The working principle of the UV sterilizer is to use ultraviolet rays (UV-C band) to irradiate liquids, destroy the DNA or RNA structure of microorganisms (such as bacteria and viruses), make them lose their replication ability or activity and die, thereby achieving the purpose of disinfection. The specific process is as follows:

1.Water flow in: The liquid enters the ultraviolet disinfector through the water inlet.

2.Ultraviolet irradiation: The liquid flows through the quartz sleeve area equipped with ultraviolet lamps, and the ultraviolet rays of about 253.7nm emitted by the lamps penetrate the liquid and destroy the DNA or RNA structure of microorganisms.

3.Bactericidal effect: The bactericidal efficiency of ultraviolet rays is proportional to the wavelength, radiation intensity and irradiation time. Under normal circumstances, the irradiation dose must meet certain standards to ensure the killing rate.

4.Water out: The liquid after ultraviolet irradiation flows out from the water outlet to complete the disinfection process.

1.Highly efficient sterilization: UV sterilizer can kill 99.99% of bacteria and viruses in a short time (usually within 10 seconds), and are suitable for the disinfection of various liquid fertilizers.

2.No secondary pollution: UV sterilizer do not use chemical agents, do not produce harmful byproducts, and do not change the physical and chemical properties of liquids.

3.High degree of automation: Modern UV sterilizers are usually equipped with automatic control systems, which can achieve unattended continuous operation and reduce labor costs.

4.Wide range of applications: UV sterilizers are not only suitable for liquid fertilizer production, but also can be used in other agricultural fields such as soilless cultivation, nutrient solution circulation irrigation, etc.
