Wouldn’t the chlorine oxidize the toxin or would an even stronger oxidizer be required like hydrogen peroxide or ozone? Are the toxin molecules small enough to pass through RO membranes?
I don’t the toxins physical size, but it probably could not pass through an RO membrane. My choice would be ozone. That stuff essentially rips any organic molecule to shreds. If it has nothing else to do in water it can form H2O2. Very interesting stuff.
