Description:  
The DuPont™ FILMTEC™ BW30XHR PRO 400/34 is an extra high rejection reverse osmosis element engineered for superior salt rejection and long-lasting performance in brackish water applications. With an average NaCl rejection of 99.8% and a large active area of 400 ft², this element maximizes permeate flow and system efficiency. The 34 mil LDP feed spacer enhances fouling resistance and lowers cleaning frequency, making it ideal for challenging water conditions with high scaling or biofouling potential.

Key Features:

• Exceptional salt rejection for demanding water quality goals

• High productivity with large membrane area and optimized flow

• Enhanced spacer design minimizes fouling and pressure drop

• Reliable DuPont quality for long membrane life and performance stability

Application:

• Ideal for municipal and industrial brackish water treatment

• Suitable for high-salinity water sources where top rejection performance is needed

• Used in reverse osmosis plants, water reuse, and ultrapure water production
