What Is UV Water Filtration?

Ultraviolet water purifiers use a built-in ultraviolet lamp to generate short-wave ultraviolet rays with a central radiation wavelength of 253.7nm to sterilize the water flowing through the reaction chamber, thereby solving the problem of exceeding the bacterial indicator of drinking water and making the water quality contaminated by bacteria reach and exceed the country Sanitation standards for drinking water.

UV water purifier

1. The application wavelength is 225-275m, and the peak value is 254m

1. Water supply system with rivers, lake ponds and well water as sources of water.

2. Water supply system for high water tank and reserve water tank and reserve water tank.

3. Food, pharmaceutical, beverage and wine making industries.

4. Various water supply systems that need to be sterilized and disinfected.

3. Model description: ST-MU- * **-***

U: UV water purifier

*: Specifications, specifications of inlet and outlet

**: Import and export type (P: horizontal Z: vertical)

***: System rated working pressure: (Unit: MPA)

The iron content is related, so the quality of the water to be treated entering the equipment, that is, the conditions for entering the water are as follows:

1. Chroma 15 degrees;

2. Turbidity 15 degrees;

3.Iron content0.3mg / L;

4. E. coli 800 cells / L.

The bactericidal rate is 99%, and the E. coli is 0cuf / 100ml, which complies with the "Quality Standard for Drinking Water Purification" stipulated in CJ94-1999 "Industrial Standard for Urban Construction of the People's Republic of China".

1. Input power: 220V, 50Hz;

2. Adapt to water temperature: 60 ;

3. Service life: 10-15 years;

4. Product specifications: DN20 ~ 150 for inlet and outlet.

1. This equipment can only be sterilized and cannot change other indicators of water, such as color and turbidity. If these indicators exceed the standard, they need to be handled by other methods;

2. When the quality of the raw water exceeds the national drinking water standards, such as: chromaticity higher than 15 degrees, turbidity higher than 5 degrees, and iron content higher than 0.3 mg / L, other methods should be used to purify the standard first, and then ultraviolet water purification The total number of bacteria is more than 3000 / ml, and the coliform group is more than 800 / ml. Multiple units should be used in series or the flow rate should be reduced as necessary to achieve purification standards.

3. The ultraviolet lamp is a wearing part and needs to be replaced when its life expires.

1. The equipment must be installed horizontally, and there must be 1 meter and 0.4 meter space at both ends in order to replace the lamp;

2. The quartz tube and lamp tube inside the device are fragile. Pay attention during installation and transportation;

3. When installing the UV lamp, pay special attention to protect the suction port of the lamp (the tube wall has a prominent protrusion at one end). The exhaust port should be slowly pushed into the casing, and collision with the exhaust port is strictly prohibited, otherwise the lamp tube will be permanently damaged;

4. Ultraviolet water purifier must not bear the weight of external pipes;

5. The pipeline installation should be installed as shown in the diagram. Shut-off valve 1 is the main pipeline valve. It is closed during normal operation. Shut-off valves 2 and 3 are inlet and outlet valves of ultraviolet water purifiers. They are open during normal operation. Sampling valves 1 and 2 are water detection ports.

6. After the installation of the pipeline is completed, the water outlet valve should be opened first, and then the water inlet valve should be slowly opened to ensure that the internal mechanism of the ultraviolet water purifier is not subject to the violent impact of the water flow and enters the working state normally;

7. If the instrument alarms during use, open the protective covers on both sides and replace the indicated lamp;

8. Two consecutive times of igniting the UV lamp at least 10 minutes apart, and then ignite after the lamp tube has cooled; during use, it is strictly forbidden to exceed the working pressure to prevent damage to the quartz sleeve.

1. 12 months warranty and lifetime maintenance;

2. The UV lamp is not included in the warranty, and users can purchase and replace it by themselves;

3. The artificial damage to the equipment and the loss caused by disassembly are not included in the warranty.

Products have been widely used in the following areas:

Automotive industry: painting, coatings and paint filtration

Electronics industry: pre-treatment of process water, tape coating, air pre-filtration

Food and beverage industry: juice, mineral water, milk, brewing, vinegar, cooking oil, syrup, etc.

Petrochemical pharmaceutical and chemical industry: Lubricants, chemicals, oils, hot solvents, phosphate coatings, etc.

Bio-pharmaceutical industry: biological and fermentation, filtration of pharmaceutical water, washing water, high-viscous, cosmetics, etc.

Environmental protection: industrial and domestic water, textile and papermaking wastewater, metal cutting fluid, cleaning and cleaning agent filtration

Printing, furniture industry: ink, paint, resin, wax filtration

Ultraviolet disinfection technology has been used for a long time. We commonly use it as the surface of food factory workshops, equipment, packaging materials and ultraviolet disinfection cabinets. The hottest water purifier products now also incorporate ultraviolet disinfection technology. UV water purifiers work like other UV disinfection products. The perfect combination of ultrafiltration technology and ultraviolet sterilization technology of water purifier products solves the problem of exceeding the standard of drinking water bacteria index, so that the water quality contaminated by bacteria reaches and exceeds the national drinking water related sanitary standards.

In recent years, ultraviolet rays have been used for sterilization of transparent liquids. The working principle of the UV water purifier: the strong ultraviolet light generated by the wave-band ultraviolet light generator illuminates flowing water, air or solid surfaces. After a certain dose of ultraviolet light radiation, the DNA structure in its cells is destroyed, thereby killing bacteria, viruses and other pathogens without using any chemical drugs. Reached the purpose of disinfection and purification.

1. High-efficiency sterilization: Generally, the sterilization rate of bacteria and viruses by ultraviolet rays can reach 99% -99.9% sterilization rate in one to two seconds.

2. High-efficiency sterilization and broad-spectrum: The broad-spectrum of ultraviolet sterilization is the highest, it can kill almost all bacteria and viruses with high efficiency.

3. No secondary pollution: UV sterilization does not add any chemicals, so it will not cause secondary pollution to the water body and the surrounding environment, and will not change any components in the water.

4. Safe and reliable operation: Traditional disinfection technologies such as chloride or ozone, the disinfectants themselves are highly toxic and flammable substances, and the UV disinfection system does not have such hidden dangers.
