Aquazone Swimming Pool Systems
OZONE SWIMMING POOL SYSTEMS
Use ozone instead of chlorine
A TYPICAL LAYOUT
GetOzone offer the Aquazone Range of Atmospheric Air fed Corona Ozone Generators which are ideal for Residential and larger swimming pools.
The Aquazone Basic units as per the picture above have no Flow metre or Air driers which are included in the Aquazone Advanced range.
As a general rule for every 10000 litres you can apply 1 gram ozone. Therefore a 50000 litre pools should require a 5 gram ozonator

Why Ozonate your pool?
Ozone works 3000 times faster and is 1.5 times stronger than chlorine so is a very effective replacement for chemicals without the harmful effects of chlorine. The water in a properly ozonated pool will taste or smell similar to rain water with no chemical or other taints.
Better Disinfectant
Ozone disinfects pools faster and better than chlorine systems. When 0.1mg/L of ozone is in contact with bacteria E. coli, it will completely destroy it in less than 12 seconds.
Increased Comfort
Chlorine can be uncomfortable and even salt systems have the potential to irritate the skin, eyes, and airways of bathers. With ozone there is no strong residual chlorine odour, skin and eyes are not irritated, and bathers with respiratory issues are able to breathe freely and without issue.
Enhanced Water Quality
When ozone is applied to pool water, a process called “micro flocculation” occurs forcing many of the organic contaminants in the swimming pool to group together and easily filtered out by the ozone resistant sand filter. ( Preferably Clinobrite rather than sand)..
- Destroys 99.9% of Harmful Contaminants
- Oxidizes Cryptosporidium parvum, Giardia, and Other Chlorine Resistant Microorganisms
- Reduces Chemical Demand
- Increases Effectiveness of Residual Sanitizers
- Eliminates Chemical Odours, Irritations, and Will Not Damage Pool Systems
Why not ozone?
- Ozone has no residual life so minimum circulation times have to be adhered to.
- Initial Capital cost is high as a once off cost.
- Regular backwash and inspection is a must.
FAQ’s on Ozone in Pools and Spas
- Question 1. Why ozonise / ozonate my pool or spa?
Answer 1.
a. Generally pool owners who are concerned about harmful effects of chlorine will be interested in converting from chlorine or chemicals systems and/or salt chlorinators. In particular heated pools or spas with chlorine disinfectant systems can be harmful as the skin pores open up with the warm water and chlorine can be ingested in to the body.Health authorities in first world countries insist on a residual level of 2.5 to 3 ppm ( parts per million) chlorine in public pools for effective sanitation. At these levels the chlorine smell is very evident and uncomfortable and unhealthy to many…even if the water is sanitised! By including ozone in the circulation system it is possible to bring the levels of chlorine down to a much safer 1 ppm and the water is sanitised and safe for bathing.Competitive or regular swimmers will often refuse to swim in a chlorinated pool and Olympic and Municipal pools are generally ozonated for this reason.
b. Depending upon the cost of electricity or chemicals and the amount of circulation/pumping time, ozonated systems will be cost effective once the capital costs are amortised after 2 or 3 years. - Question 2. What size unit do I need for my pool.
Answer 2.Sizing depends upon many factors
a. Running time and output of the circulation pump. Generally speaking if the pump output is 1000 litres per hour 1 gram an hour of ozone will be sufficient to sanitise the passing stream.
b. Temperature of water. ( the colder the better).
c. Amount of bathers in the pool.
d. Capability or effectiveness of the ozone gas induction and mixing system. (A 1000 mg/hr ozone generator with an efficient mixing system could be as effective as a 5000 mg/hr generator and an inefficient mixing system). Ozone, being a gas, must be effectively introduced in to the water flow using a venturi and then thoroughly mixed with the water before entering the pool. There should be sufficient contact time for the ozone to mix with the water and to react before entering the pool. ( The longer the better).
e. Actual output of the ozone generator. Systems using atmospheric air as the feedgas will provide lower outputs at high humidity. The airflow determined by the venturi must match the ozone generator. ( Aquazone systems generally require between 3 and 5 litres of air per minute).The venturi suction is affected by the cleanliness of the filter or back pressure caused by a connected self cleaning vacuum system.
f. Amount of chemicals used by the owner.
If the pump is not running 24 hours per day, chemicals will be required to provide a residual control whilst the ozone is not being introduced.
Depending upon the shape of the pool it may be necessary to introduce chemicals in various corners where circulation of the water does not occur.
