High-temperature RO
Thermal resilience.
With the test context intact.
Evaluate the published temperature study separately from high-pressure brine-concentration results.
PUBLISHED RESEARCH · SCIENCE ADVANCES
A controlled heating-and-cooling study.
Wu et al. (2026) tested membranes at 60 bar with a 32,000-ppm NaCl feed while cycling temperature from 20 to 80 °C and back. TFX maintained approximately 99% salt rejection; the tested conventional TFC membranes fell below 90% and did not fully recover after cooling. (Wu et al., 2026)
The study associated conventional-membrane failure with thermoplastic-support deformation and selective-layer damage. The thermoset architecture resisted those changes in the reported experiments.
APPLICATION EVALUATION
Define the temperature duty precisely.
- 01
Operating sequence
Specify normal, peak, start-up, shutdown, and cleaning temperatures, with durations.
- 02
Simultaneous conditions
State the pressure, feed chemistry, and recovery occurring at each temperature.
- 03
Assembly qualification
Evaluate the membrane, adhesives, seals, spacers, pressure vessel, and other wetted components together.
WHAT TO REQUEST
A temperature-specific evaluation package.
Share the feed composition, temperature profile, pressure, flow, required water quality, and cleaning requirements. The objective is to assess a defined elevated-temperature duty rather than extrapolate from a single maximum.

Discuss an elevated-temperature application.
Share the feed, flow rate, temperature, recovery target, and product-water requirement. We will help scope an application-specific evaluation.
