Stanford researchers design a more efficient and affordable desalination process
Ғылым және технология
Desalination - the conversion of saltwater to freshwater - has been limited by high operational costs. A new device capable of turning desalination waste into commercially valuable chemicals could make the process cheaper and more environmentally friendly.
Taking a new approach to an old problem, Stanford researchers have created a device that could make converting seawater to freshwater profitable and environmentally friendly. Their research, published in ACS Sustainable Chemistry & Engineering, outlines an efficient method for transforming water with very high concentrations of salt and chemicals, known as brine, into commercially valuable chemicals as part of the desalination process. The approach avoids the need for disposing potentially hazardous chemicals in local ecosystems.

Very informative
hopefully this is a water war effective solution, thanks for the upload
Love this! I've been brainstorming similiar methods to extract phosphates from aquaponic systems using various anode/cathode variations in tandem with a hydrolysis collection. Would love to pick your brain sometime if you have the opportunity! Thank you sir for the awesome discussion!
Tqs for the info
Why not completely dry the brine and sell it as salt rock to places that have snow? NJ and NY spend alot on salt for the roads when it snows.

Such Brine has various chemicals other than salt. It will take more power to separate salt of the brine.

too expensive to do so. They can get magnesium and lithium out of it and make way more $

Calculate the energy required to do this. Massive amounts. Just to make cheap rock salt to de-ice roads? Neither environmentally nor economically viable. THINK!

Need to have a better process to desalinate water. Heat the water that comes in with sun light.

How about we use solar panels to create power to heat the water and that would be a way to use the sun.
Isn’t there EXPERIMENTAL PROCESS of Generating ELECTRICITY USING SALT WATER? How about the waste Brine have Electrons? MAYBE BIG ENERGY DOES NOT WANT INDEPENDENCE FROM GRID SYSTEMS?

It's highly inefficient. You'd loose more power moving the brine than you'll gain from the brine.
Your language ???????

Desalination has a huge carbon footprint because of the energy required to pump against the high osmotic pressure on the membrane. Best source of water is from your toilet, via the local sanitation plant in your town... wherever you are. No need to be next to an ocean, much lower energy bill.

Unless there is a monstruous mining company that needs more water than the recycled by a city.
