ Element features:

• The 28-mil feed spacer combines low differential pressure with low cleaning frequency and high cleaning efficiency.
• The renowned iLEC™ Interlocking Endcaps help to reduce system operating costs and the risk of O-ring leaks.
• The oxidative-free membrane manufacturing process results in high membrane robustness and long-term stable performance.
• The widest pH range for cleanings (pH 1 – 13) allows effective cleanings even in cases of severe fouling.
• The automated, precision fabrication gives a greater number of shorter membrane leaves thus reducing fouling while maximizing element efficiency.

Key Features:

• Delivers very high permeate flow allowing considerable savings in energy consumption.
• Permits low system capital cost by maximizing production capacity.
• Excellent durability resulting in stable, long-term performance.
• Includes iLEC™ interlocking end caps, reducing system operating costs and the risk of o-ring leaks that can cause poor water quality.

Key Applications:

• Seawater desalination for municipal and industrial applications.
• Suitable for low and medium feed water salinity.
• Ideal for installations with high energy cost.
• Applicable for optimized Internally Staged Designs (ISD) in combination with other FilmTec™ seawater membranes.

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.
• Wear protective eye shields, gloves, and sleeves to avoid prolonged contact with eyes, skin, and clothing.
