*The limitations shown here are for general use.  For specific projects, operating at more conservative valuesmay ensure the best performance and longest life of the membrane.  See Hydranautics Technical Bulletins formore detail on operation limits, cleaning pH, and cleaning temperatures.
Test condition:
The stated performance is initial (data taken after 30 minutes of operation), based on the following conditions:

  • 1500 PPM NaCl solution
  • 150 psi (1.05 MPa) Applied Pressure
  • 77  ℉ (25  ℃) Operating Temperature
  • 15% Permeate Recovery
  • 6.5 – 7.0 pH Range

(Data taken after 30 minutes of operation)

5. Operating information:

  1. For the recommended design range, please consult the latest Hydranautics 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
