Suro BW-4040 Commercial RO Membrane is a high-performance brackish water reverse osmosis membrane designed to deliver reliable, efficient, and long-lasting water purification for a wide range of industrial and commercial applications. Engineered with advanced thin-film composite (TFC) membrane technology, this 4″ x 40″ membrane element is capable of producing up to 2400 gallons per day (GPD) while maintaining a high salt rejection rate of up to 99.7%.

Whether you need purified water for industrial processes, commercial facilities, agriculture, food and beverage industries, or municipal water treatment, the Suro BW-4040 ensures stable and consistent performance even under challenging water conditions.

✅ Key Features & Benefits

1. Superior Salt Rejection (99.7%)
   The Suro BW-4040 membrane effectively removes dissolved salts, heavy metals, chemicals, and organic impurities, ensuring clean and safe water output. This high rejection capability makes it ideal for treating brackish water with TDS levels between 2000 – 8000 ppm.

2. High Water Output
   Designed for demanding environments, this commercial-grade RO membrane provides a nominal permeate flow at optimal conditions. It guarantees fast and efficient water production, reducing downtime and ensuring a continuous supply of purified water.

3. Durable Thin-Film Composite (TFC) Design
   Built with polyamide composite layers, the Suro BW-4040 membrane resists fouling, scaling, and chlorine damage better than conventional membranes. This increases its operational lifespan and minimizes the frequency of replacements.

4. Versatile Applications
   The Suro BW-4040 is widely used across different industries, including:

   • Industrial water treatment for factories and manufacturing units.

   • Commercial RO systems in hotels, offices, and water refilling stations.

   • Agricultural irrigation systems requiring high-quality purified water.

   • Food and beverage production for ensuring clean, safe, and contaminant-free water.

   • Municipal water purification to meet safe drinking water standards.

5. Energy-Efficient & Cost-Effective
   With its high recovery rate and low operating pressure, the BW-4040 reduces energy consumption while maintaining superior performance. Its long service life lowers the total cost of ownership, making it a smart investment for businesses.
