Ultraviolet Disinfection Unit

　　Working Principle

　　This device utilizes ultraviolet light in the 225–275 μm wavelength range, with a peak at 254 μm, which corresponds to a highly energetic spectral band. This band exhibits potent bactericidal activity, thereby achieving disinfection. As water flows through the water treatment unit and is exposed to UV irradiation, the bacteria present in the water are immediately inactivated.

　　The flow transmitter converts the measured flow signal into a standard analog signal, which is then fed into the programmable controller’s analog input module. The programmable controller compares and processes the received analog signal to determine the appropriate number of UV lamps to activate based on the flow rate.

　　Performance Advantages

　　(1) Ultraviolet disinfectors feature high output, strong bactericidal efficacy, rapid action, and excellent performance; they do not alter the physical or chemical properties of water nor introduce any off-flavors.

　　(2) The ultraviolet germicidal quartz lamp tubes shall be professionally manufactured products certified by the national health and disease prevention authorities, featuring high light transmittance, minimal energy loss, low power consumption, and a continuous service life of over 3,000 hours.

　　(3) The housing of the UV drinking water treatment unit is fabricated from high-quality, food-grade stainless steel imported from overseas, offering a service life 5 to 10 times longer than that of aluminum alloy products, with superior pressure resistance and no risk of metal ion contamination.

　　(4) The electrical control section is integrally designed with the cabinet, resulting in an aesthetically pleasing appearance, a compact footprint, convenient and flexible installation, simple operation, and easy management.

　　(5) A microcomputer is used for real-time monitoring of water flow, which controls the number of UV lamps that are switched on to ensure uniform and stable UV irradiance, thereby achieving energy savings and extending the service life of the lamps.

　　Scope of Application

　　This product is suitable for small-scale domestic water supply systems that draw water from rivers, lakes, ponds, and well water, particularly those employing elevated water tanks and backup storage reservoirs. It is also ideal for water disinfection in the food, beverage, and brewing industries, as well as in swimming pools.

　　Product Specification, Model, and Configuration Selection Table

　　1. Product Configuration Description:

　　(1) This equipment only disinfects and sterilizes; it does not alter other water quality parameters. If users have additional requirements, custom orders can be placed.

　　(2) When the raw water quality exceeds the national drinking water standards, such as: color exceeding 15 degrees, turbidity exceeding 5 degrees, and iron content

　　If the concentration exceeds 0.3 mg/L, other purification methods should be employed to bring the water up to standard before using a UV drinking-water treatment system for further treatment.

　　(3) When the total bacterial count exceeds 2,000 cells/mL and the total coliform count exceeds 1,000 cells/L, multiple units should be operated in series or the flow rate should be reduced as appropriate to meet the purification standards.

　　(4) The number of UV lamps can be effectively adjusted based on the actual water flow rate, thereby avoiding the simultaneous operation of all UV mercury lamps and extending the service life of the disinfection unit.
