Pros and cons of ozone water
Benefits
-
Effectiveness
Ozone is a powerful oxidizer that kills bacteria and viruses within seconds, and has stronger disinfectant properties than chlorine.
-
Chemical free
Ozone water treatment does not add chemicals to water and any wastewater produced is safe to enter waterways and drains.
-
Tried-and-true technology
Ozone water treatment is a tried-and-true technology that has been used to treat municipal water supplies since the early 1900s. A water treatment plant in Nice, France began using ozone water treatment commercially in 1906, and today it is used at more than 2,000 installations worldwide.
-
Speed
Ozone water treatment is incredibly fast. Most water treatment systems require extended contact time to eliminate or reduce contaminants, but ozone works in mere seconds.
Down sides
-
Cost
Ozone water treatment is expensive compared to more well-known water treatment methods, such as chlorination.
-
Difficult to store
Ozone has a short half-life once dissolved in water, as its natural reaction is to turn back into oxygen and needs to be made in your home and can’t be stored for this type of water treatment.
-
Potential toxicity in extreme doses
High concentrations of ozone can irritate your lungs and cause you to cough temporarily.
Ozone For Clean Drinking Water
Independent studies show that water filters add more bacteria to water as filters are not changed and water sitting around causes bacterial growth. For filters to remove bacteria the absolute pore size needs to be tiny or <0.1 micrometer, which is 10 times smaller than the EPA standard.
A wide range of disease causing microorganisms such as Giardia, Cryptosporidium, Salmonella, Shigella, Campylobacter, some strains of Escherichia coli (E. coli), cyanobacteria (blue green algae), Rotavirus, Norovirus, and Hepatitis A virus have been found in tank and bore water from NSW Health reports. Independent studies show that water filters add more bacteria to water as filters are not changed and water sitting around causes bacterial growth. For filters to remove bacteria the absolute pore size needs to be tiny or <0.1 micrometer, which is 10 times smaller than the EPA standard.
FAQ
Are cheaper alternatives like chlorine better than ozone?
When comparing disinfection efficiency, ozone is 25x more effective than Hypochlorous acid (HOCL), 2500x better than Hypochlorite (OCL) and 5000x more than Chloramine (NH2CL)
| Disinfectant | Bacteria | Viruses | Spores | Cysts |
|---|---|---|---|---|
| Ozone | 500 | 5 | 2 | 0.5 |
| Chlorine as HOCL | 20 | 1 | 0.05 | 0.05 |
| Chlorine as OCL | 0.2 | 0.02 | 0.0005 | 0.005 |
| Chlorine as NHCL | 0.1 | 0.005 | 0.001 | 0.02 |
Is the ozone generator easy to install?
It’s so simple, you can do it yourself. If you follow the step by step procedure in the manual provided, you will see that you need to attach the ozonator to an existing faucet by screwing in a fitting.
How does the unit compare with a UV steriliser?
The UV steriliser works differently. It has no oxidizing power, therefore it cannot change the taste of the water. The steriliser merely inactivates the reproductive cells, while the ozone literally destroys the cell.
Does ozone affect the taste of water?
Ozone produces no harmful byproducts. Unused ozone simply reverts back to normal oxygen and raises the level of dissolved oxygen in the water. This makes the water healthy, sparkling and tastes great.
Does ozone affect the smell of water?
Tank water can often have unpleasant tastes and odours. This is often caused by contamination from decomposing birds or animals and other organic molecules. Even smoke from the fireplace can cause tank water to taste odd.
During times with little rain, high temperatures can cause tank water to taste unpleasant to even the “long-time” rainwater drinker.
Ozone rapidly breaks down the organic molecules which cause tank water to taste stale.
Is ozone expensive to run?
Elavo ozone generators use a little electricity; comparable to a small household light bulb, about 20 cents per day. You don’t need to regularly buy any chemicals or expensive UV lamps. The ozone producing cell has a life expectancy of 5 years.
Do I still need a water filter with ozone?
Ozone has the ability to kill bacteria and viruses in a natural and healthy way, unlike any other substance. For larger organic matter like leaves or dirt that might find its way into water tanks we recommend using filters to remove those larger compounds.
