Mechanical / Hydraulic

• Dimensions are shown in Inches (millimeter). The nominal length is 40 inches (1,016 mm) and the nominal diameter is 7.9 inches (201 mm) for the active membrane area. See the official PDF for exact tabulated values or diagrams detailing specific dimensions, including end-caps and permeate tube.

Operating Information

• For recommended design ranges, consult the latest Toray technical bulletin, design guidelines, computer design program, or an application specialist.
• Failure to strictly follow operating limits given in this Product Information Bulletin will void the Limited Warranty.
• All elements are wet tested, treated with tested feed water solution, and vacuum packed in oxygen barrier bags with deoxidant.
• To prevent biological growth during system shutdown, it is recommended to flush Toray elements with seawater for 30-60 minutes once every two days.
• The presence of free chlorine and other oxidizing agents (especially in combination with heavy metals acting as oxidation catalysts) in the feed water can cause unexpected oxidation of the membrane. It is strongly recommended to remove these oxidizing agents before operating the RO system.
• Permeate from the first hour of operation shall be discarded.
• Customers are fully responsible for the effects of chemicals incompatible with the elements; their use will void the element Limited Warranty.

Notice

• Toray accepts no responsibility for results obtained by the application of this information or the safety or suitability of Toray's products, either alone or in combination with other products. Users are advised to make their own tests to determine the safety and suitability of each product combination for their own purposes.
