5 Mercury Vapor: The UV lamp also features mercury vapor, which fuels the lamp via vaporization.

6 Sealed Enclosure: The entire assembly is sealed with O rings to prevent water from seeping into the UV
enclosure.
Advantages of UV Water Purifiers

1 Effective Pathogen Elimination: UV rays kill most harmful pathogens, ensuring safer drinking water.
2 Chemical-Free: Unlike some other purification methods, UV purification doesn’t require chemicals.
3 Low Energy Consumption: UV purifiers consume minimal electricity.
4 No Altered Taste or Odor: UV treatment doesn’t affect the taste or smell of water.
Disadvantages of UV Water Purifiers

1 Inability to Remove Non-Living Contaminants: UV purifiers don’t remove non-living impurities like heavy
metals, chemicals, or dissolved solids.
2 Dependent on Water Clarity: Water must be clear for effective UV treatment.

3 No Storage: UV-treated water should be consumed immediately; it doesn’t remain disinfected over time.
Maintenance Cost
The maintenance cost for UV water purifiers primarily includes replacing the UV lamp periodically. Regular
cleaning of the quartz sleeve and pre-filters is also essential.
Result: Thus, the remove all useless thing from the water successfully.
