Filter-free water purification

I found this article today about a filter-free and no-moving-parts water filtration system that relies on CO2 injection to ionize the water and encourage the non-water particles to separate from the water.  It seemed worth sharing.

There are a number of natural processes that produce CO2 (biogas production, for instance).  If this pans out, it's worth designing the output of a biogas upgrading process to feed the input of a water purification process.

Cheers.

This seems pretty nifty. I wonder if a solar panel+air+some device could be used to make carbon dioxide on site. If anyone know of such a co2 generator please share.
Otherwise yeast+sugar could be used. https://www.instructables.com/id/CO2-Generator/
