Hello Mariana; Ozone ...

Hello Mariana; Ozone abilities have been known for a while. These days it is used as a last resort if the purification system has no access to modern technology or a perceived high cost of this new technology. A current drawback on the use of ozone is the elimination of the beneficial nutrients in the water. Those nutrients have to be added back or the "cleaned water" itself will become a secondary toxin meaning the lack of natural nutrients are missing. Sort of like sailors on naval ship many years ago  went for years on voyages with no fruit. But they did not get the minimal amount of nutrients to maintain their health. Identical to ozone.  Fortunately nature already has a perfect solution. In natures recycling system their is zero waste. Microbes from the RNA microbial group biodegrade the waste to the elemental state. No residue. Only nutrients they are needed to keep all life forms working within their established parameters.  Those "toxic metals" will be chelated by the same group. So if the primary question is device to measure Ozone ppm levels my answer is why? If clean potable drinking water regardless of the waste in it can be cost effectively applied then the answer is yes.  Kinda makes the water shortages around the world look like a man made crisis. Easily fixable and for pennies.
