1. What is De Nora UV Technology?
De Nora UV technology is an advanced disinfection method employing ultraviolet (UV) light to neutralize harmful microorganisms in water, wastewater, and industrial processes. UV disinfection deactivates the DNA of bacteria, viruses, and protozoa, preventing them from reproducing and causing infection. According to research from the World Health Organization (WHO) in July 2023, UV disinfection is a highly effective method, achieving up to 99.99% reduction in pathogens without adding chemicals.
1.1 Core Components of De Nora UV Systems
De Nora UV systems comprise several key components working in synergy to ensure efficient disinfection:
- UV Lamps: These are the heart of the system, emitting UV-C light at a wavelength of approximately 254 nanometers, which is optimal for disrupting the DNA of microorganisms.
- Quartz Sleeves: These protect the UV lamps from the water while allowing UV light to pass through with minimal loss.
- Reactor Chamber: This is where the water flows past the UV lamps, ensuring sufficient exposure time for effective disinfection.
- Monitoring and Control System: This monitors the UV intensity, water flow rate, and other parameters to ensure the system operates within optimal conditions.
- Wiper System: This keeps the quartz sleeves clean, preventing fouling and maintaining UV transmittance efficiency.
1.2 How Does UV Disinfection Work?
UV disinfection is a physical process, not a chemical one. Here’s a step-by-step explanation:
- UV-C Light Emission: The UV lamps emit UV-C light, which penetrates the cell walls of microorganisms.
- DNA Disruption: The UV-C light is absorbed by the DNA of the microorganisms, causing thymine dimers to form.
- Inactivation: These dimers prevent the DNA from replicating, effectively inactivating the microorganisms.
- Disinfection: The treated water is now disinfected and safe for its intended use.
This process is rapid, requiring only seconds of exposure to the UV light, and it doesn’t alter the taste, odor, or chemical composition of the water.
1.3 Applications of De Nora UV Technology
De Nora UV technology finds application across a wide range of sectors, each benefiting from its unique advantages:
