Dow Performance Features:
The DOW FILMTECTM BW30-400 membrane element has a nominal effective membrane area of 400 square feet and a water production capacity of 40 m3/d (10,500 gpd) under standard test conditions. Its outer diameter is the same as that of other standard 8 inch elements. BW30-400 increases the amount of water produced by increasing the membrane area, not by increasing the membrane flux and the pressure of the feed water. Therefore, the rate of fouling can be maintained at a low level, thereby maintaining long-term high-yield water and prolonging the life of membrane elements. The low operating pressure of this component increases the economical efficiency of the system. The increased film area of the BW30-400 allows the newly designed RO system to use fewer components, thus making the system more compact and saving installation costs.

1. The above test values are based on the following test conditions: 2,000 ppm NaCl, 225 psi (15.5 bar), 77°F (25°C), pH 8, 15% recovery.
2. The flow of single components may be different, but will not fall below the listed value by more than 15%.
3. Product specifications may change slightly as product quality increases.
4. The effective membrane area will be within plus or minus 5% of the value given. Filmtec's method of calculating the effective membrane area is different from that of other manufacturers. Please refer to the literature numbered 609-00434 for details.

1. The typical recovery rate is for a single component and the recovery rate is the percentage of the product water flow divided by the feedwater flow rate. 1 inch = 25.4 mm
2. When designing a multi-component system, refer to the Dow Water Design Division's design guidelines and follow the appropriate recovery rate limits based on the type of water supply.
3. The element is fitted with a pressure vessel with a nominal internal diameter of 8.00-in. (203 mm).
