Dow Filmtec BW30-365-FR 40 inch x 8 inch Fouling Resistant Mambrane

Filmtec BW30-365-FR elements have purified high biofouling feed waters since 1997. Customers have experienced lower operating costs by using Filmtec fouling resistant elements due to their superior fouling resistance and cleanability.

A system designer can take advantage of this high productivity, high rejection, fouling resistant reverse osmosis (RO) element in any system design where the potential of high biofouling is expected. In addition, existing installations that are experiencing high biofouling or frequent cleanings can be upgraded by retrofitting to the Filmtec BW30-365-FR element. In either case Filmtec BW30-365-FR elements can reduce the operating costs in most biofouling cases by lowering membrane fouling, reducing average system operating pressure, and extending membrane life.

Features:

  • A wider (34 mil) feed spacer than any other industrial water purification element to facilitate improved cleaning.
  • A proprietary modification to the FT30 membrane chemistry providing superior cleanability and resistance to fouling. Filmtec membrane with the widest pH cleaning range in the industry (pH 1-13) allowing for the most effective cleaning of scaling, organic compounds and biofilm.
  • More but shorter membrane leaves resulting in a more efficient membrane element design reducing the overall effect of fouling.
  • The Filmtec BW30-365-FR element can be used for both potable and non-potable water applications.

Specifications:

  • Membrane Type: Polyamide Thin-Film Composite (TFC)
  • Maximum Operating Temperature: 113?F (45?C)
  • Maximum Operating Pressure: 600 psi (41 bar)
  • Maximum Pressure Drop: 15 psi(1.0 bar)
  • Maximum Feed Flow Rate: 70 gpm (16 m3/hr)
  • pH Range, Continuous Operation: 2-11***
  • pH Range, Short-Term Cleaning (30 min.): 1-13* (30min)
  • Maximum Feed Silt Density Index: 5 SDI
  • Free Chlorine Tolerancec: <0.1 ppm**
  • Permeate flow rate gpd (m3/d): 9,500 GPD (36 m3/day)*
  • Stabilized salt rejection (%): 99.5

*Permeate flow and salt rejection based on the following standard conditions: 2,000 ppm NaCl, 225 psi (15.3 bar), 77°F (25°C), pH 8 and 15% recovery. Flow rates for individual elements may vary but will be no more than 7% below the value shown.

**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 pretreatment prior to membrane exposure. Most RO systems have carbon pre-filters for this purpose.

***Maximum temperature for continuous operation above pH 10 is 95F (35C).

Note: Active surface area guaranteed +/-3%. Active area as stated by Filmtec is not comparable to nominal membrane area often stated by some manufacturers.
