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.

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).

Limitation of Use
The UV water disinfection system NOT intended for the treatment of water that has an obvious contamination or intentional source, such as raw sewage, nor is the unit intended to convert wastewater to microbiologically safe drinking water.

Water Quality (in)
Water quality plays a major role in the transmission of germicidal UV rays. It is recommended that the water does not exceed following maximum concentration levels

Maximum Concentration Levels (Very Important)
Iron≤ 0.3ppm(0.3mg/L)
Hardness≤ 7gpg(120mg/L)
Turbidity≤ 1NTU
Manganese≤ 0.05ppm(0.05mg/L)
Tannins≤ 0.1ppm(0.3mg/L)
UV Transmittance≥ 750‰

Applications

 → Waste water treatment

 Increased attention to environmental protection may cause increasing use of UV disinfection systems instead of chlorination in more than 70% of waste water treatment plants in domestic market, as UV treatment does not produce DBPs (disinfection by-products) at all. Now various facilities from small automated village sewage treatment plants to large ones apply UV treatment systems, and the application has also diversified, which could mean UV treatment is generally approved as the effective and cost-efficient way of waste water disinfection.

→ Drinking water

In order to destruct pathogenic microorganisms which exist even after several steps of treatment 

processes, UV treatment has been suggested as the solution instead of conventional treatments that have their own limits such as insufficient treatment, cost burden, environmental pollution, deterioration of water quality or odor. UV does not cause odor or DBPs (disinfection by-products) and effectively inactivates several pathogens like Cryptosporidium, Giardia which are highly 

tolerant to chlorination. UV is used worldwide in millions of drinking water treatment plant as it guarantees stable performance, can minimize chlorine input, is easy to operate, and is not affected by water temperature or pH value.

→ Food & beverage

The food and beverage industry demands strict quality control such as HACCP (Hazard Analysis Critical Control Point) Program as the products need to be preserved as theirs original tastes and flavors and to be sterilized. Variety of food and beverage process is equipped with UV disinfection systems as they can sterilize the products without any change in quality and shape. Besides, production equipments and sanitary facilities for production staff also use diverse technology applying UV techniques.

→ Swimming pool, spa, sauna

Swimming pool, spa and public sauna maintains some level of chlorine in the water for continual 

disinfection. Feeding chlorine is an effective way of disinfection, but its by-products forms chloramines causing displeasure for bad smell, irritation on eyes or skin, and deterioration of the facilities. As an alternative solution UV treatment does not produce odor, is highly effective in inactivating pathogens, can reduce the quantity of chlorine feeding so that easily satisfy the visitors there.

→ Zoos, aquaria and dolphinaria, aquaculture

Zoos and aquaria always have infection or odor problem resulting from their own excrement, secretion, and other leftovers. These facilities often have difficulty removing algae which keep deteriorating the artificial breeding environment e.g. forming toxin or low level of dissolved oxygen, and might cause mass infection, low breeding coefficient, and underdevelopment. UV treatment does not affect ecosystem under water or produce toxic by-products, and now a lot of breeding facilities are equipped with UV disinfection systems.
