A Beijing-based university has invented a water generator which can kill the H5N1 strain of bird flu completely, the university reported Thursday.

The "killer", called "HTDJ-15 acid oxidizing potential water generator", was invented by Hantong Science and Technology Company of Beijing Union University.

This new sterilizer can convert water into disinfectant which, by keeping PH scale below 2.7, can kill all the animalcules.

In addition, the used disinfectant can be deoxidized into ordinary water, causing no harm to human skin and environment.

This invention has just been approved and certified by the country's Ministry of Health, the State Drug Administration and the State Intellectual Property Office respectively.

The water generator as a sterilizer is currently in extensive use abroad, such as in hospitals, restaurants and hotels.
