PW water system strictly purifies the raw water to make it meet the water quality standards for pharmaceutical production, and the process from water production to delivery to the water point is easily subject to secondary pollution, which will affect the final water quality effect. Therefore, , Purified water equipment must be transported in strict accordance with the corresponding standards.
1. At present, pharmaceutical PW water system is mainly transported through pipelines. Therefore, both pipelines and transfer pumps should be cleaned regularly, and regular disinfection and sterilization should be done. Pharmaceutical purified water equipment can only be put into use after it has been verified and qualified.
2. PW water system should improve anti-pollution performance, and should use stainless steel pumps that are easy to disassemble and disinfect. If necessary, the compressed air and nitrogen should be purified when compressed air or nitrogen pressure is required.
3. PW water system should be transported by circulating pipelines, and there are certain standard requirements for pipeline design. In order to control the microbial content, the piping design should avoid dead pipes and dead ends to avoid contamination due to the presence of residual water. Pipes can be made of stainless steel or other materials that are proven to be non-toxic, corrosion-resistant, and do not leak contaminating ions. The valve should be a sanitary valve without dead angle, and mark the flow direction of the purified water.
The pharmaceutical industry has high requirements for water quality, and the safety and quality of water quality directly affect the effect of drugs, and even threaten human life and health. Therefore, pharmaceutical PW water system must be certified by GMP to ensure the safety and reliability of water in the production line.
