Can seawater be drinkable?
The global research team has developed an important technology that can make large quantities of seawater safe to drink in less than 30 minutes. An invention that makes seawater drinkable in half an hour.
How can brackish water be made drinkable in an environmentally friendly and short time?

The global research team has developed an important technology that can make large quantities of seawater safe to drink in less than 30 minutes.
A statement from Australia's Monash University said the development would provide millions of people around the world with clean drinking water and use energy more efficiently than current sanitation methods.
"People living far away can benefit the most," Professor Hunting Wang, who led the project, told the BBC's Mendo.
How does this new invention work to make seawater drinkable?
This specially designed filter can produce hundreds of liters of drinking water per day and requires only sunlight to clean, making the process low energy, low cost and sustainable.
This advanced filter can be cleaned by solar energy.
Organometallic compounds or MOFs are used to make filters. They contain the metal from which the crystal material is made.
During the cleaning process, the filter, called PSP-MIL-53, first absorbs the salt and then exposes it to sunlight so that it can be recreated.
This process takes less than four minutes.
During this time, the filter is able to absorb the salt in the water.
What will be the standard of purification of this invention that will make seawater drinkable?
Water treatment standards
The World Health Organization recommends that good quality drinking water contains less than 600 milligrams per liter of total soluble solids (TDS).
Researchers have been able to recreate the MOF filter to achieve less than 500 mg of TDS and reuse in sunlight in just half an hour.
The process was successful in filtering harmful particles from the water and producing one kilogram of MOF 139.5 liters of clean water per day.
Brackish water passes through a tube. This tube absorbs salts without the use of light and purifies the water.
This new solar technology could be part of the solution to the future clean water problem.
Semi-brackish water has more soluble salts than freshwater and less soluble than seawater. So the process of cleaning them is reliable.
With the technology's low energy consumption and no need for chemicals during the process, Wang said the new solar-powered technology could be part of the solution to the future clean water problem.
"Solar energy has long been used for filtering, where water vapor is formed and freshwater is produced. But it takes many hours to produce enough water for home use.
"We use sunlight to recycle our materials and it only takes a few minutes."
Professor Wang led the study, which developed a filter to make seawater drinkable.
When asked about the cost of the new device, the professor said it would take a long time to make it cheaper for the public.
'Laboratory materials are not cheap. When it is mass-produced, the cost of production is expected to be significantly reduced.
"We hope that after further research and development, this material will be widely available and affordable."
