Feed water

• The presence of free chlorine and other oxidizing agents (such as 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 contained in feed water before operating the RO system.

Product water

• Permeate from the first hour of operation shall be discarded.

Operating Information

• For recommended design ranges, consult the latest Toray technical bulletin, design guidelines, computer design program, and/or an application specialist. Failure to strictly follow the operating limits will void the Limited Warranty.
• All elements are wet tested, treated with tested feed water solution, and then vacuum packed in oxygen barrier bags with deoxidant inside.
• To prevent biological growth during system shutdown, it is recommended to perform 30-60 minutes flushing of Toray elements with seawater once every two days.
• The customer is fully responsible for the effects of chemicals that are incompatible with the elements. Their use will void the element Limited Warranty.
