The appearance of the municipal water supply ultraviolet disinfection device should be neat and beautiful, without obvious hammer marks or unevenness. The panel instruments, switches, indicator lights, and signs should be installed firmly and upright. The welding of the equipment casing and skeleton should be firm, without obvious deformation or burn through defects. Key points for construction and installation. It is not easy to install the ultraviolet generator on the outlet pipe close to the water pump to prevent damage to the quartz glass tube and lamp tube caused by water hammer when the pump is stopped. Install strictly in the direction of water inlet and outlet There should be a foundation that is higher than the building floor, and the height of the foundation above the ground should not be less than 100mm. The connecting pipes and valves should be firmly fixed, and the UV generator should not bear the weight of the pipes and accessories. Installation should be easy to disassemble, inspect and maintain, and materials that affect water quality and hygiene should not be used at all pipeline connections.

The operation of municipal water supply ultraviolet disinfection equipment is safe and reliable: Traditional disinfection techniques such as using chlorides or ozone, whose disinfectants themselves are highly toxic and flammable substances, do not have such safety hazards in ultraviolet disinfection systems. Low operation and maintenance costs: UV sterilization equipment occupies a small area and has simple structural requirements, so the total investment is relatively small. In terms of operation costs, it is also relatively low. At the level of 1000 tons of water treatment capacity, its cost is only half of chlorine disinfection.

The effectiveness of the municipal water supply ultraviolet disinfection device can achieve a removal rate of over 99.99% for various viruses and bacteria in seawater, freshwater, or other water bodies treated by the municipal water supply ultraviolet disinfection device water sterilization system. Under the premise of a water virus and bacteria removal rate of over 99.99%, the cost of treating each ton of water ranges from 4 cents to 1 cent RMB. Improving the cultivation of seedlings in seawater and freshwater has resulted in a survival rate of over 50%. Accelerate the growth rate of aquaculture populations.

Characteristics of UV Disinfectors for Municipal Water Supply

The municipal water supply ultraviolet sterilizer is made of 304/316 stainless steel material, polished inside and outside, and has the characteristics of corrosion resistance and not easily deformed; The B municipal water supply ultraviolet disinfection device is equipped with a work indicator light, a power cord plug with power-off protection, a time counter, and an ultraviolet intensity detector (optional); The C municipal water supply ultraviolet disinfection device is equipped with a high transmittance pure quartz sleeve and a high stability sterilization lamp tube, with a service life of over 9000 hours and a constant UV-C ultraviolet band output during the service life; The municipal water supply UV sterilizer is equipped with a UV specific ballast, which ensures stable operation and guarantees the lifespan and efficiency of the UV sterilization lamp; For small disinfection equipment, PVC can be used as the material for the water connector.

The surface of the municipal water supply ultraviolet disinfection device should be smooth and flat, without any significant defects that affect its appearance, such as unevenness or bumps.

The paint layer should be firm and uniform, without bubbles, accumulation, or flow marks.

The surface of die-casting parts should be smooth, free of pores, sand holes, obvious cold insulation lines, etc.

The outer shell of the electrical cabinet should be undamaged.

Raw materials and materials for municipal water supply ultraviolet disinfection equipment

The enclosed disinfection chamber used for disinfecting drinking water, urban sewage recycling water, urban sewage, hospital wastewater, and livestock and poultry breeding wastewater should use other materials with equivalent UV resistance and corrosion resistance.

Protection level of ultraviolet equipment

The pressure resistance (water pressure) of the enclosed disinfection chamber should not be less than 0.8MPa; For UV disinfection devices without pressure requirements, the pressure resistance should not be less than 0.2MPa.
