Product Details
High temp RO for power plant applications requires membrane elements capable of maintaining stable salt rejection and permeate production under elevated temperatures and demanding operating conditions. The RST8040-HS1 is a high temperature RO membrane developed for boiler feed water treatment, power plant make-up water purification, and other industrial systems where conventional membranes may face thermal limitations.
As a hot water sanitizable RO membrane, this element supports high-temperature operation up to 55°C and thermal sanitization at 85°C, helping reduce biofouling risks while maintaining membrane integrity. With a nominal salt rejection of 99.7% and 8,800 GPD permeate flow, it is suitable for high-purity water production in power generation environments.

Why Use High Temp RO Membrane for Power Plant Water Treatment?
Selecting the right high temp RO for power plant operation is not only about permeate output or salt rejection. In thermal power systems, membrane elements are often exposed to elevated feed temperatures, sanitization procedures, fluctuating water quality, and continuous-duty operating cycles that place additional stress on conventional RO elements.
A hot water sanitizable RO membrane addresses several challenges commonly found in power plant water treatment.
A. Enhanced Thermal Stability for Warm Feed Streams
Conventional RO elements often experience accelerated material aging and decreased rejection when exposed to warm process water. Our high-temperature RO membrane is specifically formulated with a reinforced polyamide layer that maintains its pore structure and flux consistency even at 55°C, ensuring the stability of your water treatment train.
B. Biofouling Control via Thermal Sanitization
Biological growth in power plant RO systems can lead to increased differential pressure and reduced system efficiency. By utilizing a hot water–sanitizable RO membrane, plant operators can implement 85°C thermal disinfection protocols. This physical sanitation method penetrates biofilms more effectively than chemicals alone, extending the intervals between intensive chemical cleanings.
C. Superior Protection for Downstream Boilers
For boiler feed water RO membrane applications, consistent dissolved solids removal is non-negotiable. With a nominal rejection of 99.7%, the RST8040-HS1 reduces the ionic load on downstream ion-exchange (IX) or electrodeionization (EDI) units, preventing scaling in high-pressure steam generators and turbines.
D. Continuous-Duty Reliability
Power plants demand 24/7 reliability. Our dedicated power plant reverse osmosis membrane is designed for the rigorous duty cycles of the energy sector, supporting a wide operating pH range and high-pressure tolerance to handle fluctuating raw water chemistries.
FAQ
1. Is it suitable for boiler feed water treatment systems?
Yes. The element is commonly applied in boiler feed water RO membrane systems where consistent dissolved solids removal is required to protect downstream boilers and polishing units.
This membrane is designed with a thermally stable spiral-wound structure that allows controlled hot water sanitization up to 85°C. It maintains rejection performance after repeated thermal cycles when operated within specified pressure and differential limits.
2. What is the salt rejection performance under standard conditions?
Under test conditions (1500 mg/L NaCl, 225 psi, 25°C), the membrane provides:
Nominal rejection: 99.7%
Minimum rejection: 99.4%
3. What type of feed water is recommended?
The membrane is designed for pretreated industrial water with feed pH between 2–10 and low free chlorine levels (<0.1 mg/L). It is typically used after standard pretreatment in power plant systems.
4. What is the maximum operating pressure?
The maximum operating pressure is 600 psi (4.14 MPa), which supports high-pressure industrial desalination applications.
5. What is the recommended temperature before full thermal operation?
The pre-heat stabilization limit is ≤45°C to ensure controlled transition into higher temperature operating conditions.
