What are the advantages and disadvantages of UV disinfection equipment?

Now the domestic UV lamp fulfills the Chinese industry standard of straight tube type quartz ultraviolet low-pressure mercury disinfection lamp. The high power of the lamp is 4W, and the useful life is generally 1000-3000h, while the useful running time of the imported low-pressure lamp can reach 8000~12000h. Medium voltage lamps can also reach 5000~6000h. In contrast, the use of domestic lamps will increase maintenance costs. Therefore, the development of long-life UV lamps or the introduction of foreign advanced UV lamp production technologies is a problem that is now waiting to be solved. So today's UV sterilization equipment manufacturer Tianrun Environmental Protection introduced the advantages and disadvantages of UV sterilizer:

Advantages of UV sterilization device

1. Can quickly and effectively kill various bacteria, viruses and other microorganisms;

2. After photolysis, it can be useful to degrade chloride in water;

3. Simple operation and convenient maintenance;

4. Small footprint and large amount of treated water;

5. No pollution, strong environmental protection, no toxic side effects;

6. Low investment cost, low operating cost and convenient equipment installation;

7. Using the optical principle to design a unique inner wall treatment process, so that the cavity can be used with a large amount of ultraviolet rays, so that the sterilization effect is doubled.

8. Fast disinfection and high efficiency. According to the test results, it can be sterilized by ultraviolet rays for several tens of seconds. In general, the uniform removal rate of E. coli is 98%, and the uniform removal rate of total bacteria is 96.6%. In addition, spores and viruses that are difficult to kill by liquid chlorine can be removed.

9. Does not affect the physical properties and chemical composition of the person, does not increase the smell and taste of water.

10. Simple operation, easy to manage, easy to complete automation, ready to use. Unlike chlorine dioxide, there is a reaction time.

The disadvantage of ultraviolet sterilizer is that it has large power consumption and short life.

The primary drawback of UV sterilizers is their power consumption and lamp consumption. The life of a lamp is typically 1 to 2 years. As the lamp ages, it will lose 30% to 40% of its strength. On the other hand, the quartz tube should be cleaned at intervals, otherwise a thin film will appear on the quartz tube, which can block the ultraviolet rays and reduce the anti-virus effect of the ultraviolet sterilizer.
