Six Technical Features and Application Areas of Open-Channel UV Disinfection Systems

As is well known, Open-channel UV sterilizer Made from food-grade stainless steel, the ultraviolet disinfection unit features non-toxicity, rust-free performance, pressure resistance, corrosion resistance, and no risk of metal ion contamination. It fully meets food-grade hygiene requirements. The open-channel UV disinfection unit is suitable for water supply systems in various buildings and other backup water storage tanks. It is also ideal for food and beverage processing plants as well as independent water supply systems of various pipe diameters and flow rates. Additionally, the UV disinfection unit can be used in marine vessels and field-based systems.

 

The open-channel municipal wastewater UV disinfection system, developed based on research findings, adopts a modular design. The size and dosage of each module are custom-designed according to variations in treatment capacity and water quality. The disinfection modules are installed within the disinfection channel, along with other components located on the bank, and... PLC The control unit constitutes the disinfection system. A UV disinfection system generally consists of seven components: ① UV lamp module; ② junction box; ③ ballast control cabinet; ④ PLC Master control cabinet (HMI box); ⑤ Pneumatic equipment and air compressor; ⑥ Lifting equipment; ⑦ Overflow weir and related auxiliary components, etc.

 

One, Open-channel UV disinfection system The six key technological features

 

1、 The system's effective ultraviolet dose is no less than 30 mJ/cm² The effluent meets China’s Class I standard. A Mark;

 

2、 The UV lamp employs low-pressure, high-energy solid-state amalgam technology. The lamp tube can withstand high-power loads, with a power density that can exceed— 2W/cm , service life 12000 Hour;

 

3、、 PLC The control center features an operator interface, module status monitoring, an emergency stop alarm system, a data acquisition system, online monitoring, and manual operation. / Many features, such as automatic cleaning control;

 

4、 The quartz sleeve is made from high-purity quartz and has a specific thickness. 1.5mm , light transmittance 90% Above;

 

5、 The disinfection equipment features fully automatic mechanical cleaning equipment equipped with a water-level automatic control weir gate.

 

6、 The system is equipped with ultraviolet monitoring probes. The probes are specially designed and tailored for... 254nm The UV-transmitting filter transmits data on changes in the UV intensity within the channel to the central control cabinet.

 

The open-channel (frame-type) ultraviolet disinfection unit uses UV lamps arranged on UV disinfection modules positioned within an open-channel trench to emit ultraviolet radiation at a central wavelength of... 253.7nm The short-wave ultraviolet radiation sterilizes and disinfects water flowing through drainage ditches, thereby addressing the issue of excessive bacterial levels in treated wastewater and ensuring that the bacteria in discharged water meet China’s relevant discharge standards.

 

The sterilization principle of open-channel UV disinfectors is that as water flows through the UV disinfector, ultraviolet light irradiates bacteria and viruses, damaging their cells and structures and ultimately causing them to die, thereby achieving the purpose of sterilization.

 

II. Application Areas for Open-Channel UV Disinfectors:

 

Secondary water supply systems for high-rise buildings such as hotels, restaurants, office buildings, and residential complexes; various small-scale, independent water supply systems serving industries including pharmaceuticals and healthcare, food and beverage processing, and chemical manufacturing; potable water supply systems for nearshore vessels; other field-based water supply systems; as well as industries involved in rural water supply upgrades, municipal water supply, and wastewater treatment equipment.

 

 

The open-channel UV disinfection system has been meticulously designed by technical experts and features a low-water-resistance UV disinfection module with independent intellectual property rights, achieving lower water resistance and higher reliability. Each standardized UV disinfection module consists of a stainless steel lamp holder, a UV lamp tube, a quartz sleeve, a cleaning mechanism, a power distribution system, and a data acquisition system. The entire UV disinfection system is composed of several such UV disinfection modules, making it easy to install, operate, and maintain.
