Brackish to Fresh Water – MIT and Jain Invention

There is more salty ground water than fresh and drinkable ones, despite advancements, there are still rural areas that are unfortunate of not having electric powered desalination plants that would provide them with drinkable water. When drought comes or circumstances happen where water seems to be in small volume or a little impossible, MIT and Jain Irrigation System developed a method that will surely be of great help to everyone.

Why Is It Important to Desalinate Salty Water

Though the harmful effect of drinking high level of salted water does not happen immediately, especially when you are taking in too much and regularly, the long term effect of it would be dangerous.

The most common early side effects of consuming salty water is dehydration, dry mouth, rapid palpitation of the heart, and lower blood pressure. You might also feel dizzy most of the time or suffer severe headaches. Higher amount of intake might also result to vomiting, loss of appetite and consciousness, or even having blood on your stool.

It is important for one to know the harm of consuming higher dose of salty water, long term danger would damage your kidney and it might be harder to produce urine since there is less usable water inside of your body. Severe dehydration could also result to seizures and even death if not acted upon immediately.

Salty No More

Massachusetts Institute of Technology (MIT) together with Jain Irrigation System developed a method that would produce clean drinking water using brackish waters.  With the use of the sun’s benefit, places with less water or rural areas would be able to enjoy drinkable water minus the salt and contaminants.

The solar powered machine is capable of dissolving and diminishing the salt out of the water, other than giving you cleaner tasting water, the machine could also disinfect the water and get rid of contaminants to make it drinkable and usable for irrigation; this is made possible by ultraviolet rays.

So how does electrodialysis work? It bypasses stream of water in between electrodes that has opposite charges, since salt in water is compounded with positive and negative ions, the electrodes will pull the ions out of the water and then produces clean water free from salt.

This method or machine is also known as a “photovoltaic-powered electrodialysis reversal system”, this is known due to its low-energy consumption that would work great on rural areas or undeveloped societies. Despite being low cost, this is environmentally sustainable and reliable to produce useable water for consumption or for agricultural purposes.
