Which component in a UV system protects the lamp while transmitting UV radiation?

The quartz sleeve is an essential component in a UV system because it serves the dual purpose of protecting the UV lamp from environmental factors while allowing UV radiation to pass through. The sleeve is made of a special type of glass that is transparent to UV light, meaning that it does not absorb or interfere with the UV radiation emitted by the lamp. This is crucial because any obstruction or absorption of UV light could reduce the effectiveness of the disinfection process that the UV system is designed to achieve.

Additionally, the quartz sleeve helps keep the lamp clean from contaminants, which is important for maintaining efficiency and ensuring that the maximum amount of UV light is transmitted to the water being treated. If contaminants were to build up on the lamp, they could block the UV radiation, reducing the system's capability to disinfect effectively. Therefore, the quartz sleeve plays a vital role in the operation and efficiency of UV disinfection systems in wastewater treatment.
