Product Details
The membrane is designed for reverse osmosis systems treating water with elevated levels of organic matter, colloids, and suspended solids. Its fouling-resistant surface helps reduce contaminant deposition, supporting more stable operation and longer cleaning intervals. With a stabilized salt rejection of 99.6% and a minimum rejection rate of 99.3%, the membrane maintains consistent permeate quality during continuous operation. The optimized membrane structure also supports effective chemical cleaning, helping restore performance after fouling and reduce overall maintenance requirements in commercial and industrial water treatment systems.

* Active membrane area may vary within ±4%.
* Salt rejection performance typically stabilizes after 24–48 hours of continuous operation.
Membrane Performance
Water sources with high fouling potential often cause rapid performance decline in conventional RO membranes. This membrane is designed to operate more effectively in applications where organic matter, colloids, or suspended solids are present after pretreatment.
The membrane delivers 99.3% stabilized salt rejection and 2250 GPD (8.7 m³/d) permeate flow under standard test conditions while supporting stable operation and cleaning recovery.
Actual operating results may vary depending on water quality, pretreatment effectiveness, system design, and operating conditions.





Typical Water Sources
This membrane is commonly applied in systems treating:
* Surface water
* River water
* Lake water
* Reclaimed water
* Secondary treated wastewater
* Municipal water with high organic content
* Industrial process water
* Groundwater with elevated fouling potential
FAQ
Q1. How is this membrane different from a standard RO membrane?
A:The membrane features a fouling-resistant surface designed to reduce contaminant attachment and improve cleaning recovery compared with conventional RO membranes.
Q2. How is this membrane different from a standard RO membrane?
A:The membrane surface features hydrophilic and low‑charge modification, which significantly reduces contaminant adhesion. Its smooth flow channel design also makes foulants easier to dislodge during cleaning, resulting in about 15–20% higher cleaning recovery compared to conventional membranes.
Q3. Can the membrane be chemically cleaned?
A:Yes. The membrane supports chemical cleaning within a pH range of 1–13.
