Operating Limits

Membrane Type Poly-amide Thin-Film Composite
Maximum Operating Temperature 113° F (45°C)
Maximum Operating Pressure 150 psig (10 bar)
Maximum Feed Flow Rate 2.0 gpm (7.6 lpm)
pH Range, Continuous Operations 2–11
Maximum Feed Silt Density Index (SDI) 5
Free Chlorine Tolerance < 0.1 ppm

a. Maximum temperature for continuous operation above pH 10 is 95oF (35oC).

b. Under certain conditions, the presence of free chlorine and other oxidizing agents will cause premature membrane failure. Since oxidation damage is not covered under warranty, Dow recommends removing residual free chlorine by pre-treatment prior to membrane exposure. Please refer to technical bulletin 609-22010 for more information.

Important Information:

  • It is recommended that systems using these elements rinse the elements for 24 hours, prior to first use, to meet NSF/ANSI 58 Standard.
  • The first full tank of permeate must be discarded. Do not use this initial permeate for drinking water or food preparation.
  • Keep elements moist at all times after initial wetting.
  • To prevent biological growth during prolonged system shutdowns, it is recommended that membrane elements be immersed in a preservative solution. Rinse out the preservative before use.
  • The membrane shows some resistance to short-term attack by chlorine (hypocrite). Continuous exposure, however, may damage the membrane and should be avoided.
  • DOW FILMTEC™ Home Drinking Water Reverse Osmosis Elements may be covered under the DOW FILMTEC™ Reverse Osmosis and Nano filtration Element Three-Year Prorated Limited Warranty, 609-35010-1006 extended to O Ems. Such Limited Warranty is non- transferable. Contact a Dow representative for more information.

If operating limits and guidelines given in this Product Information Bulletin are not strictly followed, the Limited Warranty will be null and void. The O EM is fully responsible for the effects of incompatible chemicals and lubricants on elements. Use of any such chemicals or lubricants will void the Limited Warranty.
