Operating Limits
1. For the recommended design range, please consult the latest Toray technical bulletin, design guide
lines, computer design program, and/ or call an application specialist. If the operating limits given in this
Product Information Bulletin are not strictly followed, the Limited Warranty will be null and void.
2. All elements are wet tested, treated with a 1% by weight percent sodium bisulfite storage solution, and
then vacuum packed in oxygen barrier bags, or treated with tested feed water solution, and then
vacuum packed in oxygen barrier bags with deoxidant inside. To prevent biological growth during short
term storage, shipment, or system shutdown, it is recommended that Toray elements be immersed in a
protective solution containing 500 – 1,000 ppm of sodium bisulfite (food grade) dissolved in permeate.
3. The presence of free chlorine and other oxidizing agents under certain conditions, such as heavy
metals which acts as oxidation catalyst in the feed water will cause unexpected oxidation of the
membrane. It is strongly recommended to remove these oxidizing agents contained in feed water
before operating RO system.
4. Permeate from the first hour of operation shall be discarded.
5. The customer is fully responsible for the effects of chemicals that are incompatible with the elements.
Their use will void the element Limited Warranty.
1. 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.
2. All data may change without prior notice, due to technical modifications or production changes.
