It is widely recognized in the pharmaceutical industry that sterilization is necessary to ensure the biosafety of wastewater discharged from facilities subject to infectious diseases. Among others, an important part of the equipment is “the hold tube”. The hold tube is a thermal insulating pipe for ensuring a sterilization temperature and a sterilization time for sterilization. We have developed a continuous sterilizer and verified the design and sterilization effect of the hold tube, which is important for sterilization process. Through tracer tests and simulation analysis, we have designed an appropriate pipe diameter and length at the optimum Reynolds number. It is also possible to make the hold-tubing more compact by increasing the sterilization temperature, and it is confirmed that the continuous sterilizer is effective in applying to infectious wastewater.
