6 technologies used to create clean drinking water: taken from air, filtered seawater ...

According to Water.org, about 1 in 10 people in the world do not have access to safe and clean water, ie about 633 million people, so scientists have come up with many different solutions to help create Clean water for them to use. Every year, more new, lighter, cheaper and easier solutions are proposed or tested, ranging from drawing water from the air, turning seawater into fresh water or filtering water with UV rays.

Please refer to 6 very creative solutions below to know what people are doing to help the 633 million people mentioned above have clean water to use.

Warka water tower

Warka water tower is used to create clean water from the air.

It took years to design people to complete the idea of ​​Warka water tower, and earlier this year it began to be tested in a remote Ethiopian area to create clean water from the air. This award-winning design, which draws water from the dew particles and uses a giant circular structure made of woven bamboo into a giant "grid" . It also has a canvas to shade people when they catch water from the tower. If all goes well, Warka water tower will be mass-produced in 2019.

Water filter with UV light

This device helps reduce water filtration time from 48 hours to only 20 minutes.

Not all people who lack clean water live in drought-prone areas, sometimes they still have water throughout their neighborhoods but not one drink can be contaminated. Water filtration systems are often expensive and time-consuming to produce finished products, while Stanford University researchers' solutions with a single finger can reduce filtering time from 48 hours to 20 minutes . Currently the device is still being tested, but the prototype prototypes have proved feasible for this UV filter device.

Seawater refinery uses solar energy

This plant uses solar energy to operate electromagnetic water separators.

The project is called The Pipe , which was only launched this summer and promises to supply 5.68 billion liters of clean water to drought areas. The plant uses solar energy to operate water separators by electromagnetism, and salts containing salts will be fed through heat treatment tanks before being returned to the sea. In addition to the above benefits, The Pipe also attracted people's attention because its fancy looks like a floating art piece on the sea rather than a boring heavy industrial device.

The world's largest mist collection system

The world's largest mist filter is tested on the Moroccan desert region.

The world's largest mist filter uses giant nets to "catch" the dew on the Moroccan desert area and turn them into clean water. With an area of ​​over 600 square meters, this system takes advantage of the weather that is always surrounded by a dense fog of 6 months each year. Since its inception, every square mile of the system can get at most 64 liters of water that can be used for drinking. Combined with solar pumps and pipelines, water is being supplied to 400 local people. Before that, they had to work very hard to find water in this remote area.

Nano water treatment chip

The chip splits clean water from saltwater using electric current.

Cost is the main barrier to the problem of water shortage in the world, so researchers often focus on making smaller and individual solutions to reduce costs. In 2014, a joint research group between the University of Texas (USA) and Marburg University (Germany) created a chip to separate clean water from saltwater by using electricity. At an early stage, the chip can run only with a normal battery. Okeanos Technology start-up company was established to continue research and product development.

Carnegie Perth Wave Energy Project

The device that looks like a buoy is released on Perth coast in western Australia.

This project performs two tasks simultaneously: creating clean energy from the movement of waves on the ocean, combined with the ability to filter salt out of the sea. The device that looks like a buoy is released on the coast of Perth, located in western Australia, where clean energy use is always a priority to not affect the environment. Every 3 buoys will form a system that generates 240 kilowatts of electricity. They are also connected to the seabed by a hydraulic pump to push water through turbines. A portion of the energy generated will be used for water purifiers, the rest will follow the wire that connects to the local grid. This is part of a long-term plan to create clean drinking water for the people here.
