To set the record straight, we’ve compiled a list of FAQs that we’ve received and answered for clients.
The concern with liquid ozone tends to be around it off-gassing and becoming gaseous which dissolved at proper levels and sprayed at safe pressures won’t do (see #5 below). That being said, nobody has ever died of liquid ozone exposure, whereas every day someone dies from household chemical exposure. In fact, cleaning staff with asthma using our product say their breathing is perfect after working with it for 8 hours, contrary to the effect chemicals had on their breathing by the end of a shift.
No. There is much confusion between liquid ozone and atmospheric ozone. However, high-atmospheric (gaseous) ozone concentrations are bad for asthma and allergy suffers. It can contribute to those Code Red days which the weatherman warns us about. Atmospheric ozone is created by Mother Nature to try to break down air pollutants like NOX, VOCs, dust and allergens. So on those Code Red days, more ozone is being produced naturally because there are more VOCs in the air. Ozone gas is an indicator that there are other atmospheric contaminants that also affect asthma and allergy sufferers like VOCs, nitrogen oxides, dust and pollen. Being quicker and easier to measure than the thousands of air pollutants, ozone gets a bad rap.
Man-made atmospheric ozone an also be produced by air purifying generators and filters to deodorize and disinfect rooms like operating rooms, hotel rooms, and even weather-damaged homes. Allergy and asthma sufferers should indeed be wary of such high concentration applications.
4. How much ozone do liquid ozone cleaning solutions contain?
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.
8. How is liquid ozone produced?
Ozone in water can be produced with an electrolytic ozone generating cell, or via corona discharge and dissolved into water via an ozone injection system. Smaller systems or systems with ulltra-pure water can use an electrolytic cell. All larger and industrial systems will use a corona discharge ozone generator and injection system.
Ozone has many applications on the home and commercially. 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 generators have been used on both public and private pools as a means of disinfecting pool water. Similarly, some aquariums use it to keep water fresh and germ-free. 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.
SB-100 Ozone Spray Bottle
The SB100 Ozone Spray bottle uses an electrolytic ozone generating cell to produce ozone in water as the bottle is used. No chance of low ozone levels as ozone is produced real-time while used. Great for small scale cleaning applications
Ozone Injection Systems
+
For larger scale applications an ozone water system can be used. Ozone levels in water of 3-5 ppm can be created easily at water flow-rates from 3 – 300 GPM.
