Ozone – the Perfect Solution for Water Treatment!
Applying ozone to water has many benefits! Ozone is a natural and chemical-free treatment for water. And which are these benefits? How is the treatment made? What system or machine system or filter should we use for ozone water treatment?
If you want to know more about how ozone is an effective water purifier, keep reading this post, and these answers will be found!
Ozone has been used for Water Treatment purposes all over the world for more than 100 years. It is one of the most powerful water treatment compounds available today, due to its distinct and unique properties that allow disinfection of heavily water streams. It’s currently the most popular water treatment purification method used.
Properly used and handled, it is safe, natural, and extremely useful. This non-toxic agent has been proven to thoroughly disinfect the water, killing all pathogens, bacteria and virus while leaving no toxic residues in the water.
Ozone water treatment is the most effective method for eradicating toxins that are present in the water. It is a highly powerful oxidant that inactivates organic and inorganic materials, biological contaminants, bacteria, germs and virus.
Also, ozone is an excellent disinfectant and a powerful oxidant that can oxidize metals in water such as manganese, iron, and sulphur into insoluble particles. The ozone water treatment process has no chemicals.
How does it work?
Ozone has been proved to be one of the most effective disinfectants and is widely used to inactivate pathogens in drinking water, especially in Europe
Not only does ozone remove microorganisms from the water, but it also helps clean effectively filtration systems, removing odors from water. Another very important benefit is that no chemicals are added to the water, because ozone has unique proprieties of disinfection and oxidation, not leaving any residual.
Due to its excellent disinfection and oxidation properties, ozone is widely used for drinking water treatment. Ozone can be added at various points in the treatment system, such as during pre-oxidation, intermediate oxidation, or final disinfection.
Micropollutants such as pesticides can be found in surface water, but also increasingly in groundwater. In the European Union, there are strict drinking water standards for pesticides (0.1 μg l-1) for each compound.
Several studies show that ozone can be very effective for the oxidation of various pesticides. In Zevenbergen (The Netherlands), a water treatment plant demonstrated that three barriers (storage-ozonation-granular activated carbon (GAC) filter) are effective and safe enough for pesticide removal.
For 23 pesticides tested, more than 50% were sufficiently degraded ( > 80% degradation).
The following table provides an overview of the pesticides that are readily degraded by ozone. For very resistant pesticides, a higher ozone dose or the combination of ozone with hydrogen peroxide is recommended.
% Degradation of Pesticides Effectively Degradable by Ozonation
|Pesticide||pH 7,2 | 5ºC | O3/DOC = 1,0||pH 7,2 | 20ºC | O3/DOC = 1,0||pH 8,3 | 20ºC | O3/DOC = 1,0|
|MCPA (2-methyl-4-chlorophenoxyacetic acid)||83||87||90|
DOC – Dissolved Organic Carbon or DOC is a measurement of the amount of organic matter in water that can be passed through a filter, commonly 0.45 µm.
There are many benefits to use ozone in water treatment:
Strong disinfectant – ozone acts as a disinfectant and it treats the water against bacteria, virus and parasites such as Giardia and Cryptosporidium. Ozone is highly effective against all the microorganisms.
Powerful oxidant – Ozone is a powerful oxidizing agent and is very effective against essentially all odor causing organic materials and oxidizable inorganics such as iron, manganese and sulphide ions;
Taste and odor removal – Ozone effectively destroys color producing compounds, as the humic substances (primary cause of colour in natural water) by attacking the unsaturated bonds which give rise to this color;
Algae Removal – Ozone eliminates some algae or limits its growth. Ozone is also capable of inactivating certain zooplankton, e.g., mobile organisms, as the Notholca Caudata;
No residual effects – There are no harmful residuals that need to be removed after ozonization because ozone decomposes rapidly;
Purified water – the water treatment with ozone is 100% natural, no chemicals are added, and the water is safe, clean and purified.
Nowadays, ozone is used as a safe, natural and effective treatment not only used for pool or jacuzzi, it is also applied in drinking water treatment, food hygiene, and in some areas of medicine, especially dentistry.
A water treatment system that purifies water is the ideal solution for our daily lives! An ozone generator brings the benefits of Ozone to any tap, with our Tap Water System that you can find in our session below!
