Operating information

• For detailed design ranges, consult Toray's technical bulletin, design guidelines, computer design program, or an application specialist. Failure to follow operating limits may 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, flushing with seawater for 30-60 minutes every two days is recommended.
• The presence of free chlorine and other oxidizing agents, especially with heavy metals acting as oxidation catalysts, can cause unexpected membrane oxidation. It is strongly recommended to remove these oxidizing agents from feed water before RO system operation.
• 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 Limited Warranty.

Notice

• All data may change without prior notice due to technical modifications or production changes.
