Principle for UV sterilization
All forms of life known on the earth exist on the basis of DNA and RNA for reproduction and existence. DNA and RNA are both composed of 4 kinds of chemical substance units.
A--Adenine
T--Thymine
C--Cytosine
G--Guanine (the basic component for the nucleic acid)
In time of cell reproduction, the long chains inside DNA are opened when Unit A in each chain will look for and connect with Unit T. Each long chain can reproduce an identical chain to the chain freshly split, restore the complete DNA before splitting and serve as the foundation for the new-borne cells. However, the ultraviolet at a wave length of 240-270nm is able to break the capacity of DNA to produced protein and reproduction. Once the DNA and RNA of bacteria and viruses are damaged, their capacity to produce protein and reproduction are both lost. As the bacteria and viruses usually have a very short life cycle, those will soon perish that cannot reproduce.
The effective of UV sterilization is often expressed in killing ratio, e.g., 99.9%. Namely, 99.9% of the original bacteria have been killed and only 0.1% exists, or, 1/1 000 has survived. As 1000 is the 3 in 103 or in log, it is habitually to express the killing ratio with 310g. The killing ratio of ultraviolet depends on two factors: 1, ultraviolet intensity (I); and 2, irradiation time (T).

Advantages of Modern UV C Disinfection)
The UV C Disinfection Technology has been widely accepted by the world for its superior effect in disinfection on cell viruses and other Factors to be Considered Liquid chlorine disinfection Chlorine dioxide disinfection Ozone disinfection LW disinfection pathogenic agents. UVC water disinfection technology has the following obvious advantages.

High-efficiency sterilization
Sterilization of cell viruses with UV C is generally within one second. In comparison, the traditional UV and Cl and Ozone Methods takes 20 min to one hour to match the effect of UVC.

No secondary pollution
As the UV-c Technology can be controlled within the scope of killing the bacteria or viruses only and it is unnecessary to add any chemicals, it Operation complexity Simple to middle grade Simple to middle grade will not cause the secondary pollution to the water body and the surround environment. Meanwhile, it will not change any component of the water.

It makes continuous mass sterilization possible.
The modern UV-C disinfection equipment can work 24 hours a day and 365 days a year. Except for the general maintenance within the fixed time, the optimum operation condition is the 24-hour continuous operation.

Operation and maintenance is simple and easy and of low cost.
With the improvement of UV-C core technology, the UV-C disinfection technology is not only the means of the highest disinfection rate of all the disinfection methods but also the simplest and easiest in operation and maintenance and of the lowest cost, reaching RMB 0.004 Yuan/T of water. Therefore, cost performance ratio is the highest of all the disinfection technologies. It has the high efficiency advantage superior to other sterilization technologies but also is the lowest in cost and expenses for operation and maintenance.

Safe and Reliable Operation
In terms of the traditional sterilization technology, like the methods of using the chloride or ozone, the disinfectant itself is highly toxic, flammable and explosive. Application of these substances causes latent threat to the site operators, the surrounding environment and the nearby residents. The modern ultraviolet disinfection system, however, does not bear such potential risks.

Notes:
1. Device Power: 220V/ 50HZ, service life of the UV light tube is ≥9000 hours.
2. This Table for Technical Parameters lists the units which can be used for disinfection of such pure water as: tap water, purified water, water for
aquaculture and livestock and poultry husbandry, water for food processing, supply of water of different qualities and water for medical
purposes, etc.
3. The sterilization efficiency depends on the transparency, impurities and temperature of the water and the sterilization efficiency is 99% or
designed for special purposes.
4. YLCn refers to the thread filling while YLC refers to the joint of flange adapter.
5.Various of. advanced online monitoring instrument and meters as well as remote monitoring system can be allocated for the specific demand
of users, for example: UV lamp monitoring system, UV intensity monitoring systems, water temperature detection system and disinfection time
accumulating system, etc.

The manual or automatic cleaning devices can be allocated according to the users' demand.

Process flow
When preparing the pure water or high-purity water, predesalination is often conducted with the reverse osmosis units and the ion exchange process is taken for deep desalination. The ultrafiltration device is adopted to further remove the colloids, microorganisms, bacteria and mechanical particles in the water. The main process flow for preparing the pure water or high-purity water with the ultrafiltration units consists of:
Raw water Pre-Processing RO Ion exchange Ultraviolet sterilizer
Ion exchange UltrafiItration User

Effectively treating water with higher concentration levels than listed above can be accomplished, but may require added measures to improve water quality to treatable levels. If, for any reason, it is believed the UV transmission is not satisfactory, contact the factory.
UV wavelength (nm)

               DOSAGE is the product of intensity & time
dosage=intensity*time=micro watt/cm²*time=microwatt-seconds per square centimeter
                            (μW-s/cm²)
             Note:1000μW-s/cm²=1mj/cm²(milli-joule/cm²)

As a general guideline, the following are some typical UV transmission rates (UVT)

City water supplies	850-980‰
De-ionized or Reverse Osmosis water	950-980‰
Surface waters(lakes, rivers, etc)	700-900‰
Ground water(wells)	900-950‰
Other liquids	10-990‰

Optimal service condition
As UV is a short- wavelength light wave, it has low radiant energy and weak penetrating power and can only kill the microorganisms it directly radiates on. Therefore, in order to enhance the bacteria-killing efficiency and ensure the security of drinking water, the incoming water into the sterilizer must meet the following standard, (and if exceeding the following standard, the killing efficiency may be affected).
