Open channel ultraviolet disinfection equipment: a practical choice for water quality safety guarantee
2025.03.14
As a physical disinfection method, the open channel ultraviolet disinfection equipment is becoming a key equipment in the modern water treatment system with its high efficiency, safety and environmental protection characteristics. In the field of water treatment, the disinfection link is directly related to water safety. Although traditional chlorine disinfection methods are cheap, they can produce harmful byproducts and have limited inactivation effect of some pathogenic microorganisms.
1. technological superiority
UV disinfection technology uses specific bands of UV light to destroy the DNA structure of microorganisms and lose their ability to reproduce. The study shows that the ultraviolet light with the wavelength around 254nm has a significant inactivation effect on most pathogenic microorganisms, and the inactivation rate can reach more than 99.99%. Compared with chemical disinfection methods, ultraviolet disinfection does not produce disinfection by-products and does not change the chemical properties of water.
The open channel design enables the equipment to handle large flow water, and the treatment capacity of a single equipment can reach tens of thousands of tons per day. The modular structure can be adjusted flexibly according to the actual needs, and it can be used for both large water plants and small water supply systems. This design significantly improves the applicability and economy of the equipment.
In terms of operating cost, although the initial investment of ultraviolet disinfection equipment is higher, the long-term operating cost is lower than that of chemical disinfection method. Modern ultraviolet lamp tube life can reach more than 12000 hours, and the energy consumption is low, greatly reducing the operation and maintenance costs.
2. Performance of the devices in practical applications
After using the open channel ultraviolet disinfection equipment in a city waterworks, the effluent water quality reached the national standard stably, and the qualified rate of microbial index remained at 100%. In the past three years of equipment operation, no water quality safety accidents have occurred, and the user satisfaction has been significantly improved.
In terms of operation and maintenance, it is equipped with intelligent control system, which can monitor key indicators such as ultraviolet intensity and water quality parameters in real time to realize automatic operation. Maintenance work mainly includes regular replacement of lamp tube and cleaning of quartz casing, easy operation and low maintenance cost.
Compared with traditional chlorine disinfection, ultraviolet disinfection equipment covers a small area and does not need to build chlorine adding room and chlorine storage facilities, which saves a lot of infrastructure investment. At the same time, the risk of chlorine gas leakage is eliminated, and the safety of the water plant is improved.
3. Equipment application prospect and development trend
With the continuous improvement of water quality standards, the application scope of ultraviolet disinfection technology in the field of water treatment is constantly expanding. In addition to drinking water treatment, it is also widely used in sewage treatment, reclaimed water reuse, swimming pool water treatment and other fields. In particular, UV disinfection shows advantages against drug-resistant pathogenic microorganisms.
Technological innovation promotes the continuous improvement of equipment performance. The new generation of ultraviolet disinfection equipment uses highly efficient LED ultraviolet light source, with lower energy consumption and longer life. The intelligent control system can realize the remote monitoring and fault diagnosis, which further improves the reliability of the equipment.
In the context of increasingly strict environmental policies, the environmentally friendly characteristics of UV disinfection technology make it a broad market prospect. It is expected that in the next five years, the market size of ultraviolet disinfection equipment in China will maintain an average annual growth rate of more than 15%.
The promotion and application of open channel ultraviolet disinfection equipment marks the water treatment industry to a safer and more environmentally friendly direction. With the continuous progress of technology and the accumulation of application experience, this efficient disinfection method will play a greater role in ensuring the safety of water quality and provide better drinking water for the people.
