New York's Columbia University Scientists discover a game-changing way to remove salt from water called Temperature Swing Solvent Extraction
The process is called Temperature Swing Solvent Extraction and it's designed to purify hypersaline brines (water that contains a high concentration of salts, making it up to seven times as salty as seawater). This kind of wastewater is produced by industrial processes and during oil and gas production, and it poses a major pollution risk to groundwater.
What's most exciting about the process is its implications. The team was able to remove up to 98.4% of the salt, which is comparable to the current "gold standard" process, reverse osmosis. But unlike reverse osmosis or other methods of desalination, this process doesn't require high temperatures or high pressures -- just a low-grade heat of less than 70 C (158 F).
And that makes it a game changer -- both for treating wastewater and even creating drinking water fit for human consumption.
Current methods are very expensive and consume a lot of power so if this is actually as efficient and is scalable then it could be a game changer. Water is getting scarcer and is more valuable to life than most other commodities.
