Operating Information

1.  Please consult the latest Toray technical bulletin, design guidelines, computer design program, or call an application specialist for the recommended design range. Not strictly following the operating limits stated in this bulletin will void and nullify the Limited Warranty

2.  All RO elements are wet tested treated with a 1 percent by weight sodium bisulfite storage solution. Afterward, the RO elements are vacuum packed in oxygen barrier bags or treatedwith a tested feed water solution, and then vacuum sealed in oxygen barrier bags with deoxidant inside. Toray recommends flushing Toray RO elements for 30 to 60 minutes onceevery two days with sufficient quality flushing water, such as pre-treated feed water, toprevent biological growth during system shutdown. Please refer to the Toray RO Handling Manual for suggested flushing water quality.

3.  The presence of free chlorine and other oxidizing agents under certain conditions, suchas heavy metals that act as oxidation catalysts in the feed water, will cause unexpected oxidation of the membrane. Toray strongly recommends removing these oxidizing agents contained in feed water before operating the 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 theelements. Their use will void the element Limited Warranty.

6.  Maximum operating pressure will vary depending on feed temperature. Please ask for detailed information from Toray if needed.
