UV Sterilization Overview
Ultraviolet water treatment systems (UV sterilisers) are essential for eliminating bacteria in water supplies. Commonly used for well, spring, and borehole water, these systems ensure safety and compliance with increasing legislation in food and drink industries.
As a natural component of sunlight, UV rays provide one of the safest disinfection methods. No chemicals are added, meaning there is no risk of overdosing or unpleasant taste, while effectively neutralizing viruses, bacteria, and cysts.

How It Works
The UV sterilizer utilizes a germicidal fluorescent lamp producing light at approximately 254 nanometers. As water passes over the bulb, the radiation penetrates microorganisms, mutating their DNA and preventing growth or multiplication.
Primary Applications:
- Food processing: Juices, milk, beer, and canned goods.
- Hospitals and laboratories for pathogenic water disinfection.
- Residential buildings, hotels, and restaurants.
- Aquaculture: Shellfish, fish cleaning, and seawater breeding.
- Industrial cooling systems and swimming pools.

Frequently Asked Questions
Q1: What is the main purpose of a UV sterilizer?
A: It is used to control infections by stopping the spread of microorganisms through the water and to control free-floating algae in ponds and industrial systems.
Q2: Does UV treatment affect the taste of water?
A: No. UV treatment is a physical process, not a chemical one. No chemicals are added, so the taste and odor of the water remain unchanged.
Q3: What wavelength is used for disinfection?
A: The system utilizes a germicidal wavelength of approximately 254 nanometers, which is highly effective at mutating microbial DNA.
Q4: Can this system treat raw sewage?
A: No, the system is not intended for raw sewage or water with obvious intentional contamination. It is designed for clear water disinfection.
Q5: What water quality is required for effective treatment?
A: For best results, water should have low iron content (less than 0.3 mg/L) and high clarity to allow the UV rays to penetrate effectively.
Q6: Are OEM and ODM services available?
A: Yes, both OEM and ODM orders are available for various water treatment systems including RO, NF, and UF systems.
