Advantages of UV Sterilizers Over Ozone Generators in the Swimming Pool Industry and Their Installation Methods

Ultraviolet disinfectors are widely used in the swimming pool industry and can effectively enhance the ultraviolet transmittance of pool water. As we know, transmittance is one of the key indicators for evaluating water quality. When ultraviolet light passes through a layer of water, its intensity diminishes because substances in the water absorb the UV radiation. However, since turbidity only reflects the presence of suspended particles in the water and does not necessarily indicate the concentration of dissolved substances, the rate of UV transmittance is not entirely correlated with turbidity or color. Ultraviolet light can oxidize organic compounds in the water and also disrupt the structure of turbid particles. Combined with filtration technologies, UV disinfection can continuously improve the water’s transmittance rate.

Moreover, traditional disinfection technologies pose certain health risks to humans because they generate various byproducts during the disinfection process, including diamines, triamines, and methane. Although ozone disinfection technology using ozone generators is well-established and highly effective at killing bacteria, it requires extensive daily maintenance due to its complex system, high initial investment costs, high operating expenses, and challenging operation procedures. This makes it demanding in terms of technical expertise for operators and thus unsuitable for most swimming facilities. On the other hand, ultraviolet (UV) disinfection technology boasts advantages such as high bactericidal efficiency, zero pollution, safe and reliable operation, and the absence of toxic byproducts. It is therefore one of the ideal disinfection methods.

To fully harness the ideal performance of ultraviolet disinfectors, we should pay close attention to equipment installation. Please see the following content.

1. If the ultraviolet disinfection unit is to be installed outdoors, it must be equipped with rain- and dust-proof facilities. During installation, vertical installation is strictly prohibited. The cylinder must not be subjected to external pressure, and it must not come into contact with the quartz casing at the inlet or outlet.
2. The device’s built-in quartz casing and UV lamp are fragile items. During transportation, installation, and use, they should be handled with care to avoid bumps and severe vibrations.
3. During installation, there should be a space of at least 1 meter and 0.5 meter at each end of the equipment (a space of 1.6 meters and 0.5 meter is required for high-power models) to facilitate lamp replacement. Additionally, a space of 0.5 meter should be reserved in front of the electrical control box for maintenance purposes.
4. The two ends of the equipment can serve as both an inlet and an outlet; one end functions as the outlet, and the customer can choose freely.
5. After installation is complete, you can first perform a water test. Once you’ve checked for any leaks, you may turn on the power. Only after all the lights are functioning normally for 3 to 5 minutes (as indicated by the indicator lights showing no abnormalities) should you begin supplying water.
