UV-Anwendungen
Ultraviolet water disinfection is becoming more popular. Indeed, this is due to its simplicity and efficiency in obtaining water free of microbiological contaminants.
At 1H2O3, we have selected reliable suppliers with proven and durable solutions. This provides a significant positive impact on the environment.
Before presenting the various UV applications, let’s take a look at operation and maintenance.
UV System Maintenance
This ultraviolet water disinfection is an effective process for obtaining safe and drinkable water. Its process is usually similar from one device to another.
That’s why we briefly describe this part here.
But like all water treatment systems, a UV filter system requires regular maintenance. UV maintenance is relatively simple and hassle-free.
Only two components need to be cleaned or replaced regularly:
- UV lamp
- quartz sleeves
And the time interval between each cleaning depends on how often the system is used.
UV lamp
Unlike ordinary bulbs, UV lamps do not burn out, they solarize. That is, they reduce the intensity of the light waves to about 60% of what a new UV lamp provides. This parameter is often reached after one year or 9000 hours of continuous use.
Therefore, it is important for UV lamps to be:
- checked every year
- replaced every two years
Indeed, with time, it loses some of its radiation capacity.
The UV lamps we offer integrate this reduction in radiation and deliver the power for which they have been designed at the end of their life.
When replacing lamps, be sure to use lamps from the same manufacturer as the system being used.
The accounting of our UV bulbs is indicated on the online products
Quartz tube
Water that passes through a UV system often carries minerals, sediment, and other debris. These contaminants eventually accumulate on the UV quartz tube that protects the UV lamp.
It is therefore necessary to maintain it in order to prevent clogging in the tube. This buildup clouds the tube and prevents UV light from entering the water and operating efficiently. However, you have to think about replacing it in case of difficult cleaning. This process is easy to perform, as you only need to follow the manufacturer’s instructions. We recommend cleaning the quartz tube every year, and replacing it every three years. For more details, see the quartz sleeves page.
In this part, we will detail the various applications for ultraviolet water disinfection:
Quartz tube
What are the advantages of UV disinfection in the food industry?
UV disinfection offers an effective solution to eliminate up to 99.99% of pathogenic microorganisms, including viruses, bacteria and fungi, ensuring better food and beverage safety. It also extends the shelf life of products without altering their nutritional quality, while avoiding the use of chemicals
How is UV disinfection used in swimming pools?
In swimming pools, UV disinfection is integrated into the filtration system. The water passes in front of a UV lamp that eliminates microorganisms. This method significantly reduces the use of chemicals like chlorine, providing water that is gentler and less irritating to the skin and eyes.
Is UV disinfection suitable for domestic drinking water treatment?
Yes, UV disinfection is commonly used to treat drinking water in homes. It effectively eliminates pathogens without adding chemicals, preserving the natural taste and smell of the water. It is an ecological and safe solution to ensure the quality of the water consumed.
What are the industrial areas where UV disinfection is applied?
UV disinfection is used in a variety of industrial sectors, including:
Food industry : to disinfect water used in production processes.
Pharmaceutical industry : to ensure water sterility in the manufacture of medicines.
Wastewater treatment : to remove pathogens prior to water discharge or reuse.
This technology is appreciated for its efficiency and respect for the environment.
Is UV disinfection effective against chlorine-resistant microorganisms?
Yes, UV disinfection is particularly effective against microorganisms such as Giardia and Cryptosporidium, which are resistant to chlorine. UV-C light damages the DNA of these organisms, preventing them from reproducing and thus ensuring complete disinfection of the water.
