What are the technical requirements for UV disinfection equipment systems?

Ultraviolet disinfection equipment is a sterilization device that uses ultraviolet germicidal lamps to irradiate and eliminate microorganisms such as bacteria and viruses. It is widely used for UV disinfection of reclaimed water from municipal wastewater, effluent from urban sewage treatment plants, and effluent from industrial wastewater treatment facilities. Today, Editor Let me introduce you to ultraviolet disinfection equipment. System What are the technical requirements? ？

 

1 Low-voltage lighting system

 

The low-pressure lamp system is suitable for low-flow water treatment systems or small-scale water treatment plants. The operating temperature of the UV lamp is around 40 degrees Celsius.

 

2 Low-pressure high-intensity lighting system

 

The low-pressure high-intensity lamp system is suitable for medium-sized wastewater treatment plants. Its UV output can be adjusted according to changes in water quality and flow rate, thereby optimizing energy consumption and extending the service life of the UV disinfection equipment. Typically, the operating temperature of UV lamps is around 100 degrees Celsius.

 

3 Medium-voltage lighting system

 

The medium-pressure lamp system is suitable for water treatment systems with high suspended solids and low UV transmittance, as well as large-scale wastewater treatment plants. It boasts high disinfection efficiency and strong UV penetration capability. The operating temperature of the UV lamps is around 700 degrees Celsius.

 

4 Aging coefficient and lifespan

 

The aging factor can be used to calculate the effective UV dose of ultraviolet disinfection equipment based on an aging factor that has been verified by a third party. If no third-party verification is available, the following can be used: 0.5 Calculate using the default value.

 

The cumulative operating life of medium-pressure lamps in ultraviolet disinfection equipment must exceed 3,000 hours; the cumulative operating life of low-pressure and low-pressure high-intensity lamps must exceed 12,000 hours.

 

Ultraviolet disinfection equipment System What are the technical requirements? Different types of equipment have their own specific technical requirements. You can choose the appropriate UV disinfection equipment based on your actual needs.
