DOW FILMTEC BW30FR-365
DOW FILMTEC™ BW30FR-365 elements have purified high biofouling feed waters since 1997. Numerous customers around the world have experienced lower operating costs by using DOW FILMTEC fouling resistant elements due to their excellent fouling resistance and cleanability. The BW30FR-365 element features:
- A wider (34 mil) feed spacer than any other industrial water purification element available today to facilitate improved cleaning.
- A proprietary modification to the FT30 memebrane chemistry providing exceptional cleanability and resistance to fouling.
- DOW FILMTEC membrane with a wide pH cleaning range (pH 1 - 13) allowing for 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 DOW FILMTEC BW30FR-365 element can be used for both potable and non-potable water applications.
A system designer can take advantage of this high productivity, high rejection, fouling resistant reverse osmosis (RO) element in any system design wher the potential of high biofouling is expected. In addition, existing installations that are experienceing high biofouling or frequent cleanings can be upgraded by retrofitting to the DOW FILMTEC BW30FR-365 element. In either case, DOW FILMTEC BW30FR-365 elements can reduce the operating costs in most biofouling cases by lowering membrane fouling, reducing average system operating pressure, and extending membrane life.
| Nominal Active Surface Area ft2 (m2) |
Permeate Flow Rate gpd (m3/d) |
Stabilized Salt Rejection (%) |
Minimum Salt Rejection (%) |
|---|---|---|---|
| 365 (34) | 9,500 (36) | 99.5 | 99.0 |
- Permeate flow rate and salt rejection based on the following test conditions: 2000 ppm NaCl, 225 psig (15.5 bar), 77°F (25°C), pH 8 and 15% recovery.
- Permeate flow rates for individual elements may vary, but will be no more than 15% below the value shown.
- Sales specifications may vary as design revisions take place.
- Active area guaranteed +/-3%. Active area as stated by Dow is not comparable to nominal membrane area often stated by some manufacturers. Measurement method described in Form No. 609-00434 (168KB PDF).
