The device is placed at the outlet end of the water circulation equipment. As water flows from one end to the other, the flowing water is disinfected by invisible UVC light. The effectiveness of disinfection is related to the length of time the water is exposed to the UVC light and the strength of the UVC light.

This device uses the principle that UV light can destroy the replication and reproduction of DNA.  When bacteria, viruses and algae in the water are irradiated by a certain dose of UVC, the DNA and RNA structure of their cells are destroyed and the cells are unable to regenerate, thus achieving disinfection and purification of the water body.
