A New Invention Has Been Discovered That Will Make Salt Water Drinkable In Minutes!

By  | 

Technology that can make salty or brackish water potable can save the lives of many people globally, and that is why countless scientists strive to do this in their projects.

A new invention developed in Australia is the most promising ever. Using a more efficient process than existing techniques, it is possible to purify the water with sunlight and metal-organic framework compounds (MOF) in just half an hour.

Also, this invention is both inexpensive and permanent and can be used repeatedly! Moreover, the produced water meets the standards of the World Health Organization. In a day, approximately 139.5 liters of clean water are extracted from 1 kilogram of MOF material (according to early tests).

After only four minutes of sun exposure, the substance releases all the salt ions it has absorbed from the water and is ready to be used again.

“A lot of energy is spent in thermal desalination processes by evaporation,” said Huanting Wang, a chemical engineer at Monash University. Other technologies such as reverse osmosis also have some disadvantages, including high energy consumption and chemical use in membrane cleaning and dechlorination. Sunlight is the most abundant and renewable energy source. “Our development of the adsorbent-based desalination process using sunlight for regeneration provides both an environmentally sustainable solution and energy-efficient,” he said.

The first water purification system made using MOF

Researchers have invented a new metal-organic framework called PSP-MIL-53. Some of this material is produced from a substance called MIL-53, which is known to react to water and carbon dioxide.

While this is considered to be the first water treatment system made using MOF, the PSP-MIL-53 item mentioned above also offers researchers different options.

MOFs are generally very porous materials. When even a teaspoon of the substance is compressed, it can open up as much space as a football field. In other words, this new system can be installed in pipes and other water systems, leading to the removal of clean water.

“Desalination has been used to address growing water scarcity globally. Thanks to the high availability of saltwater and the visible reliability of desalination processes, the new system can be integrated into the existing system with minimal health risk. he spoke.

New solutions do not come fast enough because, according to the World Health Organization, around 785 million people globally have to walk for half an hour to where they live for clean water supply. The problem is getting worse with global warming.

Seawater, which makes up about 97 percent of the water in the world, can be a source of life for us if materials such as PSP-MIL-53 are suitable.

Although it is not clear how close researchers are to a system that can be used in practice; It is very promising to know that other projects using ultraviolet light, graphene filters, sunlight, and hydrogels are underway. So much so that scientists are even investigating methods of extracting water particles from the air.

“Our work is reducing energy demand, finding ways to desalinate water and use solar energy to improve its sustainability. These metal-organic framework compounds (MOF) produced can functionalize low-energy and environmentally friendly mineral extraction methods for sustainable mining and other related applications, ”he said.

The research has been published in Nature Sustainability.
