4.1.1 A PW/ WFI Pretreatment and Production system starts at thevalve (inclusive) before the first supplied water filter component/ MMF.
PW/WFI 预处理和生产系统的系统边界开始于第一个供水过滤器组件/多介质过滤器之前的阀门(包括阀门)。
4.1.2 APW/ WFIPretreatment and Production system end boundary is atthe inlet valve (inclusive) ofthe PWjWFI storagetank or at the POU if a tank is not installed.
PW/WFI 预处理和生产系统的系统边界末端位于PW/WFI 储罐的进水阀(包括)处,如未安装储罐,则位于使用端。
4.1.3 ThePW/WFI storagetank should not be includedin the PW/WFIPretreannent and Production.
PW/WFI 储罐不应包含在 PW/WFI 预处理和生产系统中。
4.1.4 "Industrial" treatment systemsupstreamto the PW/WFI Pretreatment and Production. Including supplyto other plant utiliti steam boilers, potable water usage, feed to cooling towers etc. should not be includedin the PW/ WFI Pretreatment and Production.
PW/WFI预处理和生产上游的"工业"处理系统。包括向工厂其他公用设施的供应,如蒸汽锅炉、饮用水使用、冷却塔进水等,不应包括在 PW/WFI 预处理和生产系统中。
4.2 General system requirements
系统一般要求
4.2.1 A "build clean"concept shall be employed duringthe installation of PW/WFI Pretreatment andProductionsystems: supply of piping/ tubingand equipment in clean condition and installation methodsthat prevent ingress of contaminants.
在安装PW/WFI 预处理和生产系统时,应采用"洁净施工"概念:提供洁净条件下的管道和设备,以及防止污染物进入的安装方法。
4.2.2 Incoming feed water shall meet local standards or WHO standards for potable water. Ifthis is notthe case, additional systems shall be installed to improve the water feed parameters before the PW/W FIPretreatment and Production.
原水应符合当地标准或世卫组织饮用水标准。否则,则应安装额外的系统,以改善PW/WFI预处理和生产系统前端的进水参数。
4.2.3 The PW/WFI Pretreatment and Production water quality shall show improvement in all qualityparameters as the water advances through the system.
越往PW/WFI 预处理和生产系统的后续阶段,水的所有质量参数应越好。
4.2.4 The following parameters shall be steadily reduced at each stage in the system:在系统每个阶段,应稳步减少以下参数:
∙microbial total count;
∙微生物总数
∙conductivity and;
∙电导率
∙TOC
∙TOC
4.2.5 PW/ WFIquality shallbe according tothe last revisionof the local/national/relevant
Pharmacopoeia. Table 1provides recommendedwater quality.
PW/ WFI 质量应根据当地/国家/相关药典的最新修订版本进行。表1提供了建议的水质。
