1. Apply ultraviolet spectroscopy with a wavelength of 225-275 μ m and a peak at 254 μ m, which has high energy. UV sterilizers have strong bactericidal effects and can destroy the nucleic acid structure of microorganisms, thus achieving the purpose of disinfection.
2. The equipment can effectively kill Escherichia coli, dysentery bacteria, Legionella, influenza virus, hepatitis virus, etc., purifying water quality.

3. The rates of various viruses and bacteria in seawater, freshwater, or other water bodies treated by the equipment can reach 99.99% or more.
4. Illuminate water with a strong UV (ultraviolet) light source. This disinfection system can quickly take effect without any residue, and does not require any potentially hazardous chemicals.
5. The water treatment system integrates UV light sources into the filtration device. A typical complete filtering device has a multi-layer structure, including a UV light source and a traditional mechanical filter. A series of special light sources, ballasts, and sleeves suitable for integration in filtration devices have been used to achieve ultraviolet water sterilization equipment. This easy-to-use and easy to install technology can protect community residents from the threat of diseases caused by microorganisms such as bacteria and viruses carried by water. Suitable solutions for different market demands, able to meet the special needs and installation requirements of residents and municipal drinking water, wastewater treatment, industrial water, swimming pools, and other leisure facilities.
6. The UV sterilization equipment adopts an integrated design of a controller and a water processor (if necessary, a special modular design can be used). The controller consists of a UV lamp working indicator circuit, a programmable time controller, a time accumulation controller, and an electronic ballast; The water treatment unit consists of a closed pressure cylinder, inlet and outlet pipes, an automatic cleaning quartz sleeve, ultraviolet light tubes, and left and right heat dissipation covers for the tubes.

Characteristics
The ultraviolet sterilizer consists of a ultraviolet lamp, quartz tube, ballast, seal, tank, inlet and outlet, and other parts.
◎ Adopting the world's American Lysos low-voltage high-strength ultraviolet lamp tube, the service life of the lamp tube is guaranteed to be over 12000-13000 hours.
Select high transmittance and high-purity quartz sleeves to ensure that ultraviolet rays pass through at least 90% and withstand a pressure of over 15MPa.
◎ Choose the world's advanced constant and high-intensity ultraviolet special ballasts to ensure the maximum actual output of the ultraviolet lamp power, which can guarantee the normal operation of the entire system in complex situations.
Select high-quality stainless steel as the reactor (304 material, 316 material), and perform special polishing treatment on the inner wall of the reactor to improve the sterilization effect.
The sound and light alarm system can promptly reflect whether the equipment is working properly.
Equipped with a time control system, it can control the working status of the system in different time periods to achieve energy conservation.
◎ UV intensity monitor, timely monitoring of UV light intensity to ensure sterilization effect.
◎ Diode fuse ensures the safety and stability of the system in case of abnormal power supply.
◎ Cleaning system: The cleaning system is divided into manual cleaning and automatic cleaning for different users to choose from.
The power supply is generally 220V50Hz, and can also be customized according to different users for various voltage and frequency bands.
The exterior design conforms to fluid dynamics, ensuring that the equipment has no dead corners and that the ultraviolet radiation intensity inside the equipment cavity is uniform and uniform.
The equipment is designed according to the NSF TITLE 55 standard in the United States, with an effective dose of over 99.9%.

7Selection principles and precautions
1. This device can only disinfect and sterilize, and cannot change other indicators of water, such as color, turbidity, etc. If these indicators exceed the standard, other methods need to be used for handling;
When the original water quality 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 milligrams per liter, other methods should be used to purify and meet the standards first, and then treated with ultraviolet disinfectors; If the total number of bacteria exceeds 3000/mL and the coliform group exceeds 800/mL, multiple units should be connected in series or the flow rate should be reduced as appropriate to achieve disinfection and sterilization standards.
3. UV lamps are vulnerable parts and need to be replaced when their lifespan expires.
8、 Installation and use
1. The equipment must be installed horizontally, with a space of 1.5 meters and 0.4 meters at both ends for replacing the lamp tube;
2. The quartz sleeve and lamp tube inside the equipment are fragile items, and attention should be paid during installation and transportation;
3. When installing ultraviolet lamps, special attention should be paid to protecting the exhaust port of the lamp (there is a noticeable protrusion on one end of the tube wall). The exhaust port should be slowly pushed into the sleeve, and collision with the exhaust port is strictly prohibited, otherwise it will cause damage to the lamp tube;
4. The ultraviolet sterilizer shall not bear the weight of external pipelines;
5. Pipeline installation should be carried out according to the schematic diagram. Cut off valve 1 is the main pipeline valve and is in a closed state during normal operation. Cut off valves 2 and 3 are the inlet and outlet valves of the ultraviolet sterilizer and are in an open state during normal operation. Sampling valves 1 and 2 are the detection water inlet;
After the pipeline installation is completed, the outlet valve should be opened first, and then the inlet valve should be slowly opened to ensure that the internal mechanism of the ultraviolet sterilizer is not strongly impacted by the water flow and can enter the working state normally;
7. If the sterilization equipment alarms during use, open the protective covers on both sides and replace the indicated light tube;
8. Ignite the ultraviolet lamp twice continuously with a minimum interval of 10 minutes, and wait for the lamp tube to cool before igniting; During use, it is strictly prohibited to exceed the working pressure to prevent damage to the quartz casing.
9、 After sales service
1. 12-month warranty, lifetime maintenance;
2. The ultraviolet lamp tube is under warranty, and users can purchase and replace it themselves outside the warranty period;
3. Artificial damage or damage caused by dismantling and modification of ultraviolet disinfection equipment is not covered by the warranty.
