First of all, we should have an insight in other germicidal solutions before we discuss the UVC germicidal solutions. As is known to all, traditional sterilization methods generally include chlorination, odorous oxygen, and mercury lamp sterilization.
Chlorination sterilization: is adding chlorine to the water to achieve the purpose of disinfection, and generally water plants will use this method. Generally, chlorine will evaporate by heating, but some residual chlorine will inevitably be left in the water, which will cause high incidence of cancers such as esophageal cancer, stomach cancer, rectal cancer, bladder cancer, and prostate cancer.
Ozone sterilization: At room temperature, ozone gas is a lavender gas with a special fishy smell, and its solubility increases as the temperature decreases. It has a strong sterilization method. However, when the concentration is too high, the decomposition time of ozone is prolonged, the ozone that is not completely decomposed has a great smell, and it has greater damage to the human respiratory tract, nervous system, and immune system.
Mercury lamp sterilization: Mercury lamp sterilization is currently a widely used method of sterilization. But mercury is highly toxic, and bad control will have serious consequences. For example, the Minamata disease that occurred in Japan in the 20th century was caused by mercury pollution. Therefore, many countries have signed the Minamata Convention, which will abolish the use of mercury lamps in 2020.
In contrast, Let us see what advantages UVC light disinfection has.
UVC Is Efficient and Safe
For example, UVC Germicidal Fixtures increase the value of all air conditioning and air-circulating systems by:
1.Maximizing system efficiency
2.Prolonging blower life
3.Providing healthier air to breathe
Treating air that passes through an HVAC unit with ultraviolet light will reduce, or eliminate, DNA-based airborne contaminants (bacteria, viruses, mold spores, yeast, protozoa), and provide much healthier air to breathe. UVC Germicidal Fixtures are a labor-free solution that will not harm occupants, equipment or furnishings because they produce no ozone or secondary contaminants. For more than 70 years, tens of thousands have been safely installed in hospitals, clinics, processing plants, commercial offices, manufacturing sites and other commercial facilities and multi-and single-family residences around the world.
Simple operation and maintenance, low cost
Ultraviolet disinfection technology is not only the highest disinfection efficiency of all disinfection methods, but also its operation and maintenance are simple, and the operating cost is low, up to 4% or less per ton of water. Therefore, its cost performance is the highest among all disinfection technologies. It has both Other disinfection technologies are incomparable with high efficiency, and have the advantages of low cost and low operating costs. At the level of 1000 tons of water treatment, its cost is only 1/2 of chlorine disinfection, 2/5 of chlorination and dechlorination disinfection, and only 1/9 of the cost of ozone disinfection. Even at the level of 100,000 tons of treatment, the investment and operating costs of ultraviolet disinfection equipment are far lower than other disinfection technologies.
Wide application field
Among all the current technologies, none has such a wide range of applications as UV technology. It can not only disinfect fresh water, but also sea water; it can disinfect not only drinking water, but also waste water. It can Widely used in a variety of fields that require water disinfection. For example: freshwater and seawater disinfection in aquaculture, shellfish purification, agricultural processing water, purified drinking water, electronics, medicine, ultra-pure water for commercial filed, biological industry, various beverages, beer And food processing, etc.
