Sustainable Thermal Desalination
Membrane distillation
by Aquastill.
Aquastill is the global technology leader in the field of membrane distillation. Our innovative technology can desalinate water on a medium (1000 m3/day) scale, at competitive costs and with minimal impact on the environment. Using waste or solar heat to power the process sustainably. With Aquastill you can desalinate water while reducing your carbon footprint.
Aquastill will stop all its activities
Aquastill will stop all its activities as from 1st of July 2026.
Aquastill has decided to discontinue her operations due to a lack of future perspective.
Sole shareholder INVERTR Investments has funded 15 years the development of the Aquastill Membrane Distillation (MD) Technology.
This has resulted in a patented working solution (PLICA-modules & PURA-systems), multiple successful pilot projects, a demo project in Bonaire, multiple innovation awards and a solid reputation in the scientific world.
A wide range of possible applications have been explored, using waste heat as the sustainable energy source, such as:
- Off-grid desalination of sea water
- Ultra-pure water for electrolyzing hydrogen
- Desalination of industrial waste water (incl. metal pickling)
However, despite all the investments, Aquastill has not been able to validate a commercially viable market, nor finding an industrial partner interested to scale-up the Aquastill technology.
The discontinuation implies that as from now onwards Aquastill will no longer enter into new obligations, while existing obligations will be fulfilled in an organized manner within the next months.
Aquastill is highly grateful for the support over the years from the investor, employees, clients, suppliers and the academic world.
Why
membrane distillation?
The world has a great need for clean water and, on the other hand, has excessive waste heat and solar heat sources. Aquastill membrane distillation uses these heat sources to extract pure water from saline water. Aiming to produce safe drinking or purified water.
Who benefits from
membrane distillation?
Anyone who needs clean water and has access to sea water or brackish water, can benefit from our technology. Also if you need to dispose saline waste water and want a Zero Liquid Discharge (ZLD) solution, membrane distillation can be of help.
What is
membrane distillation?
At Aquastill we have industrialized a natural process. Our technology uses membrane distillation to extract pure water from a saline stream by evaporation through a hydrophobic membrane. Rejecting 99,97% contaminant in a single step.
How does our
membrane distillation
work?
Aquastill has closely collaborated with the most renowned research institutes, universities and multinationals on earth. Over forty successful installations all over the world show capacities for clean water generation that are out of this world. Want more proof?
