How to Choose a Medium-Pressure UV Sterilizer? A Detailed Guide to Medium-Pressure UV Disinfectors

Select Medium-pressure UV sterilizer First, it’s important to understand the composition of medium-pressure UV sterilizers. A medium-pressure UV sterilizer is a type of UV sterilizer that, compared to low-pressure UV sterilizers, boasts several advantages, including higher power, a wider sterilization range, the ability to eliminate residual chlorine, and the absence of photoreactivation phenomena. Setting aside low-pressure UV sterilizers, let’s focus solely on medium-pressure UV sterilizers—these devices consist of the following components:

 

Composition of the medium-pressure UV sterilizer:

 

1 Cylinder: The cylinder for medium-pressure ultraviolet lamps is a stainless steel outer shell designed to provide a disinfection environment for the UV lamp tubes.

2 · Control System: The control system is divided into mechanical control and... PLC Control, generally speaking PLC Relatively precise control.

3 Ultraviolet lamp system: The core component of a medium-pressure UV sterilizer, it comprises an ultraviolet lamp tube, a quartz sleeve that isolates the lamp tube from contact with water, and a ballast. This is the key component used for water treatment and disinfection; all other components serve to ensure the proper operation of the UV lamp system.

4 — Intensity Detection System: Intensity detection refers to the portion of the system that monitors the light intensity of the lamp tube using an intensity probe, providing data for the self-cleaning system or serving as a basis for replacing the lamp tube.

5 Self-cleaning system: Since impurities in the water can contaminate the quartz sleeve, reducing its light transmittance and thereby compromising the sterilization efficiency of the UV sterilizer, the self-cleaning system works by having cleaning components mounted on the sleeve move along its surface, effectively removing the impurities adhering to the sleeve and restoring the quartz sleeve’s original light transmittance.

6 Other: Other components used for the normal operation of the equipment or for convenient maintenance.

 

The medium-pressure UV sterilizer mainly consists of the following components; among them, the lamp system is the component that distinguishes it from the low-pressure UV sterilizer. The most critical components are the lamp and the ballast. The quality of the lamp is primarily determined by the following indicators:

1 )、Ultraviolet radiation illuminance. The higher the illuminance, the higher the purification efficiency.

2 ) The photoelectric conversion efficiency refers to the efficiency with which electrical energy is converted into light. Similar to a car’s fuel consumption, the higher the efficiency—meaning the same amount of electricity consumed results in more ultraviolet light—the better the lamp tube is.

3 )、Low light decay.

4 ), the moment when the lamp tube starts and rises.

5 ), the service life of fluorescent lamps. The lifespan of fluorescent lamps varies widely, ranging from a few hundred to several thousand hours.

 

Product features of medium-pressure UV sterilizers:

 

1、 Environmental protection: Produces no chemical byproducts, environmentally friendly, and highly efficient.

2、 Broad-spectrum sterilization: Utilizing medium-pressure UV lamps, it provides full-spectrum disinfection regardless of microbial species and effectively destroys them. DNA Prevent resurrection

3、 Small in size and easy to install—simply connect it to the pipeline via a flange.

4、 The domestic power industry already has several successful deployments, and user feedback indicates excellent performance. This is a proven, mature, and reliable piece of equipment.

5、 Intelligence: Equipped with intelligent monitoring and an automatic control system that automatically adjusts the UV lamp power based on water volume and water quality.

6、 No need to shut down—replace the UV lamp online, requiring only... 3~5 minute

7、 The system has low operating costs (only electricity consumption) and low maintenance costs (only the UV lamp is a spare part).

 

Economic benefits:

 

1、 Completely replaces non-oxidizing biocides, significantly reducing chemical costs.

2、 Reduce the frequency of reverse osmosis membrane cleaning and the replacement frequency of security filter cartridges, thereby extending the service life of both membranes and filter cartridges.

3、 Reduce the pressure drop across the reverse osmosis membrane, increase water production, and lower the cost of concentrate treatment.

 

Principle of Water Disinfection and Sterilization by Medium-Pressure Disinfectors

 

The treated water enters the cavity of the UV sterilizer through the inlet. The ultraviolet light waves exert cavitation, mixing, cleavage, oxidation, flow promotion, bactericidal, and algaecidal effects on the water, thereby achieving auxiliary sterilization and degradation of organic substances. The localized shock waves generated in the process induce turbulent flow in the treated water, ensuring more thorough and uniform contact between the water and the ultraviolet light, thus delivering a more efficient sterilization effect. At the same time, the ultraviolet light waves are combined with specific wavelengths. 253.7nm Strong ultraviolet radiation C(UVC) Irradiate the water flow to achieve further broad-spectrum sterilization, enabling the treated water to attain a sterilizing effect in a very short time.
