About Ozone and Water Treatment

Ozone is an extremely powerful oxidizing agent which means it’s good at killing stuff like bacteria, micro-organisms (and destroying the rubber gloves you might be handling it with)!

Ozone is a colourless, unstable gas made up of three oxygen atoms.  It is produced (naturally or human-made) from oxygen with the use of power – usually electrical current. Nature produces it during lighting storms. Ozone’s distinct odour is sometimes noticeable after a powerful electrical storm.

Ozone quickly degrades back to oxygen while simultaneously releasing a free radical in the form of a free oxygen atom. This free oxygen radical is highly reactive and the oxidizing agent that makes ozone so caustic, an efficient disinfectant and eliminator of bad tastes and odours.

Ozone is more effective than chlorine
Because ozone is more effective than chlorine at killing bacteria and viruses, it is commonly used in Europe and Asia for water disinfection. Chlorine remains the dominant disinfectant in North America.

The oxidizing properties of ozone are also used to transform unwanted concentrations of iron, manganese and hydrogen sulfide in water into insoluble particles that can be removed by filtration.

Advantages to disinfection with ozone
1. Ozone has a very strong oxidizing power with a short reaction time. It is quickly effective against bacteria, viruses and microorganisms with stronger germicidal properties then chlorination.

2. Ozone can eliminate a wide variety of other water quality problems including some inorganic and organic contaminants, bad taste and odor.

3. Ozonation can treat water without the use of chemicals.

Disadvantages to disinfection with ozone
1. Equipment, operational and maintenance costs for ozone generation are involved and expensive.

2. Ozonation provides no germicidal or disinfection residual to inhibit or prevent regrowth.

3. Ozonation produces carcinogenic disinfectant by-products.

4. Ozone is less soluble in water than chlorine and may require special mixing techniques.

6.There are potential fire hazards and toxicity issues associated with ozone generation.
