り付けであるが、１００％殺菌出来るわけではない。When sterilizing pure water with conventional pure water production equipment,
Because the piping is not heat resistant, chemical sterilization using hydrogen peroxide, formalin, etc. is the main method, which is time-consuming and requires flushing after sterilization, and in addition, the pure water supply must be stopped for several days. It had some flaws. Recently, there are devices that use heat-resistant pipes and other equipment that can be heat-sterilized, but these are unnecessarily expensive compared to non-heat-resistant pipes, and the high temperatures cause safety problems. is the current situation. Although the pure water supply system is equipped with an ultraviolet sterilizer, it does not guarantee 100% sterilization.

。The present invention was made to solve such problems from a practical standpoint.The main technology of this invention is to heat a pure water supply system at 40°C for 6 hours, as shown in Figure 1. This is based on new knowledge that bacteria in pure water can be sterilized by holding water at 50'C for 12 hours or more. Next, the present invention will be explained in detail by way of examples.
