CSM RE4040-BLR - 4" x 40"; 1900 GPD BW-LE Brackish Water Replacement Reverse Osmosis Membrane
CSM RE4040-BLR Low Energy Brackish Water RO Membrane
4" x 40" thin film composite membrane engineered for low-pressure operation in brackish water systems. 1,900 GPD rated capacity with extended surface area to reduce energy costs while maintaining commercial-grade rejection rates.
Designed for efficiency in low-pressure brackish applications
Low Energy Operation
Optimized for lower feed pressures than standard RO membranes, reducing pump energy requirements and operational costs in brackish water systems.
Extended Membrane Area
BLR series features increased active surface area within the 4" x 40" form factor, delivering 1,900 gallons per day with higher flux rates and improved permeate output.
Thin Film Composite
TFM construction provides excellent salt rejection and chemical resistance across a wide pH range, handling brackish and tap water sources reliably.
Commercial Grade
Toray CSM engineering ensures consistent performance in demanding commercial environments, from food service to light industrial applications.
24-Month Service Life
Extended replacement interval reduces maintenance frequency and total cost of ownership when properly maintained with adequate pretreatment.
Standard 4-inch commercial housings
The CSM RE4040-BLR is a direct replacement for commercial 4" x 40" brackish water membranes. Compatible with standard 4-inch pressure vessels and commercial RO systems designed for 1,800-2,000 GPD output. Verify feed water TDS below 2,000 ppm and operating pressure between 100-225 psi for optimal performance. This membrane replaces similar models from Filmtec, Hydranautics, and other manufacturers using the 4040 format.
Replacement schedule for brackish water systems
Inspect Prefilters
Replace sediment and carbon prefilters to protect membrane from fouling. Adequate pretreatment is critical for reaching 24-month membrane life.
Performance Check
Monitor permeate TDS, flow rate, and differential pressure. Clean membrane if pressure drop increases 15% or salt rejection declines.
Replace Membrane
Replace the CSM RE4040-BLR membrane element to maintain consistent water quality and system efficiency in commercial applications.
Lower Operating Costs
Reduced pump pressure requirements translate to measurable energy savings over the membrane's service life.
Consistent Output
Toray CSM quality control ensures predictable performance across production batches for easier system design.
Proven Reliability
Industry-standard 4040 format with extended area design delivers dependable brackish water treatment in commercial settings.
