Ingenious Membranes, a company incorporated in San Sebastián in 2018 that trades as Surphase, makes a sensor that detects fouling, the build-up of deposits on reverse osmosis membranes, directly on the membrane surface in real time and without interrupting the process. Its EIC Accelerator project, Excalibur, "Unlocking operational excellence in water desalination plants by nanoscale fouling sensor technology", receives an EU contribution of €2,481,137 and runs from January 2025 to December 2026, according to CORDIS. The patented system, granted in the EU, is designed to be three orders of magnitude more sensitive than existing technologies and to let operators clean membranes predictively rather than after problems appear.
After the first year, the report says, "the first milestones of EXCALIBUR were fully achieved": the sensor was designed to withstand harsh desalination conditions, data processing was professionalised with industry-standard cybersecurity, and an operator interface was built, according to CORDIS. The system "is being tested and then ready for deployment in a relevant industrial environment". The company projects installing its solution in more than 666 desalination plants by 2030. No installation at a named plant has been announced.

Where Surphase Stands Now
The Spanish register lists sales in the €500,000 to €1 million bracket for its latest filed year and joint administrators, according to Empresia. Surphase's website advertises its early fouling detection for desalination plants but does not name customers or pilot sites. No equity round or EIC Fund investment has been announced.
"Currently, there exist only corrective measures which are entirely insufficient as they are based on indirect measurements."
Surphase, EIC project reportThe Technology: Seeing Fouling Before It Hurts
Membrane desalination is growing fast, with more than 22,000 plants operating in 2022, the EIC report says, but fouling raises energy use and forces frequent, sometimes aggressive, chemical cleaning that shortens membrane life. Existing measures are corrective and rely on indirect measurements, the report says. Surphase's sensor measures the membrane surface itself, detecting the first nanoscale layers and the effect of cleaning, and its software turns that into operating advice.
What the EIC Award Promised, and What the Record Shows
The project runs to December 2026, so it is too early to judge it. Design milestones are met. The step that matters to plant operators, a sensor running in a working desalination plant and showing the claimed savings, has not been documented publicly.

The Money
The award was blended finance; no EIC Fund investment has been announced. The company's financing beyond the EIC grant is not public.
What Cannot Be Checked
Questions for the EIC
Where the Excalibur sensor is being tested, whether any desalination operator has bought it, whether the EIC Fund invested, and what savings have been measured are not public.
Why Europe Should Care
Water stress affects 40% of the world's population, the EIC report says, and membrane desalination is growing fast. Lower energy and chemical use per cubic metre would cut both cost and environmental impact. The benefits depend on the sensor proving itself in real plants.
What the award promised
Real-time nanoscale fouling monitoring deployed in desalination plants.
What the record shows
Sensor and software completed; plant deployment not yet reported.
The Verdict
Ready for the plant floor
Surphase has built its sensor. It now has to show it saves money in a working desalination plant.
