Although 70% of the world is covered in water, only 2.5% is fresh water, the rest is salt and ocean water. In fact, freshwater represents a very small portion of all waters and, furthermore, the fraction of freshwater available is even smaller than the reported percentage.
In this challenging reality, of scarcity of drinking water, some countries (through organizations and Research Institutes) stand out in the development of technologies for seawater desalination, among them it is possible to highlight Singapore, Israel, the United States and Japan.
However, the technologies developed so far generally use reverse osmosis, which consumes a lot of energy and pressure, with low efficiency and the cost of use is very high, which simply scares away many potential buyers.
Faced with this complex scenario, Nanoseen emerged, with the innovative “NanoseenX” technology, the first in the world to filter seawater, through simple filtration, without using electrical energy, as it works with the support of gravity to filter salt water in nanomembranes ¹ , which retain impurities and salt in their pores and convert sea water into drinking water for human consumption.
Nanoseen, developer of NanoseenX, is a Tri-City startup, founded in 2020, made up of scientists, engineers and sustainability enthusiasts, whose mission is to create, develop and deliver nanotechnology solutions. Its headquarters are situated in the Gdynia Science and Technology Park, Poland.
It should be noted that NanoseenX does not cause environmental damage, as it does not emit carbon dioxide and its nanomembranes are biodegradable.
It is important to note that the technology is designed to filter water from the Baltic Sea, where the salinity is not very high, but it is in the research and development process so that it can also be used in different types of water.
According to Nanossen, a team of experts adjusts the composition of the membranes for a particular type of water, tests how long they can be used, and ultimately determines the device's life cycle. For example, for Baltic Sea water, it is a period of up to 200 days (about 1000 liters per day), including periods of regeneration. That's right, for a certain period of time it is possible to regenerate the membranes to increase their useful life.
NanoseenX technology is the cheapest way to obtain water from the water desalination and purification process. The cost of obtaining this water is 0.0001 USD/liter.
According to Bartosz Kruszka, Founder and Chairman of the Nanoseen Board, at the moment, commercial efforts are concentrated in Poland as well as in the Baltic Sea markets, including Sweden, Finland, Lithuania, Latvia, Estonia, Denmark and Germany and in 2023 started implementation of filtration systems on an industrial scale in the Philippines.
As interest in NanoseenX technology is high, Kruszka envisions the expansion of NanoseenX to many places around the world in the future.

¹ Nanomaterials are substances with particle sizes ranging from 1 to 100 nanometers. A nanometer is a unit of length in the metric system, equal to one billionth of a meter (0.000000001 m).
