Product Description:
1、 Principle of UV disinfection
Ultraviolet light is a type of light that cannot be seen by the naked eye, and can be divided into UVB (315~400nm), UVB (280~315nm), and UVC (200~280nm) according to different wavelengths. UVC is most easily absorbed by DNA (ribonucleic acid), and UV disinfection systems use UVC.
Senwei UV sterilization equipment integrates comprehensive disciplines such as optics, microbiology, mechanics, chemistry, electronics, and fluid mechanics. The strong UV-C light generated by a specially designed high-efficiency, high-intensity, and long-life UV-C light generating device is used to irradiate flowing water. When bacteria, viruses, algae and other organisms in water are exposed to a certain dose of ultraviolet C light (wavelength 253.7nm), the DNA and RNA structures of their cells are destroyed, and cell regeneration cannot proceed, thus achieving the purpose of water disinfection and purification.
The 185nm spectral line generates ozone in the air, which can have bactericidal and deodorizing effects. The 185nm spectral line can also decompose organic molecules in water, generate hydrogen radicals, and ultimately oxidize organic molecules in water to carbon dioxide, achieving the goal of removing TOC.

Ultraviolet disinfection does not produce any secondary pollutants and belongs to the latest generation of disinfection technology internationally. It has gradually become a mainstream disinfection method in developed Western countries due to its high efficiency, broad-spectrum, low cost, long lifespan, large water volume, and pollution-free advantages that cannot be compared to other disinfection methods.

2、 Application scope
Widely used in various water bodies (tap water, purified water, sewage, seawater, etc.) and air disinfection fields, suitable for disinfection requirements in various industries. Its main application areas include:
● Water purification and disinfection: tap water, secondary water supply, direct drinking water, purified water, aquaculture, food and aquatic product processing water, beverage water, pharmaceutical water, electronic high-purity water, etc
● Sewage disinfection: municipal sewage, recycled water, hospital sewage, slaughterhouse wastewater, oilfield reinjection water
● Circulating water disinfection: swimming pool water, landscape water, industrial circulating cooling water
Purification of shellfish, disinfection of agricultural irrigation water, and removal of algae from large water bodies
Disinfection of water for military bases, field operations, aircraft, ships, and submarines
● Air disinfection of central air conditioning system

3、 Characteristics of UV sterilization
1. Widely used for sterilization, it works on almost all microorganisms, bacteria, viruses, and bathroom organisms. And for parasitic insects such as cryptosporidium and giardia, which pose great harm to humans, chlorine and even ozone cannot effectively kill them
2. Fast sterilization, high sterilization rate, general microorganisms and bacteria can be killed within a few seconds
3. Environmentally friendly and safe, with no secondary pollution, pure physical sterilization, and no other side effects
4. Low operation and maintenance costs
5. Continuous high flow disinfection
6. Compact structure and small footprint
7. Quick and simple installation, easy maintenance and upkeep
