How is Ozone Applied in a SPA?
Everyone who has a SPA pool wants cleanest, clearest, softest and freshest water. Ozone is a powerful oxidant that can be used to remove pollutants from water and disinfect the water like chlorine. Ozone has been a standard in most SPA pools for many years since it will keep the water clean without the use of chemicals. Most of the ozone used for SPA pool water disinfection is produced by corona discharge. It is a powerful and reliable ozone generation option. And by an ozone generators, oxygen in the air can be converted into ozone for later use.
How Ozone Works
Similar to the use of ozone in family swimming pool water treatment, ozone oxidation is a process that breaks down bacteria, fungi, viruses, and other microorganisms. The oxidation will attacks the lipids to break through their cell walls and further destroy contents of the cells. Ozone can instantly kill hazardous microorganisms and even chlorine-resistant microbes such as cryptosporidium.
Then, after the oxidation process, a filtration system can remove the disparate parts of the broken down containments and make the water clean and shiny.
Like the most common chemical disinfectants used in SPA pools which are chlorine, bromine and hydrogen peroxide, ozone is a powerful disinfectant. The introduction of ozone can reduce the use of these chemicals.
Chlorine and bromine use a similar reduce-oxidation process to keep a SPA system clean. But it will lead to the production of chemical by-products that will eventually accumulate in the system. These byproducts produce harsh chemical odors and corrosive water that can cause skin irritation. Once the accumulation of chemical byproducts reaches a certain level, the only solution is to drain all the water and refill it with fresh water, resulting in an increased consumption of water.
In the recent decades, ozone’s high efficiency, effectiveness, and comparatively harmless nature have given its application an explosive growth in the spa pool industry.
Benefits from the Use of Ozone
Ozone is an ideal disinfectant for SPA water treatment. As a natural water purification and sterilization method, ozone treatment has the following advantages over common chemicals:
- Instantly kills algae, bacteria, viruses and chlorine-resistant microbes in SPA water
- Fast oxidation and destruction of organic pollutants such as sweat, body oil and dead skin
- Oxidize and destroy inorganic pollutants such as metals, suntan lotion, cosmetics, and chemical byproducts caused by bromine and chlorine
- Reduce the amount of chlorine and bromine required to keep a SPA system clean by up to 30%
- Reduce the production of chloramines and odors in the water
- Gather the destroyed dissolved solids together for an easy filtration
- Easier to use and control than chemical solutions
Is Chlorine Still Needed?
It is important to note that ozone cannot completely replace SPA pool chemicals such as chlorine and bromine. Chlorine and bromine can remain in the water as soluble chemicals and continue to function. The use of ozone is intended to reduce the reliance on such chemicals, thereby reducing unnecessary labor work and improving affordability.
Is Ozone in a SPA pool harmful?
Ozone treatment is a solution that has been using for decades. There is no evidence that its use in SPA pools is harmful on health. It is as safe to use as other conventional chemical disinfectants. The fact that ozone can provide highly sterilized water for fish and other aquatic organisms living in an aquarium demonstrates its safety and reliability in water treatment practice.
Does Ozone Cause Any Damage?
If not used properly, any oxidant in too high a concentration may cause damage to the plastic parts, shell, headrests and cover in SPA pool. Ozone will not cause any harm on the equipment when it is used at an appropriate concentration. Some of the ozone applications with actual damage to SPA pools have been caused by the installation of a wrong ozone equipment or the use of a too high ozone concentration.
