The ozone system is a system used in closed circuits and bottled waters and is effective in this field. Ozone is a gas produced in its environment and is volatile. It provides disinfection in closed lines or bottled waters, but disappears quickly when it comes into contact with air. In water with a large surface area like a pool, its volatility will be much faster.
For this reason, if an ozone system is to be preferred, a system large enough to ozonate all pool water before bacteria forms in the pool and before ozone loses its effect must be installed. This will be much more costly compared to the ionization system. Additionally, there are many devices on the market that claim to produce ozone, but most are far from producing sufficient ozone.
However, since people who purchase cannot measure the ozone produced by the device, they think that installing the device is sufficient. If you decide on ozone, it would be beneficial to choose a brand that can measure the required amount of ozone for your pool tonnage and the ozone produced by the device.
The disadvantages of ozone are that ozone gas is a very toxic gas, the system is expensive, and therefore it is more complex compared to other systems. Much more qualified personnel is required for the maintenance and service of the ozone system compared to other systems. We can list the usage areas of ozone systems as bottling industry and chemical industry.
0.5-2 grams of ozone is required to disinfect one cubic meter of clean water. This amount depends on the contact time between water and ozone and the properties of the water. More ozone is required for the treatment of waters that are quite colored or rich in organic matter. The minimum contact time is 4 minutes.
Since ozone dissolves very little in water, good contact between ozone and water must be ensured. As the water temperature increases, the dissolution efficiency of ozone decreases. Ozone is 13 times more soluble than oxygen form. It is 3100 times faster disinfectant than chlorine. However, due to its short life, it loses its function by turning into oxygen form after minutes.
In experimental studies, it was concluded that the half-life of ozone in pool systems is 22 minutes. YILDIZ TECHNICAL UNIVERSITY
UV radiation is only effective where the radiation reaches. It is not effective in pool water. It can be used as an auxiliary in the water preparation process, but cannot perform this function alone. It is not included in TSE 11899. NATIONAL POOL INSTITUTE TECHNICAL COMMISSION STUDIES.
The most important disadvantage of UV disinfection is that it requires frequent lamp maintenance or replacement. Additionally, the wastewater must be highly treated (so that target microorganisms cannot find a place to hide from UV light).
Bacteria in water resist ultraviolet rays longer than in dry air. For bacteria to be killed, ultraviolet radiation must hit them directly. For this purpose, there should be no sediment in the water during disinfection.
Salt chlorine producing systems are based on the principle of producing chlorine from raw materials in the area where it will be used, instead of taking chlorine as a ready product. While this situation reduces input costs to some extent, the system used is still chlorination and all the disadvantages of chlorine will be experienced.
Additionally, as you will see in the attached circular, since the pool will again fall into the status of pools disinfected only with chlorine compounds, there will be no decrease in chlorine consumption.
Therefore, these alternative systems have significant disadvantages compared to copper ionization technology, both in terms of health and cost.
