We have industrialized a natural process.

At Aquastill we have industrialized a natural process and made membrane distillation (MD) applicable. On a medium scale (1000 m3/day), but on a smaller scale (10 m3/day) as well. In contrast to other thermal technologies, membrane distillation can be highly efficient on a smaller to medium scale, making it a very interesting solution when large scale implementation is not desirable nor possible.

Applicable and complementary.

Aquastill has made membrane distillation applicable and scalable, but complementary as well. As a hybrid system with other membrane water treatment systems such as reverse osmosis (RO), ultrafiltration (UF), nanofiltration (NF), microfiltration (MF) and forward osmosis (FO). It is also with renewable energy technologies like solar, photovoltaic, salt gradient solar and geothermal systems. So if you want to use renewable heat and regenerate saline water, you go to Aquastill.

Aquastill’s technology can operate at a very wide range of salinity, making MD suitable to treat feeds that vary from pure seawater to several forms of industrial waste water, while achieving the main needs of our customers. Either your goal is to greatly increase the volume of clean water produced without comparably raising your energy costs (to get the maximum clean water yield of your feed with very small amount of brine to discharge) or to make greater use of your waste water by reusing most of it, Aquastill is ready to help with these challenges.


Desalination of sea water powered by genset waste heat.

Produce more potable water with less energy

The average water consumption per tourist in remote touristic locations such as Barbados, Cyprus and Malta can reach 2,000 L per day, which can represent up to 7.3% of the national water consumption…

Desalination of sea water powered by solar heat.

Produce more potable water with less brine

In small rural/residential communities in remote sunny locations not connected to the water and/or electricity grid, sources of clean water are becoming scarce as these communities are in dire need of…

Desalination of industrial waste water powered by waste heat.

Reuse more water with less brine

In industry in general, fresh water is a fundamental resource for innumerous applications. For example: the oil and gas industry, which uses a great portion of its fresh water intake to inject into the reservoir to counteract the subsoil pressure and achieve high recovery levels…
