At Purecowater, we supply high-quality filtration solutions like the CSM RE8040-BE to ensure your systems run at peak performance. Whether you are treating well water, surface water, or wastewater, understanding the specifications and capabilities of this membrane is essential for optimizing your operation.
What is the CSM RE8040-BE?
The CSM RE8040-BE is a spiral-wound Thin-Film Composite (TFC) membrane element. It belongs to the “Brackish Water” (BW) family of membranes, which are specifically optimized to treat water with moderate to high dissolved solids (TDS) while operating at standard pressures.
The “BE” designation typically indicates a high-rejection standard model. This means it prioritizes the removal of contaminants—such as salts, heavy metals, and organic compounds—over ultra-low energy consumption, making it ideal for applications where water purity is the critical metric.
Key Features
- High Salt Rejection: Achieves nominally 99.7% rejection, ensuring superior filtrate quality.
- Durability: Constructed with cross-linked polyamide, offering robust chemical resistance during cleaning (CIP).
- Standard Fit: Designed as a standard 8.0″ x 40″ element, fitting into nominal 8-inch pressure vessels used globally.
- Versatility: Effective on feed water concentrations up to 10,000 ppm TDS.

Why Choose CSM Industrial Membranes?
CSM membranes are renowned for their balance of performance and value. The RE8040-BE series specifically offers a robust barrier against salts and organics without requiring the extreme operating pressures of seawater membranes. This results in an economical operation with reduced energy costs compared to higher-pressure alternatives, all while maintaining excellent permeate quality.
