Most waterworks in our country have adopted single chlorine disinfection. Chlorine disinfection has certain limitations and instability, such as difficulty in controlling all microorganisms, particularly in killing "two worms", without significant removal.

The medium-pressure ultraviolet technology can inactivate various kinds of protogenic unicellular bacteria and viruses including cryptosporidium and giardia intestinalis, and has no chemical by-products.

Medium pressure uv lamps can produce a broader uv spectrum and thus can act on the entire microorganism, not just on the DNA structure of the microorganism. It is precisely because this UV technology effectively avoids the occurrence of DNA revitalization and dark repair in microorganisms, and therefore permanently inactivates the microorganisms, which is clearly of great importance in drinking water. In addition, medium pressure ultraviolet light disinfection is more powerful than ozone and chlorine disinfection in killing bacterial species and decomposing chemicals. The method has the advantages of no pollution, environmental protection; the occupied space is small, and the installation and the operation are simple and convenient; the operation cost is low, and the service life is long; the sterilization function is not influenced by the environment, and the like.
