THIS NANO-MEMBRANE DESALINATOR DOES NOT NEED AN ENERGY SUPPLY
The gravity-powered desalinator can also remove nano-plastics and bacteria from water using cheap and scalable nano-membranes
According to the World Health Organization, 829,000 people are estimated to die each year from diarrhoea caused by unsafe drinking water, sanitation, and hand hygiene. At the same time, global warming is making it harder to ensure adequate supplies of fresh water in many places. Desalination is one solution to this problem and startup Nanoseen is working to make this process cheaper and more efficient with its nanotechnology filters.
The filtration technology is called NanoseenX, and uses specially created nanomembranes with pores ranging in size 0.1 to 0.8 nanometres, which trap different impurities and salts. Depending on the salinity of the water and level of contamination, between 2 and 20 nanomembranes are used, which are arranged in cascades or as a ‘sandwich’ inside a cylinder-shaped device. No external power is used as the system relies on gravity to carry out the filtration process.
In addition to removing salt, Nanoseen claims that the system can purify any polluted water, turning it into drinking water in two to five minutes.
Further, the nanomembranes can be used in existing equipment in water treatment plants. The membranes are scalable and, at a cost of around $0.08 to $0.50 per nanomembrane, they are one of the cheapest solutions available in the market today.
Nanoseen is now looking for further investors to enable them to bring NanoseenX to market and we wish them all success.
