Wow, that’s incredible. Since it uses electricity for it’s energy input, this could be readily adapted for use in remote areas powered by solar plus battery. Even in Western nations this is a boon to treat well water sources instead of shock chlorination.
This combined with GAC filtration can produce very clean water anywhere you can get sunlight.
It needs gold and platinum catalyst. The trouble would be there would be no catalyst in the plant to process water, the day after it is deployed in a remote area.
The amount of electricity required wasn't mentioned, so while I'm hopeful that you're right I'm worried that the energy requirements will be prohibitive to adoption in many areas.
