RSS develops device to harvest potable water from desert air

AMMAN — A team of researchers at the Royal Scientific Society (RSS), Jordan’s largest research institution, developed a machine that can utilize the most arid air as a reservoir for drinking water, according to the Jordan News Agency, Petra.

Utilizing water vapor in the form of humidity, the patented device is capable of producing up to 35 liters of water per day, even in Jordan’s arid, desert climate. The process can be carried out multiple times a day to deliver a continuous supply of clean drinking water.

Jordan is one of the world’s poorest nations in water resources, which are being depleted faster than they can be replenished. The problem is being exacerbated by climate change, which is causing spiked temperatures and prolonged heat spells.

To address this challenge, a team at the RSS’s Advanced Research Center set out three years ago to develop a solution that treats the atmosphere as an untapped reservoir.

The research team, led by Scientific Research Executive Director Kyle E. Cordova, and Staff Scientist Husam Al-Massad invented a novel atmospheric water-harvesting machine that selectively captures and collects humidity from the surrounding air and condenses it into liquid water.

The machine has been vetted, validated, and approved through a rigorous peer-review process, and the result has been published in Nature Communications, one of the world’s most prestigious scientific journals.

The device uses porous, molecular sponges that are designed to efficiently and selectively capture, concentrate, and condense water vapor from dry, desert air, utilizing cutting-edge technology. The water is released once the molecular sponge is full by raising air temperature.

The released water vapor is then condensed to yield liquid water that is filtered and mineralized for human consumption. This process can be driven by an external, solar-powered energy source.

The research team’s scientific report detailed how the machine operates using a proprietary algorithm that monitors climate fluctuations in real time to continuously optimize water production and power consumption.

This resulted in a 3-fold increase in daily water production, even in the arid desert.

Crucially, the cost per litre is as low as 6.5 US cents, and the water produced meets the national drinking standards of Jordan.

The RSS has registered a worldwide patent to commercialize the device through a spin-off company called AquaPoro Ventures Ltd, which aims to manufacture the machine in Jordan to bring water independence and security to families and communities by mid-2023.

The RSS said it saw the new technology as an important addition to an urgently-needed armory of tools to provide long-lasting global water solutions. اضافة اعلان
