X-20 ^TM thin film composite membrane

X-20 TM is a proven low flow membrane, which features the unique poliamide-ures chemistry possessing a uniform composition throughout the membrane. The surface charge of the X-20 membrane minimizes fouling of organic elements and maximizes silica rejection, resulting in dramatically lower operating costs.

Advance chemistry
The Trisep X-20 TM is provided with amino surface functional group, neutral surface charge, fully aromatic polyamide-urea backbone, and a surface chemistry integral to polymer.

Benefits

• Decreased regeneration costs (up to 500%)
• Decreased cleaning costs (up to 600%)
• Increased membrane life (up to 3 times)
• Decreased system downtime (up to 3 times)
• Lower system maintenance costs (up to 3 times)
• Increased flux rates (up to 20%)
• Stable flux performance
• Superior rejection of pesticides
• Better cleaning results

Performance
Trisep X-20 TM offers a silica reduction up to 99.8%, a continuous chloramines tolerance up to 5 ppm, a high scaling and biological fouling resistance and stable performance over a broader pH range.

Field experience
Trisep has over 7 years of proven field experience with over 10.000 units sold worldwide.
Trisep membranes were successfully applied at:

• Shell Oil Corp.
• Lone Star power
• Jones Station
• Sony Corp.
• Copesul (Brazil)
• Envig (South Africa)
• Nevada CoGen Association
• Esmil (Europe)
• WaterSolve
• Duke power, Alan Station
• Allied Signal
• National Semiconductor
• Purac, ND
• Madras Refineries Ltd.

In all these application it proved an high biofouling reduction, an increase in silica rejection, slowing the membrane degeneration and increasing their life-time. This allowed to highly reduce operating costs.

Cost-Benefit analysis
A competitive comparison based on actual field experience in various applications shows that using X-20 membranes in an RO systems of 100 GPM with 2.000 TDS and 10 ppm of silica decreases the annual operating costs by 33%.
A cost-benefit analysis carried out for Hyundai Corp. in Korea shows that:

• X-20 decreases cleaning time by over 7 times
• X-20 saves annual cleaning chemical costs by 3.7 times
• X-20 allows 66% savings on element replacement costs
