In stainless steel systems, the compatibility of the gasket used with the disinfection method must be checked. At present, the widely used gasket material is PTFE or EPDM, both of which have good thermoelasticity and excellent high temperature resistance, ozone and chemical disinfectant. Other gasket materials must be carefully checked for compatibility with the disinfection method to ensure that no material leaks into the water. The key is to recognize that the building material “does not react, does not add or absorb, and does not change the safety, identity, strength, quality or purity of the drug, thereby exceeding the requirements of other standards.â€
2.4 Initial disinfection steam disinfection may be a reliable disinfection method. However, there is no requirement for steam disinfection of purified water or WFI systems. The following procedure is recommended as an alternative to hot water disinfection in an ambient temperature system.
Immediately after passivation of the stainless steel system, flush the system with high temperature (80 ° C 5 ° C) process water and open all valve rinse points. Generally, it is necessary to reach the flushing water test to indicate that the passivating chemicals are not detected or the conductivity of the inlet and outlet water is equivalent, which is the initial disinfection of the system. Once chemical testing has been used to determine the chemical characteristics of the process water quality, microbial samples should be collected after each component, point of use, and storage tank. If the test results indicate that there is no live bacteria contamination in the distribution system where each sampling point is located. Then, the system should be immediately lowered to its operating temperature and stabilized.
Disinfection of pharmaceutical water
1 disinfection system design 1.1 construction materials Currently, the materials used in the tanks and pipes widely used by Zui are usually 316L stainless steel. This material can be adapted to the requirements of most disinfection methods. Disinfection measures such as heat sterilization, UV or ozone can be used in stainless steel systems without restrictions. When the selected raw materials meet the requirements, in order to avoid corrosion of the stainless steel distribution system, factors such as concentration, pH and temperature during chemical disinfection must be considered.
