Cleaning with Ozonated Water: What you need to know
Some cleaning chemicals used around the home can be hazardous, many may cause acute effects such as respiratory irritation, headache, sneezing, and watery eyes in sensitive individuals or allergy and asthma sufferers.
We at EcoVive advocate Toxic-Free Cleaning. One of the keystones of toxic-free cleaning for the home is using liquid ozone (ozonated water) to replace chemical disinfectants. Ozonated water is perhaps the most misunderstood and maligned technology that we promote, largely because of misunderstandings about ozone in general. Therefore, it has become the subject of undo concern.
To set the record straight, we’ve compiled a list of FAQs about Ozonated water.
How safe is Ozonated water?
Liquid ozone is in fact a strong oxidizer. However, this does not mean that it is corrosive or combustible in aqueous form (i.e. a solution of water). In residential and commercial cleaning applications it is completely safe and won’t harm bare skin. In fact, it may help to kill germs that your hands may have contacted during the cleaning process. Therefore, you don’t need to wear personal protective equipment like gloves as you would with harsh, chemical-based cleaning solutions.
Everyday someone dies from household chemical exposure. In fact, in 2000, cleaning products were responsible for nearly 10% of all toxic exposures reported to U.S. Poison Control Centers, accounting for 206,636 calls. Of these, 120,434 exposures involved children under six, who can swallow or spill cleaners stored or left open inside the home
How does liquid ozone work?
Ozone is a molecule of three oxygen atoms (O3) that is not stable and will breakdown quickly and form radicals having a high oxidation potential. This is what makes it a strong oxidizer and disinfectant. During the oxidation, only one oxygen atom is used for the chemical reaction forming with hydrogen into OH-radicals. Harmless to people, the ozone quickly attacks and eliminates contaminants it comes in contact with. The oxidization reacts with the cell walls of bacteria and viruses the same way hydrogen peroxide and iodine do, causing cell poration of the microbe, which leads to it’s death. The oxidation also removes electrons of molecules, eventually rendering them inert. In this way O3 kills the bacteria that cause odors, viruses that cause illness, as well as breaks down biofilm on surfaces that provide the food for microbes.
How long does ozone last
Ozone in any form has a 15 minute half-life. Which means that In 15 minutes half its solution has lost potency, at which point it is a better cleaning solution than disinfectant for the next few hours.
What residues will liquid ozone leave after it dries?
Contrary to chlorine, which always leaves an oxidation or disinfection byproduct, ozone simply will revert back to oxygen.
How strong is Ozonated water?
Ozone is often compared to bleach and other chlorinated products as they are used in many of the same disinfection applications. When used as such ozone has proven to be 50% stronger and 3000x faster than bleach. In regulated cleaning applications, EPA guidelines direct us toward disinfection with chlorine and ozone. For example, disinfecting with 1 ppm chlorine at a water temperature of 59°F and a pH of 7 requires a dwell time of 75 minutes. The disinfection efficiency achieved will be 99.9 percent. Assuming the same temperature and pH, a concentration of 1 mg/l of liquid ozone water achieves a disinfection efficiency of 99.9% in only 57 seconds. For this example giardia is the parasite used in the water sample because it is one of the most difficult microorganisms to kill. Ozone has many applications for both the residential and commercial customer. We covered cleaning using liquid ozone quite thoroughly by now. Ozone generators can be made for water treatment plants and are in use all over the world. There are applications for it in laundry and dish washing, but mostly in commercial or industrial settings.
Ozone is being used on both public and private pools as a means of disinfecting pool water and is being used in laundry washing systems. Another important application is air purification. As an oxidizer it attacks the bacteria at the cell level, killing them and their aerobic activity, which is what causes odors and areas of potential for infection.
