Industrial RO Membranes
Brackish Water Series
High-rejection spiral-wound RO elements for industrial process water, boiler feed, municipal treatment, and Zero Liquid Discharge applications. Available in 4-inch and 8-inch formats.
Engineered for Industrial Reliability
TL Environment's Industrial RO Membrane series is built on a polyamide thin-film composite (TFC) structure, delivering consistent high rejection performance across a broad range of feed water chemistries. The series covers standard brackish water applications (BWRO), fouling-resistant variants for high-SDI feeds, and high-recovery elements optimized for ZLD pre-treatment systems.
All elements are manufactured to ISO 9001 quality standards with 100% pressure testing before shipment. Each batch is accompanied by a factory test report documenting actual permeate flow and salt rejection values — not nominal specifications.
The 8-inch (8040) format is the industry standard for large-scale industrial systems and is compatible with all major pressure vessel manufacturers. Custom configurations including 4-inch elements for pilot systems and skid-mounted packages are available on request.

Designed for Industrial Demands
High Salt Rejection
Nominal NaCl rejection ≥99.5% under standard test conditions (2,000 ppm NaCl, 1.55 MPa, 25°C, pH 7.5, 15% recovery).
Wide pH Tolerance
Operating pH range 2–11; cleaning pH range 1–13. Suitable for aggressive industrial feed water chemistries.
Chlorine Resistance
Polyamide thin-film composite membrane with enhanced oxidant tolerance. Compatible with standard CIP protocols.
Consistent Performance
Tight manufacturing tolerances ensure element-to-element consistency across large project orders. Batch testing available.
Standard 8-Inch Format
Industry-standard 8-inch diameter elements are compatible with all major pressure vessel brands including Codeline, Pentair, and Protec.
Export-Ready Packaging
Each element is individually vacuum-sealed, pressure-tested, and packaged for international shipping. Shelf life: 12 months sealed.
