Applied pressure
Maximum pressure reported in the cited membrane study.
Performance
Evidence with the conditions attached.
Published membrane results provide the scientific basis for TFX. Element ratings, service life, and plant economics require separate qualification.
PRESSURE STUDY · WU ET AL., 2025
High-pressure membrane-coupon evidence.
NaCl feed concentration
High-salinity testing reported with greater than 99% rejection.
Water-permeance retention
Tailored TFX at 200 bar relative to its 60 bar reference.
The company brochure reports these results from Wu et al. (2025). Permeance retention is a pressure-comparison metric, not “structural integrity” and not a lifetime compaction warranty. (Wu et al., 2025)
Laboratory membrane-coupon results are not commercial element ratings. Pressure, salinity, and temperature results must be read with their individual test conditions; separate maxima do not define a combined operating envelope.
SEPARATE TEMPERATURE STUDY · WU ET AL., 2026
Thermal testing must retain its own context.
The temperature investigation is presented separately from the pressure-salinity results. Its conditions and findings are summarized on the high-temperature application page. (Wu et al., 2026)

Compare like-for-like.
| Reported quantity | What it describes | What it does not establish |
|---|---|---|
| Water permeance | Water transport normalized by the relevant driving force. | A universal element flow at all feeds and recoveries. |
| Salt rejection | The observed separation under the stated feed and test conditions. | All-ion selectivity, mineral recovery yield, or guaranteed product quality. |
| Pressure and temperature tests | The conditions used in a particular investigation. | A combined continuous-duty element rating. |
| Permeance retention | A defined comparison to a specified reference state. | A lifetime or 1,000-hour durability guarantee. |
| Application-development values | Brochure-listed product reference values. | A released commercial datasheet or warranty. |
The distinctions above are technical interpretation guidance. Use the underlying papers and the current application-specific data package for detailed evaluation.
APPLICATION QUALIFICATION
Agree on the acceptance criteria first.
- 01
Feed and duty
Record composition, temperature, flow, recovery, and required product quality.
- 02
Element evaluation
Measure separation, normalized performance, pressure losses, and stability in the selected configuration.
- 03
Field qualification
Use representative feed and operating sequences to assess the intended duty, rather than extrapolating from a coupon maximum.
