Treating Wastewater with Shockwaves

Dec-22-19 A new method of treating wastewater from nuclear reactors relies on shock waves to remove the radioactive contaminants and allow the rest of the water to be recycled.

The team from MIT developed the technology as way to remove the minor contaminants that infiltrate the cooling system of the reactor on a daily basis. The system relies on shock electrodialysis, which generates a deionization shockwave in the water that forces ions to a charged porous membrane in the side of the tube. The team discovered that isotopes of cobalt and cesium, two radionuclide contaminants commonly found in nuclear reactor wastewater, can be selectively removed from the water in this fashion, making it suitable for reuse in cooling.
