What is the primary purpose of quartz sleeves in UV disinfection?

The primary purpose of quartz sleeves in UV disinfection is to protect the UV lamps. Quartz sleeves act as a protective barrier around the UV lamps, ensuring that the ultraviolet light emitted by the lamps can effectively disinfect the water without being obstructed.

These sleeves are made from quartz glass, which has excellent transmission properties for UV light, allowing the maximum amount of ultraviolet radiation to reach the water. By protecting the UV lamps from physical damage and contamination, the quartz sleeves help maintain the efficiency and functionality of the UV disinfection system. This ensures that pathogens in the water are effectively inactivated, providing a safe and clean water supply.

Moreover, while measuring UV intensity, controlling water flow, or affecting water hardness are important factors in a comprehensive water treatment system, they do not relate directly to the specific protective function provided by quartz sleeves. Thus, the correct choice emphasizes the role of quartz sleeves in maintaining the operational integrity of UV disinfection systems.
