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.

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 treated

with 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 once

every two days with sufficient quality flushing water, such as pre-treated feed water, to

prevent biological growth during system shutdown. Please refer to the Toray RO Handling

Manual for suggested flushing water quality.

The presence of free chlorine and other oxidizing agents under certain conditions, such

as 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.

Permeate from the first hour of operation shall be discarded.

The customer is fully responsible for the effects of chemicals that are incompatible with the

elements. Their use will void the element Limited Warranty.

Maximum operating pressure will vary depending on feed temperature. Please ask for

detailed information from Toray if needed.

the safety or suitability of Toray's products, either
