uv water treatment plant

UV water purifiers consist of a chamber containing a glass quartz sleeve, which holds the UV lamp. This lamp emits UV-C light, which penetrates the quartz sleeve and disinfects water flowing through the chamber. The quartz sleeve is needed to prevent water from touching the lamp. The system is sealed by one or two o-rings.
