Product Overview: CSM RE4040-BE
The CSM RE4040-BE is a high-performance brackish water reverse osmosis (RO) membrane element designed for industrial and commercial water treatment applications. Known for its durability and energy efficiency, this 4-inch by 40-inch membrane is an industry staple for systems requiring reliable salt rejection and consistent permeate flow.
As a leading choice for filtration professionals, the CSM RE4040-BE utilizes Thin-Film Composite (TFC) polyamide technology to deliver high productivity while maintaining excellent chemical stability. This makes it an ideal solution for treating tap water, brackish well water, and surface water in various manufacturing and municipal settings.
Key Features & Benefits
- High Rejection Rates: Delivers superior salt rejection performance, ensuring high-purity permeate suitable for critical industrial processes.
- Energy Efficiency: Designed to operate effectively at lower pressures (approx. 225 PSI standard, adaptable to low pressure applications), reducing energy consumption and operational costs.
- Chemical Durability: The TFC material allows for a wide pH cleaning range, making the element resistant to fouling and easier to clean (CIP).
- Universal Fit: Standard 4″ x 40″ dimensions ensure compatibility with most standard commercial stainless steel or fiberglass membrane housings.
