Summary
Product Identification
The TriSep X-20™ is a new generation, highly durable reverse osmosis (RO) membrane specifically designed for high-fouling feedwater applications. It features a new and unique membrane chemistry based on a polyamide-urea copolymer barrier layer, contrasting with traditional polyamide polymers.
- Product Codes:
- 4040-X201-TSF
- 8040-X201-TSA
- Membrane Type: X-20™ Polyamide-urea Thin Film Composite
- Configuration: Spiral Wound, Fiberglass Outer Wrap
Features and Benefits
The X-20™ membrane incorporates FoulGard Technology, offering significant advantages:
- Low Fouling characteristics
- Easy to Clean
- Improved Silica Rejection
- Resists up to 3 ppm of chloramine
- Proven performance, designed for high-fouling feedwaters.
The unique surface chemistry of the X-20 membrane, with residual amino groups, provides improved performance compared to traditional polyamide membranes which have residual carboxylic acid groups. Case studies indicate reduced DI regeneration rates and improved system silica rejection over extended periods compared to other membranes.
Operating Limits
- Recommended Operating Pressure: 100 - 300 psi (0.7 - 2.1 MPa)
- Maximum Applied Pressure: 600 psi (4.1 MPa)
- Feedwater pH Range: 4 - 11 Continuous
- Chlorine Tolerance: <0.1 ppm
- Chloramine Tolerance: Up to 3 ppm continuous
- Minimum Brine/Permeate Flow Ratio: 5:1
- Maximum SDI (15 minutes): 5.0
- Maximum Turbidity: 2 NTU
